This is a fungus that affects the whole tree, but first of all it is visible on the leaves. Most often, spores winter in fallen leaves near the trunk, so regular cleaning is so important. Red-orange spots begin to gradually rise from the lower branches up, turn brown and become covered with a coating on the reverse side.
Breeders have bred varieties that are quite resistant to coccomycosis, so pay attention to varietal characteristics. When planting, avoid lowlands and moist soil, dig the soil in time. Sprinkle the cherry with a weak urea solution before flying around the leaves and with copper-based products - later. For treatment, the same copper-containing agents, Bordeaux liquid, fungicides Skor or Oksikhom are used.
This is a fungus that first affects the fruits so that they rot. It is very easy to lose sight of the first symptoms, because small pale spots appear on the berries. The rainy hot season contributes to the almost instant spread of anthracnose.
Take away the scavenger in time, dig up the soil and whitewash the trunk with the lower branches. Always disinfect all garden tools and enjoy gardening. For treatment, spray cherry three times with Polyram or similar drugs at intervals of 1.5-2 weeks.
The fungal pathogen overwinters in dry leaves, spreads in the warm season, and then mercilessly destroys the crop. The first symptom is yellow cracking spots on young leaves at the height of summer, when the temperature rises above 20 degrees.
To avoid scab is almost impossible without preventive measures. Leaky trunks, immediately remove dry leaves and branches, regularly introduce nitrogen and potassium fertilizing for immunity. For treatment, reusable treatment with copper-containing fungicides, such as Kuprozan, will be required.
This is a fungus that affects flowers, buds and young leaves during rains and cold snap. At first, everything looks as if the tree is just drying up. Many mistakenly believe that cherry burns in the sun or due to lack of moisture, and the problem is diametrically opposed.
For prevention, regularly thin out the crown, treat the trunk with garden lime with copper sulfate, and remove fallen leaves in time. Bordeaux fluid and copper-based fungicides are used for spraying. But first, you need to carefully cut and burn all the damaged branches, and treat the sections with an antiseptic.
If breasts of golden resin appear on cherry branches, it’s gum. The reasons can be very different - from an excess of moisture with fertilizers to mechanical damage to the branches. That is why it is important to immediately treat the wounds with garden varieties, clay with mullein or a solution of copper.
This is one of the fungal spotting characteristic of humid and warm regions. It is easy to distinguish, because small spots dry out and fall out, leaving holes behind. Mistakenly, klyasteriosis is confused with damage or pests, but insects are usually visible visually.
In the most advanced cases, the same spots appear on the fruits, and the branches become covered with ulcers. Always remove damaged branches immediately, treat the slices with a cook and spray the cherry with copper sulphate twice a year. For treatment, the same medications are used, but at a higher dosage.
The name indicates the symptoms of rust - cherry leaves are covered with bumpy orange spots. This is the fungus most commonly tolerated by conifers, so avoid this neighborhood. For prevention in the fall, spray trees with copper sulphate, and for treatment, use Skor, Khom or similar preparations.
