Preparations from coniferous diseases. Fungicide for coniferous trees

Conifers in the garden design

Coniferous trees are unpretentious, but they need help if they have become infected with the fungal causative agent and a detrimental impact of pests. The main problems faced by the owners coniferous rocks - Spit, rust, tracheomekosis and insects.

1

This disease is typical only for representatives of coniferous rocks, it provokes fungal pathogens - ascomycetes. Depending on the nature of the manifestation, several forms of this disease distinguish.

Spit on ate

Real spit - One of the main reasons for premature decay of the needles of firs. In the risk area, young, as well as weakened conifers come to the risk. The needles spruce infected with this fungus become brown, dry and fall. Such symptoms can be observed in the spring and early summer. But in the fall, the disease is manifested in the form of small yellow dots on the needles of ate, which gradually darkens. And on the branches where needles crumbled, black bodies are formed - this is a spore fungus. In such a cocoon, fungus perfectly worries winter frosts, and in the spring again crashes out.

Snow Schute - This kind of fungus can be found almost on all types of coniferous, including ate European, blue, conic, twisted and ordinary. This disease is a special danger for snow-covered and northern regions, where it can even completely destroy fir. Infection with fungus occurs already at a temperature of 0 degrees, and very rapidly. The pathogens of this sickness of firings cause the convergence and dying of coniferous needles after melting snow. For summer season The fungus is increasingly progressing, the spruce becomes first reddish, and then light gray, as in the photo. The needles begins to crumble and falls. By the autumn, the spore fungus becomes more noticeable, dotting with black branches. Favorable conditions for further spread fungus are falling out and melting of snow in autumn, drizzling rain, heavy snowfall and protracted spring.

IN preventive purposes Do not forget to cover decorative ate in your garden, especially the spruce horse. Although it is considered a frost resistant, shelter for the winter does not hurt.And it will also protect the conic from sun burnswhich she will help get from the beginning of February. As a protective material, use burlap, film, cardboard, leaving the bottom of the bottom open to avoid the debate.

Brown Schute or Snow Brown Mold. Amazing absolutely all kinds of ate (including blue varieties). Manifest in early springWhen it starts to melting snow. The ideal temperature conditions for development is the mark from 0 to +1 degrees. On dead brown coniferous needles, a black and gray raid and point body spores fungus are noticeable. With such a disease of the needles, it may not be imposed for a long time, and thin branches die gradually. Provokes a disease thickening landing and high humidity air.


Snowy brown mold

Preventive measures include: selection of more resistant coniferous varieties (fir twisted and European), regular thinning of thickened landings, timely destruction of patient crumbling needles and dried branches, as well as processing of fungicides. Having lined with a cheva, pay attention to the intensity of entering the sunlight. Remember, the shaded places are perfect conditions for spreading spruce, especially for small dwarf trees - a spruce of conic and barbed. Treatment of firings is carried out with copper-containing and sulfuric drugs - 1% burglar liquid, Abiga Peak, Hom. As prevention, use these fungicides for spraying in early spring and autumn. With a high risk of infection, the needle treatment is also carried out in summer.

Coniferous needles acquire a reddish tint and shuffled? It is worth carefully look at the root system. Typically, such signs indicate a very unpleasant and dangerous soil disease - tracheomekosis. Most often, this type of disease is striking young coniferous plants with a surface root system and a low-rise rod root. Such rocks applies. Unfortunately, this fungal disease is not amenable to treatment, and fir dies. The plant must be removed along with the ground and burn, and the soil itself, where the conic grew, disinfection with mortar copper Kaper.

Rust fungal pathogens are striking coniferous needles and bark of shoots. Their disputes are very quickly applied to neighboring plants, causing them significant deformation. Here are some of the most common varieties of rust coniferous rocks.

