Processing bushes from pests and diseases should be carried out with the same regularity as the protection of fruit and ornamental trees. Do not forget that the use of chemicals should be discontinued before the appearance of the ovaries. You can resume protective work after harvesting. When selecting planting material for your plot, try to buy those varieties of seedlings that are distinguished by increased resistance to pathogens.
Honeysuckle, actinidia and henomeles are rarely affected by fungal diseases, they also almost do not suffer from pests. But other shrubs are affected almost every year.
In addition to the following diseases affecting fruit shrubs, there are viral diseases that are expressed in the deformation of the shape of leaves and sprouting of crops.
With a description of diseases and pests of shrubs, as well as methods of processing plants you can read by reading this material.
Preparations and terms of processing of fruit bushes from pests and diseases
A gardener who takes care of a fruit garden must, before the onset of spring work in the garden, take care of the purchase of plant protection products. Of course, specific drugs are recommended against each group of pathogens and pests.
But always available must be Bordeaux mixture or copper oxychloride (HOM), copper and iron vitriol, fast or rayek, Inta-Vir, fufanon, actellic and fitoverm. These drugs are used against a complex of diseases and pests in almost all horticultural crops.
Preparations for treating shrubs for diseases and pests are usually sold in small packages. The main thing - just follow the attached instructions.
After spring shrub trimming и pruning trees in March-April, all cuts and cuts are covered with oil paint on natural linseed oil. When cancer ulcers and necrosis are detected, the wood is cleaned to healthy tissue, 1 is disinfected with% copper sulphate and smeared with oil paint.
Every year, before bud break, trees and shrubs are recommended to spray 1% copper sulfate. It falls on the bark of shtambov, stalks and branches, in which many fruiting bodies and mycelium are wintered.
But the most effective period of treatment of bushes from pests and diseases is in the spring, during the swelling of the buds and at the beginning of the growth of leaves. It is carried out depending on the weather conditions in mid-April - early May with a tank mixture of XOM (0,4%) and Fufanon (0,1%) preparations.
With this mixture all berry crops, ornamental and fruit trees are sprayed against a complex of diseases and pests. This treatment is prophylactic for many cultures, and for some - eradicating.
One spring treatment of shrubs from pests and diseases replaces the 3-4 sprays in the summer, which saves both money and strength. In the spring, larvae of pests of fruit shrubs are reflected and many adult individuals emerge from the ground.
Spring spraying not only reduces the number of pests, but also prevents the emergence of the next generations of weevils, leaf beetles, sawflies, aphids and mites.
After flowering of fruit trees, repeated spraying with the same tank mixture is carried out. At this time, pests massively lay eggs in the ovary of the fruit.
And how to treat the bushes from pests and diseases in the summer? When a scab, leaf spot, powdery mildew appears, spray the 1% Bordeaux mixture or its substitutes (HOM, Abiga-Peak), quickly or with a rake.
If necessary, the treatment of shrubs from diseases and pests is repeated after harvesting. With the strong distribution of lichens in the autumn, they clean up their thallus and spray the trees and shrubs with 3% iron sill green.
The following describes the treatment of specific fruit and ornamental shrubs from diseases and pests.
How to treat bushes aronii spring from diseases and pests
Root rot, or chokeberry chokeberry
The causative agent is a mushroom Armillariella mellea. The fungus causes decay of wood roots and trunks, which leads to the gradual drying of shrubs. If near the plant you find mushrooms with yellowish-brown caps on the legs, this means that aronia is dangerously affected by the grass.
The infection in the form of a mycelium is stored in the soil on plant debris, and infection occurs through the root system.
Control measures. Burn dried bushes with roots. At the first signs of infection of shrubs with this disease, pour the soil under the bushes with a solution of Bordeaux mixture or its substitutes at the rate of 1-2 buckets per bush. Spray bushes annually before the fruit body of leaf blooming with the same preparations to reduce the spread of root rot.
Tubercular necrosis of aronia bark
The causative agent is a mushroom Tubercularia vulgaris. With this fruit leaf disease bushes suddenly turn brown and fall off. Numerous brick-red sporulation pads form on drying branches.
Shrubs lose their decorativeness and dry up gradually. The infection persists in the affected cortex.
