Processing cherries in the spring for diseases and pests is needed not only for treatment, but also for prevention. To carry out the processing correctly and without harm, you need to know what exactly and in what time frame the plant should be sprayed.
When can you spray cherries in the spring against diseases and pests
When processing fruit trees, you should always rely not on specific dates, but primarily on the weather. Spraying times depend on temperature conditions and on a specific region.
When to treat cherry pests in spring
From pests, the tree begins to be treated with the onset of the first warming. Insect larvae wake up in the ground and fallen leaves - accordingly, it is advisable to carry out the first treatment at this moment. Usually the tree is sprayed until green buds and buds appear, and then the procedure is repeated several times during the spring and summer.
The first treatment is carried out immediately after the spring warming.
Terms of processing cherries in the spring from diseases
Treatment for diseases is also carried out with the onset of heat, but before the onset of sap flow. You need to focus on temperature indicators - you can spray a tree from fungal diseases at a temperature of about 5 ° C above zero.
As a rule, the right time comes in early or mid-March in the middle lane and in early April in Siberia.
How to treat cherries in spring from diseases and pests
Wood treatment products can be divided into 2 categories - chemical and homemade. The former demonstrate greater efficiency, however, many gardeners are afraid to spray fruit trees with chemicals and therefore prefer folk remedies.
Folk remedies for sprinkling cherries in spring
There are several simple homemade preparations that really help protect trees from diseases and pests:
- Wormwood infusion - 400 g of dried herbs are bred in a bucket of water and the trees are treated with the resulting product.
- Infusion of onions - 600 g of chopped onions are stirred in a bucket of water.
- Soap solution - 100 g of laundry soap, rubbed with fine shavings, must be dissolved in 10 liters of water.
- Citrus Peel Soap - Add a handful of dried orange or lemon peels to a regular soapy solution.
Some home remedies work well
Folk remedies show a fairly high efficiency if they are used for prophylaxis and with weak damage to the tree by pests and diseases.
Preparations for processing cherries in the spring from diseases and pests
If the tree is seriously infected, or there is no desire to prepare folk remedies on your own, you can use proven universal preparations.
For fungal diseases, they are most often used:
- copper or iron vitriol - the remedy is effective against scab, most fungi, mosses and lichens;
- urea - the drug is effective against most fungal diseases;
- copper oxychloride or Scor, Nitrafen and Kuprozan - remedies help against all fungal diseases of cherries;
- bordeaux mix - the drug helps not only against diseases, but also against pests.
In addition to fungicidal preparations, there is a list of popular insecticides for cherry pests:
- Karbofos - the drug is effective against cherry flies, aphids, slimy cherry sawfly and other insects.
- Fufanon - a remedy used to protect against aphids, common slimy sawfly, dangerous cherry fly, weevil and hawthorn.
- Inta-Vir - the drug helps against hawthorn, cherry flies, as well as aphids and moths.
- Iskra-M and Iskra-Bio - complex preparations can be used to combat any pests in the garden.
The exceptions are Iskra-Bio and Iskra-M, which are recommended for use throughout the entire growing season.
Chemicals are more effective in treating cherries than home remedies
Rules for spring processing of cherries from diseases and pests
For the safe processing of cherries and to preserve its health, it is necessary to know during what period of the growing season the treatment with certain preparations should be carried out. Untimely spraying can harm flowering and fruiting, so you need to approach the procedure carefully.
How to process cherries before flowering
In the middle of spring, shortly before the cherry blossoms, a complex treatment against pests and diseases is carried out. To sprinkle cherries before flowering, apply:
- Bordeaux liquid, Nitrafen, vitriol (iron or copper), Topsin-M - preparations protect cherries from moniliosis;
- Horus, Topaz and Topsin-M from anthracnose - before flowering, the tree is treated for the first time, then the treatment must be repeated three times per season;
- Nitrafen - for scab, the tree is treated for the first time at the very beginning of spring, shedding soil, and the second time it is sprayed over the crown before flowering;
- Corsair or Karbofos - cherries are processed from a cherry weevil shortly before flowering, then, if necessary, spraying is repeated.
It is necessary to process cherries in the spring on a pink bud, before the flowers open, so that the preparations do not damage the pollination process.
Is it possible to spray cherries during flowering
During the flowering period, cherry processing is considered undesirable. Most insecticidal and fungicidal products pose a threat to insects that benefit and are responsible for pollination in the garden, therefore, the treatment can negatively affect the future harvest.
A flowering plant can only be sprayed with safe preparations and in exceptional situations.
In exceptional cases, you can spray cherries during flowering against aphids, weevils, scab or coccomycosis, using relatively safe drugs. These include:
- Fitoverm, Iskra-Bio and Iskra-M, Akarin - non-toxic substances of biological origin;
- homemade ash and soap solution;
- a garlic or tobacco solution to help get rid of pests.
If spraying cherries during flowering can still be postponed to a later date, then it is better to wait with processing.