  • Rust needle. The development of fungus occurs in early spring. On the needles there are chaotic-plated yellow bubble pustulas. If the disease is launched, ate loses its decorativeness - their needles are starting to turn quickly and prematurely fall.
  • Pine spit, bubble or columnar rust. Infection begins with needles of coniferous rocks, and then applies to the bark and branches. At the site of the affected rust plots, resin is distinguished, and yellow-orange bubbles perform from cracks on the cortex - the eciastulas, they can be seen on the photograph. The fungita forms thickening, which over time provoke the formation of open wounds. Damaged shoots are greatly bent and dry.
  • Rust of cones and fir spit. The inner side of the fir scraps is amazed by rounded dark brown esiopulas. This leads to a wide disclosure of cones and incorrect seeds. If the fungus provokes the curvature of escapes, such a form of a sickness of fools is called a spruce spit. The main carrier of the dispute of this fungus is a cherry.


Rust fir

In preventive purposes, try to plant coniferous trees away from plants that have a tendency to infection with rust, such garden crops include poplar, aspen, black currant, cherry and their hybrids. Conduct a constant trimming of affected shoots, cut the dry branches and delete the fallen needles on time. Treatment of fir trees from rust carry out by spraying with drugs Phytosporin-M. and Abiga Peak.

Let's start, perhaps, from the most important pest - a paustic tick. They affect absolutely all kinds cultural plants. Their main activity is manifested in spring and summer in hot dry weather. Cellic ticks feed with cellular juice. The presence of their presence shows the presence of numerous small dots on the needle and entangling needles ordinary web. If the fir is strongly amazed by these pests, the needles are completely white and covered with a numerous cobweb. Carefully looking at it, you can see how the needles are moving. In the quality of these insects, try more often to spray cheese to maintain permanent air humidity.


Spider tick on ate

To combat, use special preparations from ticks - Akaricides Apollo, Borneo, Envidor, Floromite, Flumite, as well as proven insecticides Akarin, Aktellik, PhyTenerm, Oberon, Agrarotin, Conducting a processing several times in one of the following means.

The attack of insect-sawers is most often the conic, Serbian, European, ordinary firAnd also can be found on blue needles. As a rule, those affected by these sucking insects ate on next year Restore. But who truly cause significant damage to the peelers, so it is pine. Sometimes they can form entire sockets from their own excrement and remnants of damaged needles. The sawmaker themselves are also hiding in the nests, cutting the tissue of trees with the help of a special file where they lay the laying of eggs.

Detect such a masonry will not be a lot of work, the appearance of the larvae look like caterpillars. Special activity of peelers manifest from the beginning of May to the end of June. If you do not start fighting with them in time, soon the branches will look exacerbated and will die with time. And get rid of them quite simple. Mechanically remove the visible nests along with the larvae and spray the coniferous plant with one of the following insecticides - Fury, Aktellik, Bi-58, Decis.

If you have noticed numerous moves on the cortex of a coniferous tree, then your spruce populated the dangerous pests - cores. Laying in the royal stroke of the masonry of eggs, they quickly pumped up and, having hatched out of the pupa, tear off holes in the cortex through which outwards come out. If the cores are populated all the tree - it dies. Basically, the attack of these pests are weakened, patients and drying trees. They represent a special danger for small decorative coniferous trees Type of conic (Canadian ate). Good insecticides in the fight against these insect pests are Bi-58, Befentrin, Clipper, Krona Antip.

Early Hermes - their activity can be observed at the end of June. Distinctive features are the formation of small oval Galls at the ends of the branches. In August, you can see the activity of yellow sherry, it is possible to determine the presence of quite large green galls. But at the end of August-early September, late chirmers forming large spherical galls at the branches of coniferous rocks. The pests themselves feed with trees juice. The emerging larvae significantly deform the kidney pine and ate. The outer shell of hurmes is covered with a strong downhill, which makes them almost invulnerable. However, among the insecticides, it is still possible to allocate decent high-performance chemical preparations - Commander and Aktar.


Early Hermes on Tree

Another frequent pest of coniferous breeds is a spruce word. These are small green insects of only 1-2 mm long. After sitting in the colonies, they are able to suck a large amount of juice juice. Strong damage they are applied, such as conic or canadian fir, as well as blue needles. It is possible to notice the presence of Tlima by the formation of numerous ant nests around the tree. The needles themselves are equipped with yellow spots and dry. Insecticides help struggle with these pests Aktara, Match, Dursban. If the damage is strong, the first spraying is recommended to conduct Aktarova, and with alternation in 2 weeks drugs Match and Dursban. As prevention in May-June month, spend a two-time spraying Dursban, as well as take care of the destruction of ant nests - the main satellites of Fir Tlima.