Control measures. Get quality planting material. Trim dried branches. Conduct regular preventive and eradicating
Chopper leaves septoriosis
The causative agent is a mushroom Septoria sp. The leaves appear light brown rounded spots with a thin dark border. The leaves dry prematurely and fall off, which greatly reduces the decorativeness of the bushes. The causative agents of this disease of berry bushes remain in the remnants.
Control measures. Collect fallen leaves. Spray the bushes in the spring and after flowering Bordeaux mixture or preparations HOM, Abiga-Peak.
Aronia Fruit Rot
The causative agent is a mushroom Monilia fructigena. Berries soften, dry up. On the surface of the dried berries appear numerous light brown pads of sporulation.
Control measures. Remove affected berries. Spray the bushes before the leaves bloom and after flowering with Bordeaux mixture or preparations of HOM, Abigak-Peak.
And how to handle the bushes in the spring from pests-bark beetles? To combat them, Aktara preparations are used; Confidor; "Lepidocide".
Grape diseases and shrub protection
Gray Rot of Grapes
The causative agent is a mushroom Botrytis cinerea. The leaves have large brown spots, often at the edges of the leaf blade. Necrotic tissue cracks and falls out. The infection persists in plant debris and in the affected cortex. Smoky-gray sporulation appears on the infected parts of the plant.
Control measures. Collect and burn all plant debris, cut dried shoots. Spray the drug Speed or Reek.
Spotting and non-infectious chlorosis of grape leaves
The causative agent is a mushroom Septoria ampelina. Large, angular, merging, reddish-purple spots with a dark border appear on the leaves. Wintering dotted fruit bodies form on the spots. Infection persists in plant debris.
Non-infectious chlorosis is manifested during active vegetation and fruiting, especially if there is not enough potassium in the soil. The leaves begin to turn yellow between the veins, often appears brown marginal necrosis.
Control measures. Collect plant residues. Spray the vine before the leaves grow back and after flowering with Bordeaux mixture or its substitutes. Make complex fertilizers in time.
Processing shrubs irgi spring and autumn from pests and diseases
Frost damage to the bark irgi
In the spring, there is a slow release of buds, in the summer - a weak increase in shoots, and at the end of summer the bark cracks and gradually falls. The affected shoots dry out. Fungi infection spreads quickly on weakened bushes and the development of tubercular necrosis of the cortex and leaf spot increases.
Control measures. Cut off the damaged shoots, spray bushes in the spring and autumn Bordeaux mixture or its substitutes to suppress the development of infection.
Tubercular necrosis of the irgi cortex
The causative agent is a mushroom Tubercularia vulgaris. The bark of the affected shoots turns brown and dries out; brick-red spore pads are formed on the surface. Shrubs shadberries dry quickly. The infection persists in the cortex of the affected shoots.
Control measures. Timely thin out thickened planting, remove and burn the affected shoots. Spray bushes before leafing Bordeaux mixture or its substitutes (HOM, Abiga-Peak).
Phylosticctus sprig of irgi
The causative agent is a mushroom Phyllosticta sp. The spots on the leaves are large, rounded, brown-brown in color with a thin dark border and yellow halo. The leaves wither and fall prematurely.
Control measures. Collect and destroy fallen leaves. Spray the bushes before leafing Bordeaux mixture or its substitutes.
Ascohyte leaf spot of shadberry
The causative agent is a mushroom Ascochyta amelanchieris. In the middle of summer, reddish-ocher spots of irregular or rounded shape appear on the leaves of the irgi, without fringing, which eventually merge. Necrotic tissue cracks and falls out. Affected leaves crumble prematurely. Infection persists in fallen leaves.
Control measures. Collect and destroy the affected leaves. Spray the bushes in the spring before leafing Bordeaux mixture, HOM, Abiga-Peak after flowering shadberry and after picking berries.
Gray Rot of Irgi
The causative agent is a mushroom Botrytis cinerea. The disease manifests itself in the form of large brown spots without edging on the leaves, as well as browning and drying of the berries. With an abundance of precipitation, smoky-gray sporulation of the fungus develops. In dry weather, the spots on the leaves crack and fall out, the berries dry out. The infection persists on fallen leaves and berries and in the bark of the shoots.
Control measures. Collect the affected fallen leaves, thin out thickened plantings, remove dried shoots, spray bushes with a preparation fast or rajek.