How to process cherries after flowering
At the end of flowering, the fight against diseases and pests of cherry trees continues.It is recommended to spray the cherry after flowering:
- from aphids - means Decis and Bi-58, as well as Inta-Vir, Iskra and homemade infusions based on onions, garlic, tobacco and ash, help well;
- from moniliosis - it is allowed to use copper oxychloride, Bordeaux liquid, Kuprozan and Tsineb, Skor and Topsin-M;
- from clotterosporia - the cherry is sprayed with Bordeaux liquid after flowering, if necessary, repeat the procedure after 2 weeks;
- from anthracnose - treatment with Topaz, Horus and Polyram has a good effect;
- from scab - it is best to use Nitrafen.
It is necessary to process cherries after flowering from pests and ailments twice or three more times - this will consolidate the effect of previous spraying and will have a preventive effect.
After flowering, cherries are treated for diseases a couple more times.
How to process cherries on a green cone
The green cone is called the period in spring when the buds on the fruit trees are just beginning to bloom, and green leaves are slightly visible from them. During this period, spores of fungal diseases and pest larvae massively revive, therefore, it is necessary to process cherries in early spring for high-quality protection.
During the green cone period, cherries are usually sprayed:
- Bordeaux liquid 3% from fungal diseases;
- Fufanon and Sumition from cherry moth;
- Lepidocirum from most garden pests;
- solution of ferrous sulfate 5% from fungal diseases;
- Soon from coccomycosis;
- Nitrafen for scab;
- Decis or Spark from aphids;
- Aktara, Karbofos, Metathion and Metaphos from the shoot moth.
Early cultivation of cherries in the garden allows you to eliminate pests and fungi or reduce their population. Thus, the subsequent control of pests and diseases is greatly simplified.
How to process cherries for the prevention of diseases
It is necessary to spray cherries in spring even if pests and fungi are not visible on it. Good prevention reduces the risk of cherry diseases - preventing diseases is always easier than treating an affected tree.
For prevention, it is customary to use:
- fungicidal solutions of general action - Bordeaux liquid and copper sulfate, Nitrafen and Skor;
- insecticidal preparations for the most common pests - Karbofos, Aktaru, Fufanon, Lepidocir;
- lime solution - processing the trunk circle and the trunk itself will help prevent most fungal diseases;
- potassium sulfate - if you water the soil around the trunk with water and fertilizer in the spring, the tree's immunity will become higher.
Prevention of ailments plays an important role in cherry care

How to process cherries so that there is no empty flower
If the rules of agricultural technology are violated, the cherry often becomes a barren flower, that is, it gives abundant flowering in the spring, but at the same time it almost does not form ovaries and does not bear fruit. This can happen when damaged by pests and diseases, but there are other reasons.
To improve the formation of ovaries, it is necessary to monitor the composition of the soil.
The quality of flowering and fruiting is influenced, among other things, by the composition of the soil. Cherries need a neutral or slightly alkaline soil - if the soil is too acidic, the tree can become barren. You can find out about soil acidification by the following signs:
- slow growth of a young tree - less than 20 cm per year;
- a small number of branches on the branches;
- premature fall of flowers;
- microcracks in the bark.
In order to change the composition of the soil for the better, you can use lime or dolomite flour - the funds must be added to the soil in the near-trunk circle.
Empty flowering can also occur due to a lack of boron in the soil. In this case, you need to process the fruit tree with a solution of boric acid - 10 g of the drug is diluted in a bucket of water. Spraying is carried out before flowering and immediately after it, the formation of ovaries then improves.
How to spray cherries in the spring to improve the yield
Even in the presence of pollinating trees on the site, the yield of fruit crops is not always high. For example, a cold and cloudy spring can affect the volume of fruiting, bees and bumblebees fly reluctantly in such weather, pollination is incomplete.
To improve the quality of pollination and yield, a honey solution can be used. About 150 g of natural honey is bred in a bucket of water, and then flowering trees are sprayed with this composition. Bees, attracted by the sweet smell, begin to pollinate the tree more actively, respectively, and the yield becomes higher.
To improve yields, you can artificially attract bees to the garden.
Spring cherry processing rules
When spraying cherries in the spring from pests and diseases, you must adhere to several rules:
- Treatment with garden chemicals is carried out only in compliance with safety rules. It is necessary to spray fruit crops in a respirator and mask, tight gloves and closed work clothes. Do not allow the solution to get into the eyes or on the skin, and children and pets must be removed from the site.
- It is necessary to spray trees in dry weather at a positive temperature. There will be no benefit from processing in the rain - preparations to protect against pests and diseases will be washed off the plant.
- When processing cherries during flowering, you need to carefully study the instructions for using the selected product and make sure that it does not harm beneficial pollinating insects.
- It is necessary to process fruit trees several times during the spring. Usually, for diseases and pests, the plant is sprayed three times - before flowering, immediately after it and a couple of weeks later to achieve the maximum effect.
Treatment for diseases is carried out in dry and warm weather.
Conclusion
The processing of cherries in the spring from diseases and pests is carried out in several stages. For treatment and as a prophylaxis, the tree is sprayed with special agents both before and after flowering - this allows you to achieve better results.