White fluffy raids on the needles of trees and shrubs testifies to the presence of tole-hurmes. Cover from wax fibers, resembling snowflakes, protects insects from moisture loss.

Shrubs and trees under which they do not grow food plants, protecting from pests more convenient, because protective events can be carried out at any time of the year and feared less chemicals. And it is known that the effectiveness of spraying depends not only on the selection of appropriate drugs, but also on the timing of their use.

Malicious pests coniferous plants are Tly. The saliva overwhelmed the fertilized females of Tly-Hermes on the seeds of fertilized females is caused by the formation of cisheooba-different growths with cherry - galls, inside which the offspring of the tool develops. In July-August, the winged individuals are overwhelmed from Galov, which fly to larch, where they do not form galls, and sucking juices suck. They are protected by white fibrous discharge and look like fluffy white flag. Winter under the scales of the bark and next spring Eggs are laid out, of which the winged males and females will repense. After fertilization, females are returned to fir, where and winter. Obtaining galls, you can significantly reduce the damage caused by pests. With the "fluffy flush" on the larch fight, spraying with mineral oil, which dissolves the finest wax fibers. And most importantly, it should not be seated near spruce and larch. The appearance of the Tly can be prevented, spraying trees before the appearance of young shoots, and then after they have thrown, Decis or Fastakas.

A green spruce rate of about 2 mm highlights toxic saliva for the plant. The needles are yellow (in a strongly affected silver spruce become gray-violet) and fall. This "baldness" begins with the trunk, only fresh May shoots remain healthy. You can make sure that the attack can be assumed if you shake the branches, spreading white canvas under the tree. It is easy to detect green insects with red eyes. Mass reproduction of this tli happens after a soft winter. It is possible to avoid the "baldness" of the firings, spraying them with systemic insecticides acting on sucking insects, in particular the name-com.

Decorative coniferous often damages the bustling pine (butterfly from the leaflerting family), the larvae of which are being introduced into young shoots or kidneys. The kidneys dry out, shoots are twisted. If damage is a bit, affected kidneys and shoots removed from the tree and burn. In the case of a mass lesion at the end of April spray the Fastak drug.

If the spring scaly leaves of the Tui and the cypressov are raving and the tops of the shoots die, maybe they started the mining mole-blunthouse. The moves sprinkled in the tissue of the leaves with tiny larvae, and the caterpilots themselves can be seen on the lumen. In order to prevent butterflies, affected by the plants in late June - July twice with an interval of 8 days are treated with means containing pyrethroids.

At the beginning of summer, orange growths appear on branches and trunks of juniper, which in dry weather, have a type of tongues with a length of 0.5 cm, and after the rain turn into fleshy formation of 1.5 cm long. These are organs of the sporing organs of mushroom rust. To pass the full cycle, it requires two host plants. The wind transfers countless microscopic disputes on the hawthorn bushes, rowan or a pear, where they germinate and the threads of the mushroom are embedded in the leaves. On the upper surface of the leaves, yellowish-brown spots are formed, and on the bottom - the honesty protrusion, from where the disputes, which now have to get to juniper for further development. The only effective measure is not to plant the host plants, but when signs of the disease appear, remove the partner less valuable for you. It is true, however, try to destroy rust with two-three spraying from the weekly intervals of Caprol or Ditan.

Pests and diseases are more often condicted on weakened plants that lack nutrients. It is necessary to apply feeding with special preparations and balsams for conifers, as well as create conditions for the development of insects, destroying pests: god's cows, Zlatagoznok, Mukh-buzz.
Evergreen shrubs and rhododendrons
Due to the improper leaving the plant often suffer from chlorosis. Particularly susceptible to this disease Rhododendron. The first signs of the disease - the breath or unnatural yellowness of the leaves - indicate the lack of the main photosyntheing pigment - chlorophyll. This can be caused by the overpowering of the soil, excess lime, as well as a lack of magnesium and iron salts in it. Long stay in such soil leads to the elimination of the shrub. Chlorosis can be avoided if the soil must be properly prepared before planting the plants (there are ready-made substrates for various varieties plants). If the plants are already sick, should partly change the soil and spray the bushes every 10 days 0.1% solutions of magnesium and iron sulfate alternately.