Irgovyy Semyaed (Megastigmus amelanchieris)
Small brown insect with transparent wings. The females of these pests of shrubs have ovipositoring, with which they pierce green berries and lay eggs in them. The larvae of insect pests of shrubs are white, thick, seeds are eaten in berries.
Control measures. To treat these pests, spray the bushes immediately after flowering with one of the following preparations: fufanon, karbofos, kemifos.
Currant Curved Maker (Pandemis ribeana)
The butterfly is yellow-brown with brown spots. Caterpillars are yellow-green, older green-brown, with a black head. In the spring, these pests of berry bushes feed on the leaves, wrapping them with cobwebs and twisting along the central vein, there they also pupate.
Years of butterflies stretched from late May to late July. The females of these pests of the bushes lay their eggs, the caterpillars feed on leaves and fruits.
Control measures. To treat the bushes from these pests in the spring, after flowering, spray the plants with Fufanon, Karbofos, Aktellik.
Treatment of lemongrass shrubs in the spring and autumn from pests and diseases
Diseases and pests of lemongrass - Schisandra
Tracheomycotic wilt lemongrass
The causative agent is a mushroom Fusarium oxysporum. This soil pathogen infects the roots of plants, penetrates the vascular system and clogs it with mycelium. The affected roots rot, the leaves begin to grow brown along the veins, the plants wither.
A grayish-white mycelium with spores develops on the affected tissues and shoots. The most harmful disease for young plants. The infection persists in the soil on plant debris.
Control measures. Use a healthy planting material, prepare the site with all the requirements of growing this crop. Discard affected plants with roots, collect plant residues.
Tubercular Necrosis of Schizandra
The causative agent is a mushroom Tubercularia vulgaris. The bark of sprouts grows brown and dries out, numerous brick-red pads of sporification appear on it, which gradually dry up. Plants bloom badly and dry out.
Control measures. Cut and remove the affected shoots, collect plant residues, spray the plants before the leaves bloom and in the fall, after the leaves are covered with Bordeaux mixture or its substitutes.
Gray Lemongrass Rot
The causative agent of the disease is a mushroom Botrytis cinerea. Brown, large, rapidly spreading spots appear on the leaves. In dry weather, the necrotic tissue cracks and falls, leaving holes.
With an abundance of moisture on the necrotic tissue, a fluffy, smoky gray sporulation of the fungus develops. In the years with abundant precipitation, gray gil causes drying and premature abscission of the leaves. Infection persists on plant debris and in the cortex of affected shoots.
Control measures. Collect the plant residues, thin out the frequent plantings, spray the plant with the drugs Skor or Raik.
For the treatment of these shrubs in the spring from pests of gall midges, chlorophos, metaphos, and other pesticides are used at concentrations of 0,2%.
Spring and autumn treatment of sea buckthorn shrubs from pests and diseases
How to treat sea buckthorn shrubs from diseases and pests?
Diseases and pests of sea buckthorn - Hippophae
Sea buckthorn stem rot
Rot of sea buckthorn trunks causes rotting fungus - hairy coriolus (Coriolus hirsutus)The fruit bodies of which have the appearance of single, sedentary half-caps of light gray color with a yellow, bristly surface.
Ulcerative necrosis of the buckthorn bark causes the fungus Plowrightia hippophaeos syn. Dothidea hippophaeos. Longitudinal black ulcers appear on the affected wood, the bark dies off, cracks, and spores of the fungus are formed in the recesses. The wood is gradually destroyed, the trunks and branches dry up.
Each of these fungi can cause stem rot. The infection persists in the affected trunks and branches.
Control measures. Clean the ulcers to a healthy tissue, remove the tinder fruit bodies, disinfect the 3 lesion sites with% copper sulfate, cover the exposed wood with oil paint. Periodically spray bushes (in spring and autumn) with Bordeaux mixture.
Sea buckthorn fruit rot
The causative agent is a mushroom Monilia altaica. The affected berries brighten and become flabby, mucous, white-ocher pads of sporification are formed on the surface. Over time, the berries darken and mummified.
Control measures. Remove infected berries and dried branches, spray the bushes before the leaves grow back and after flowering with Bordeaux mixture. With a strong manifestation of the disease, spray again in the fall, after picking berries.
And how to handle these shrubs from pests sea buckthorn fly? For this purpose, Karbofos, Confidor and Calypso are used.
