Among the most common diseases and pests of cherries are European cancer, phyllosticotosis, chalcosporosis, tuberculosis, chlorosis, monilial burn, cherry aphid, slimy sawflies, herbal bugs and cherry pipeclover. Without timely protective measures, the harvest can be completely destroyed, and the trees themselves are at risk of dying.
On this page you can read a description of diseases and pests of cherries, as well as learn about treating trees in the garden.
Cherry diseases and their treatment: photos and control measures
Common or European cancer
The causative agent is a mushroom Nectria galligena. The bark of the branches and shtambov grows brown and dries out, longitudinal cracks appear, under which are marked deep ulcers with raised edges from the influx of callus tissue. Gradually, the ulcers deepen, and the affected branches dry out. The infection persists in the wood of the branches.
The description of this cherry disease is illustrated in the photo:
Control measures. Cut out the affected branches, disinfect wounds and mechanical damage with 1% copper sulfate, cover with oil paint.
Perform spring sprays with an 1% Bordeaux mixture or its substitutes.
Shrinking branches, or tuberculosis
The causative agent is a mushroom Tubercularia vulgaris causes necrosis of the cortex. The affected bark of the branches dries out; numerous orange-red pads of fungus sporulation, which turn brown with time, form on its surface. Spores constantly re-echo neighboring branches. The infection persists in the cortex of the affected branches.
Control measures. Timely cut the affected branches, disinfect wounds and mechanical damage with 1% copper sulfate, smear it with oil paint. Processing of cherry trees in the garden from this disease is done in the spring, before the leafing of 1% Bordeaux mixture or its substitutes (HOM, Abigapik).
Brown spotting, or phyllostiktosis
The causative agent is a mushroom Phyllosticta prunicola, causes the formation of round, ocher-brown spots with dark narrow border on the leaves. Over time, the affected tissues fall out, leaving holes.
As seen in the photos, with massive development disease leaves cherries turn yellow and fall prematurely:
The infection persists in the affected plant remains.
Control measures. Remove plant residues, spray the trees immediately after 1 blooms with the Bordeaux blend or HOM, Abiga-Peak. Repeat spraying as needed after picking.
The causative agent is a mushroom Cercospora cerasella. Numerous rounded, up to 2-3 mm in diameter, spots of red-brown color with a dark purple border are formed on the leaves. Over time, holes remain in the leaves. Affected leaves turn yellow and fall prematurely. Infection persists in plant debris.
Control measures. Collect and remove plant residues. To combat this cherry disease, spray trees immediately after flowering and after harvesting 1% Bordeaux mixture or its substitutes.
How to process cherries for other diseases
The causative agent is a mushroom Ganoderma applanatum causes decay of wood, from which trees easily break. Infection occurs at the base of the trunk, from where the mycelium spreads upwards. Fruit bodies are perennial, flat, sessile, often arranged in a tile-like manner, with an upper grayish-brown, furrowed surface, smooth, or covered with brown patina. The infection persists in the affected wood.
Control measures. Before treating the cherries for this disease, cut off the corpus spirits. Then disinfect 1 cuts and slices with copper sulfate, coat them with oil paint. Remove and burn dried trees along with roots. Perform annual spraying of gardens before leafing 1% Bordeaux mixture or its substitutes.
The causative agent is a mushroom Monilia cinerea. In the spring, during the flowering period, petals turn brown and dry, fruit ovaries and young leaves. Whole branches are affected, the death of the cortex is often observed, and the disease further causes fruit rot. The infection persists in the affected bark of the branches and overwintered fruits.
Control measures. Spray the trees before the 1 buds are blooming with Bordeaux mixture or its substitutes.
These photos show measures to combat diseases of the cherry:
Repeat sprays immediately after flowering at the first symptoms of a monilial burn with the same preparations.
Uniform yellowing of the leaves between the veins is associated with a strong deficiency in the supply of nutrients to young growing leaves. The cause may be freezing and bark dying, or the spread of rot.
Pay attention to the photo - during the development of this disease on the cherry, browning and dying of the leaves, as well as drying of the branches are observed:
Control measures. Promptly identify the cause of leaf chlorosis. In case of freezers, disinfect 1 cracks with% copper sulphate and smear it with oil paint. When spreading tinder or cancer, cut off fruit bodies - they harm bark and wood.
Cut out the drying branches. For the purpose of prevention, spray the trees annually, before the bud blooming of 1% Bordeaux mixture or its substitutes.

Pest control cherries: photos and how to handle trees
Aphid cherry (Myzus cerasi) - Insect length 2-3 mm, black, feeds on young growing leaves of cherries and cherries. The larvae feed on the juice of the kidneys, and then the leaves and shoots. The leaves are twisted, the shoots are deformed. During the season several generations of the pest develop. It causes the greatest harm to trees in June - July. In autumn, females lay wintering eggs near the kidneys. The colony
Control measures. Before treating cherries from pests, you need to cut off the damaged aphids tops and leaves. Spray the trees immediately after flowering at the appearance of the first colonies with the drugs Kemifos, Fufanon. If necessary, repeat spraying in the summer, respecting the waiting time of drugs.
Sickle Cherry Mucus
Sawfly cherry slimy (Caliroa cerasi) - shiny black insect length 5-6 mm, with transparent wings. The larvae are greenish-yellow, 9-11 mm long, covered with black mucus, have a thickened front edge of the body. The larvae become covered with mucus and feed on the leaf tissues, skeletonizing the plastic sheet.
On one sheet can feed up to 10 larvae. Having completed development, the larvae go to the soil and pupate. The summer of the second generation of the pest is observed at the end of July - early August, the development of the larvae continues until the end of September, after which they go to the ground to winter.
Control measures. To treat cherries from these pests, spray the trees when the larvae appear in large quantities with the preparations Kemifos, Aktellik, Inta-Vir, Fufanon.
Cube Tubkovert (Rhynchites auratus) - weevil beetle of bronze-green color with golden glitter.
As shown in the photo, the larvae of these pests of the cherry are curved, yellowish, with a brown head:
Beetles come to the surface during cherry blossoms, feed on buds, flowers and fruit ovaries. Females gnaw the fruit and lay eggs on the fetal bone. Larvae bite into the bone and feed on its core. The fruits struck by the pipe-worm dry up.
Control measures. To combat these pests of the cherry, spray the trees immediately after flowering with one of the following preparations: karbofos, fufanon, kinmiks.
Herbal bug (Lygus rugulipennis) - beetle 5-5,5 long, mm, the base of the front wings leathery, dense, and the top - membranous, rear wings webbed. Color is greenish gray, rusty yellow. Adult bugs overwinter under plant debris, in spring females lay eggs on petioles and plant leaves.
Larvae and adult bugs feed on the sap of young leaves from both grass and woody plants. Bugs are found on stone, pome, berry and deciduous, forest species.
Control measures. Spray the trees during the mass appearance of bedbugs with one of the preparations: kemifos, fufanon, Inta-Vir, aktar.