Diseases and pests of coniferous rocks.
There is an erroneous opinion that coniferous - very comfortable plants, they are not whimsical, durable and, the main thing is not subject to any disease. I planted, spruce, juniper or pine, and no more problems. Nothing like this! Coniferous, like everyone else, are subject to various diseases, and pests are not considered. Take at least Hermes, sawers, or a well-known Koroad-Tograph. Many of them damage young shoots, havoy, resulting in taking and drying different parts Plants, which in turn leads to a decrease in or complete loss of decorative qualities, and sometimes to the death of the plant.

The first symptom, which should alert, is the yellowing and serving of individual branches. it normal story: beautiful plant With a fluffy healthy crown, purchased in a nursery or garden center, it was planted in all the rules on a good sunny area with a drainage system, in the soil, aligned with the bridal chernozem. It would seem that everything is done correctly, but the plants suddenly begin to shut and dry. Many immediately begin to take various measures, mainly water the plants of growth stimulants from Kornin to Epina, for some reason there are no results. Unfortunately, growth stimulants, not a panacea from all troubles, although their use is useful.
If there is no full-fledged nutrition for the plant in the soil, and it gives a big shoot of shoots, our pets are doomed to the fact that they are prematurely starting to turn yellow and dry out old branches, giving all incoming substances to young growth points. In addition, it turned out that the bridal black soil does not always contain a sufficient amount of nutrients: potassium, nitrogen, phosphorus. Therefore, when landing should be applied additionally, various fertilizers.

Incompute nutrition is the main reason for the yellowing and drying of coniferous plants. Exactly the same picture can be observed when driving or, on the contrary, the harness of the root system, which is often observed in the absence of drainage or on light sandy and sandy soils.

Enormous harm to plants are numerous pathogenic microorganisms, developing both on the crust and on the courtying. Most often it is mushrooms. It all starts very prose. A small bug flew or fillesenzing the beetle, damage the twig or the cup, immediately penetrated the smallest arms of the mushroom through the wounder, the mushroom was formed and began to live at the expense of alive tissues of the plant. At first I was poured, then the twig, half of the plant, and gradually it remains on the pine only the top, and from juniper - one name. We always find it too late when the decorativeness of conifers is hopelessly lost. As a result, it is necessary to completely replace the diseased plants. At the same time, there is no guarantee that the new young pine planted on the same site does not get sick and will not lose his shape, for example, from attacking rust. So, for the pine Waemutov in May - June bubble rust or cancer, is the main disease that she suffers every year. Moreover, further rust goes to currants and gooseberries. In addition to this, pine attacks are noted: the rust of the seedlings of seedlings, pine vertun, resin cancer. From the diseases of the branches, the scleroderria cancer was widely distributed, in which the formation on the trunk of deep cancer, crust of the bark and kidney and kidney kidney. At the same time, the needle becomes a reddish-brown and no longer pops. Often, stem rotes appear on pines, caused by development in the lower part of the truder mushrooms, occurs. And the names of stem rotes are some: Pestro-red rotten rotor, mixed rot, brown central fractured rot from roots, etc. In each case, the disease can only determine specialists. If the conifers began to turn yellow and silent, and the truder's fruit bodies appeared on the trunk - in the plants, stem rot, and they are doomed to death. IN last years The main disease of the conifers is spying, causing yellowing and swallowing the needles. Cedars, pines, spruce, pseudotsuga and juniper are sick. The needle becomes a reddish-drier with black transverse lines; Over time, it is formed by black shiny sporing points, disputes with which quickly rewrite the neighboring branches and plants. There is still a snowy spider, in which the chevings become dirty gray and covered with fine gray mushrooms.

A very many pathogens mushrooms are described, which cause another ailment - drying the branches of coniferous plants. And all begins in the same coughing and drying of the chewing. True, if you look closely, the chevings remain clean, without visible shortens and raids, but on the branch's branch, necrosis is noticeable, taking, and with heavy rains, a grayish mushroom is developing on the crust. There are also such moments when the wet and cold spring mushrooms, causing rust on the shoots of juniper, besides the usual orange plaque form abundant sporing in the form of a jelly jelly.

So do not be surprised if there are separate yellowes from your conifers, the main thing is to quickly determine the cause. If these are traces of the activities of numerous pests, the plants can be sprayed during the vegetation by the preparation of "Decis". If the pests are not detected, eliminate the soil factor and adopt the plants with complex fertilizers for coniferous crops.

The worst option is mushroom diseases. In this case, it is necessary to remove highly infected branches and spray all the plants with copper oxychloride or other copper-containing drugs. Processing is better to carry out systematically, for example, one or twice in spring and in August - September. And do not believe those who say that
roughs do not hurt anything, for all plants you need careful care.

One of the most important factors that adversely affect the state of green plantings are pests. The damage caused by them violate the physiological processes, delay growth and development, lead to a decrease in or complete loss of decorative qualities, sometimes to the elimination of individual parts or the complete death of plants. When creating green spaces, first of all, a healthy planting material should be used. It is necessary to carry out measures for plant quarantine, which will prevent pest penetration and diseases to cuttings and seedlings entering, in particular, from abroad.

To protect plants from diseases and pests apply a variety of methods, Fundamentals and faults. Preventive measures are very important, ensuring the cultivation of a good planting material. To grow healthy plants, compliance with agrotechnology is necessary: \u200b\u200bit is necessary to choose the right mixtures, light on mechanical composition and with appropriate acidity, carry out regular loosening of the soil, weeding weeds.

Fertilizers contribute to improving plant growth, root system development. For example, phosphoric fertilizers cause the most quick development of mechanical protective tissues, increase the drought resistance and winter hardiness of plants. To prevent mushroom diseases, prophylactic spraying, pollinating, soil disinfection by fungicides.

Sick plant

Hello, friends! If you have coniferous plantings on your site, then you probably wondered about the diseases of coniferous trees and their treatment. Although coniferous is not particularly capricious in care, but something needs to know about their diseases.

Signs of any disease are determined by the state of the needles, independently of the cedar whether it is, or thuja: the tips of the branches are yellow, they begin to dying, among the green vegetation they appear "sungs", which are already never touched, the tree itself looks sloppy.

Video: How to determine whether the plant is sick?

Types of Rzavchin at coniferous

The most frequent "uninvited guest" on the pine and larch is a fungal rust caused by several types of fungi. With damage to bushes and trees, yellow-orange stains appear on their indoors of the early spring.

Under the clue, it shows that stains are formed with yellow bubble pustulas, located randomly on both sides of the needles. After the mushroom releases the dispute, the body darkens it, becomes a brown-red color, and the branches of conifers look like painted in rusty color.


A bubble rust of pine or cedar looks somewhat differently: it seeks to hit the tree trunk and its branches. At the site of the introduction of the mushroom, the bodies are bursting, the disturbers are visible, pale-orange color. The mushroom is angry with a branch in a circle and its upper part is dying. If such a ringing occurs under the crown, the village will die.

For the treatment, Fungicides "Srins" "Topaz" and "Staters" are used, which are well cleaning conifers from these diseases and contribute to the rapid healing of the fungic wounds. For consulting effect into a solution with a preparation, you can add a potatocide. These drugs perfectly complement each other and the result after their processing is truly storm.

It should be noted that the disputes of these mushrooms develop on weed herb, and then attack coniferous shrubs and trees, therefore, the removal of weeds from the site is an excellent way to prevent these diseases.


Prevention can be considered and timely pruning not only sick branches, but even those who cause you concerns, even if you are unsure that the tree is infected. Try to create the most favorable conditions for the growth of young conifers:

  • process them with immunomodulators - growth regulators that increase the stability of young seedlings to adverse stressful conditions during cultivation and care;
  • in time, make fertilizers and feeding precisely for coniferous trees, watch everyone enough "places under the sun".


If you doubt the health of young people, do not hesitate to contact a specialist. One affected tree can twider all the others on your site.

Fuck fungi and conifer roots. These soilized mushrooms lead to gradual redness (and then taking) roots, after which the roots die, and along with them the plants are dying.

Mushroom, struck roots, penetrates into a vascular tree system, filling the wood with its biomass, overlapping access nutrients. The cut is clearly visible to the darkening of the ring of the core and xylema, the needles turn yellow and falls, a tree or a bush dries.

This disease is a fusarious drying or root rot - almost always flows in a hidden form, you can not guess what the crown of your thui or pine can not yellow and will not become "transparent".

Unfortunately, it is almost impossible to treat such a disease, but to warn it in your power. When transplanting to a permanent place, a seedling should be soaked for several hours in the phytosporin-M solution, "Vitarosa" or "Maxim".

If doubts were born after landing, in the form of prevention, it should be abundantly shedding the soil around the roots of the same "phytoosporin-M", "Agata-25K", "Gamiir", and you can use a fungicide, which is at hand.


In the development of pine resten cancer, or a disease-like disease - Serenyanka cancer, the mushrooms are also musted. But if the first mushroom develops initially on Bolotnaya Matlik and the Lady, then the Sernyanka is moving from pine to the pine.

Infection takes place through a cheva, bruising, the bark of young seedlings, from where mycelium mushroom is spreading already on the whole trunk. The affected area of \u200b\u200bthe cortex acquires a dark gray color, the tree itself dies in 2-3 years. When gray spots are detected on branches and trunks of conifers, it is necessary to immediately begin spraying the "phytoosporin" or "abigapik" and cropped all the branches struck by mushrooms.

As a prevention, you need to adhere to the rule: do not plant the aspen and poplar next to the pines, stay away from black currant bushes.

Here is a pine altitude, like a bubble rust or a columnar currant rust, falls on the coniferous through the currants and the gooseberry, who, first of all, are affected by the leaves. Once on the chew of a cedar or veam pine, gradually the fungus spreads through the whole tree.

In adult trees, the bark cracks, a resin with amber-yellow bubbles explodes abundantly, with the growing of the mushrooms in the areas of lesions, the nodes are formed, above which the branch is first twisted, and then dries away. Young seedlings acquire the appearance of "crumpled elders" and die.

Prevention and struggle measures for all types of rust conifers are the same - improving immunity due to immunostimulants and the use of fungicides and microfertilizers.

Schute


The most common disease that occurs everywhere, and therefore is especially dangerous in thick planted nurseries for growing coniferous species of trees, of course, spider. This disease is typically only for coniferous species of trees.

Begins to spit in May from taking the needles. The following year, after the snow, it is easy to see the black, shiny, as if drawn by the marker, elongated dots. Then the needles "gluits" with a gray web, dark with time. The needles under it becomes brown, but does not appear.

It is a brown spider, striking spruce, pine, fir and juniper. Mushrooms, affecting pines and juniper, different, differ and spin themselves, but the outcome of infection is always the same: thin branches die after sinking of needles, the tree stops in development and in the end dies.

The main risk factors are the density of landings, the increased humidity and lack of nutrition of young shoots. Especially violently illness manifests itself in weakened sprouts, therefore preventive actions should be comprehensive, including not only the removal of fallen needles, immune feeding and fugitial treatments, but also spraying with copper drugs during the whole summer. For example, the drug "Chirachert" has already proved its effectiveness in the struggle to reduce development Schute, not bad and "Horus".

Bacteriosis conifers

There is another common disease - vascular bacteriosis, which many confused with fusariasis.

But the fusarious rot from the roots is the damage to the fungal order, and the bacteriosis is infected with bacteria. And during the fusariosis of the needles on fir paws, it bluses, acquiring the color of rust, and with vascular bacteriosis only fades, the cheops are falling out without changing their painting. Slices of trunk and branches are clean, without dark rings or stains, there are no visible damage and roots.

With the launched state of the disease, the needles sat down with the branches of Niagara Falls with the slightest touch. This is death for wood.

Treatment should begin, as soon as a suspicion of this disease appeared. Shedding the ground "Fundazole". After 3 days - "phytoosporin". A couple of days after "PhytoPorin" - the "zircon" shed. And so until the restoration of a healthy type of coniferous tree is restored.

If there is a potatocid, we use it must, it will not only be the main means of protection, but also the main means of treating our Christmas tree.

To prevent unpleasant trouble on the treatment of conifers, it is necessary to take very carefully to the selection of planting material. And if there are already conifers on the site, it must be remembered that one of the factors contributing to the spread of diseases - mosses and lichens, settled on old trees. 300g iron Camp 10l water will help you to get rid of such an unpleasant neighborhood.

Comments

Each of us would like to have on panstone Beautiful spruce. However, this tree is quite capricious and subject to many diseases. To grow beautiful, high, lush fir, you need to make a lot of effort. The most important thing is correct care. In this article, we consider how the diseases and the alert of the forest beauty of ate may be caused.

Did you know? Spray grows in Sweden, whose age exceeds 9550 years.

Causes of diseases, or basic mistakes when leaving

The main diseases of the ate are caused by fungi, infections or pests. Most often, the causes of coniferous plants are incorrect landing, adverse atmospheric conditions and care, with the consequences of which we have to face:

  • soil with water status;
  • high soil acidity;
  • high density of plantations, as a result, insufficient injection and reproduction of fungal;
  • lack of light;
  • increased air humidity;
  • too deep landing;
  • lack or excess fertilizer;
  • a strong decrease in temperature leads to the death of young plantings;
  • water deficit is a well-known factor leading to the disappearance of plantations.

Important! If the planting of a fir is carried out in a quickly drying ground, the land around the plant is necessarily murdered.

The main diseases of ate and methods of their treatment

Consider which there are diseases of coniferous trees and what causes their treatment. The diseases of the freshers are most often caused by mushrooms and soil pathogens. Among all diseases, which eat, the tree is most susceptible to spider, fusariosis, ulceated cancer. Meanwhile, coniferous disease is not as scary, so I will identify them and treat them further according to the given advice.

The defeat is caused by several varieties of Lophodermium Pinastri mushrooms. There is a disease in Mae month. If you noticed the coughing spruce, it is spitting. With the further development of the disease, the lower part of the needles is covered by brilliant black outlets of point or bar, which over time increases in size. Subsequently, the plant dries and dies. A particularly dangerous disease is for young plants (up to 10 years) and seedlings.

The causes of the spread of fungal diseases ate are warm weather and abundant precipitation (dew, drizzling rain).

The source of the present spruce is a mushroom Lophodermium seditiosum. As a result of this disease, the ate is prematurely falling needle. The seedlings are affected in nurseries and young weak plants. Throughout the spring and summer, the needles will boil and crept.

In the fall on the needles, small yellow dots appear, gradually they increase in size and acquire brown color. The mushroom is saved in a husky blackened needle.

Did you know? Due to the uniform distribution of fibers in wood, spruce best tree For the manufacture of musical instruments.

The causative agent of brown spider, or a snow mold, is a mushroom not cropotrichia nigra. The disease occurs in several stages: contamination of mushroom disputes begins in the fall, the development of the disease proceeds in winter under the cover of snow at temperatures above 0.5 ° C. The disease is manifested in the spring with the occasion of snow.

The symptom of the disease is the appearance on the brown non-shine needle black-gray plaque, similar to a web, and over the time of point fruit bodies, fungus. Thin branches of trees die, the needles are not satisted for a long time. The disease is subjected to young trees, seedlings and self-seeds. Increased humidity The air, a thick planting of plants, depressions on the territory of growth are the main factors that promote the ontogenesis of mushrooms.

The Snow Chute detonator is Phlacidiumin Festans mushroom, which has taken root in highly snow-covered regions. The development of the disease begins under the snow at temperatures about 0 ºC. Infection occurs gradually: from the needle to the needle, and then from the tree to the tree. With the occasion of snow, the affected needles and branches become brown and die away. Sick trees are covered with gray films of fungny.

In the summer, the needles change color from red-red to light gray, begin to crumble, but do not appear. In the fall on the needles, black dots appear. Spores of mushrooms from these points are transferred to the air flows to the still not affected faces before falling out of the snow. Drizzling rain, warm snow-covered winter, tightening spring, loss and melting of snow in autumn favorably affect the spread of mushrooms.

Important! Disputes of mushrooms have long been kept in dead plants and soil, so when transplanting plants from nursers thoroughly process seedlings.

Stewflow control measures are selected of healthy seedlings resistant to disease, advance thinning and spraying coniferous appropriate fungicides, copper-containing and sulfuric drugs.

Tracheosicose fading belongs to viral diseases caused by the soil pathogen. Amazed root system Plants: Roots raw and begin to rot. Mycelium Mushroom damages the Software system, as a result of this, the beneficial substances do not reach the ground part of the plant.

Due to the defective nutrition, the needles acquire red, then brown color, crept, and the tree dries and dies. Saplings are subject to coniferous seedlings during wet cold atmospheric conditions. The symptom of the disease is a gray-white bloom on the needles. The causative agents of the disease are preserved in dead plants and are distributed with seedlings or affected by the soil.

The treatment of fusariosis ate is impossible, a few years later, the plants die. To prevent trachemic and fiction, it is necessary to plant healthy seedlings, carefully remove the contaminated parts of the plants. With the manifestation of primary signs of infection, the processing of biopreparations or fungicides.

Did you know? In autumn, the christmas trees are reset needles.

Rustful diseases of the folsters occupy a special place among all diseases that are susceptible to coniferous, and their treatment should be aimed at eradicating PucciniaStrum Areolatum mushrooms, ColeOsporium, Cronartium Ribicola, which affect deciduous plants. They were most susceptible to such diseases as rusting cones and rust needles.

Rust cones causes PucciniaStrum Areolatum mushroom. The sign of the disease serves the appearance on the inner walls of cones of round dusty brown esi-chip. Subsequently, the bumps are widely revealed and hang, not falling, the seeds lose their germination, the branches are deformed.

The rust path of the needle is a mushroom ColeOSporium. A fungal disease is developing in the spring, hitting a cheva. Bub-shaped ecialasts of yellow color are placed on both sides of the needles. If the plant is struck strongly, the needale changes its color from green to yellow and crept.

If a rust appeared on a her, it is necessary to fight with it, as with other fungal diseases. Also recommended to cut sick branches and make microfertres.

Necrosis of the crust

Nine crust is fungal bark bark disease. Signs of illness: damage and drying of the crust, formation of growths brick color Or dark little bubbles. As a result, the bark is donated, and the tree disappears.

The sulfur of the gray rot is the Mushroom Botrytis Cinerea. The disease affects ground parts of young plants. Branches are gray, brown or black. Covered with conidias similar to a layer of dust. Rewarding the plant continues in the process of growth.

As a result, the trees weaken and lose their appearance. Most often, the disease is distributed in territories with dense landings, poor sun and breathability.

Protective measures to prevent gray rot - it is the advance removal of the affected branches, disinfection of the seats with a solution of copper sulphate. If you think than to treat conifers from diseases as prevention, good tools are a borodic mixture, "Sorrow".

Yazine Cancer ate causes Mushroom Lachnellula Pini. The sign of infection is the appearance on the twins of the twir. Over time, the depressed dumplings appear in the twilight, then the bark is covered with cracks, and closed or open yasers are formed. Thin twigs die without forming an ulcers.

Open ulcers can be dry and wet. Dry look like small tri-fingers brown color. Wet look like a saucer on a short leg, which can be seen over the bark. Ulcers are covered with brown hairs with an orange round gymnial layer. Plants affected by cancer are weak and dry.

The main measure in the fight against cancer is watering under the root of fungicides, processing with copper-containing drugs, timely cleaning of dry branches, treatment of sections of a garden breach. Burning infected branches and needles.

Important! Sick plants and their parts must be removed from the plots.

Fir diseases: disease prevention

You can prevent diseases of the Christmas trees and their treatment, conducting preventive measures. Stick Rules proper landing And the placement of trees, cut off and remove the dried and infected shoots from the site and chew. Be sure to disinfect the slices of trunks. For landing, use healthy and stable seedlings.

Diseases are mostly affected by young, not frown trees. To increase the resistance to infection with sores, microelements, complex fertilizers, increasing the immunity of the plant, are used. Remember, the plant should get moisture moderately. Preventive spraying will help avoid the disease and the death of the plant.
