How to spray cherries before, during and after flowering, before bud break: timing, calendar and processing rules

Processing cherries in the spring from diseases and pests is needed not only for treatment, but also for prevention. In order to carry out the processing competently 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 from diseases and pests

When processing fruit trees, you should always rely not on specific dates, but primarily on the weather. The timing of spraying depends on temperature conditions and on the specific region.

When to process cherries from pests in spring

From pests, the tree begins to be processed 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 very moment. Usually the tree is sprayed until green buds and buds appear, and then the procedure is repeated several times during 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 start 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 at the beginning or middle of March in the middle lane and at the beginning of April in Siberia.

How to treat cherries in the spring from diseases and pests

Wood preparations 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 spraying cherries in spring

There are several simple home-made preparations that really help protect trees from diseases and pests:

1. Wormwood infusion – 400 g of dried grass is diluted in a bucket of water and the trees are treated with the resulting remedy.
2. Onion infusion – stir 600 g of chopped onion in a bucket of water.
3. Soap solution – in 10 liters of water you need to dissolve 100 g of laundry soap, rubbed with small chips.
4. Soap solution with citrus peels – add a handful of dried orange or lemon peels to a regular soap solution.

Some home remedies work well

Folk remedies show a fairly high efficiency if they are used for prevention and with a 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.

From fungal diseases most often used:

• copper sulphate or iron sulphate – the remedy is effective against scab, most fungi, mosses and lichens;
• urea – the drug is effective against most fungal diseases;
• copper chloride or Skor, Nitrafen and Kuprozan – remedies help against all fungal diseases of cherries;
• Bordeaux mixture – the drug helps not only from diseases, but also from pests.

In addition to fungicides, there is a list of popular insecticides for pests for cherries:

1. Karbofos – the drug is effective against cherry flies, aphids, slimy cherry sawflies and other insects.

   

2. Fufanon – a remedy used to protect against aphids, a common slimy sawfly, a dangerous cherry fly, weevil and hawthorn.

   

3. Inta-Vir – the drug helps against hawthorn, cherry flies, as well as aphids and moths.

   

4. Iskra-M and Iskra-Bio – complex preparations can be used to combat any garden pests.

   

The exceptions are Iskra-Bio and Iskra-M, recommended for use throughout the growing season.

Chemical drugs 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 for the preservation of their health, it is necessary to know during what period of the growing season it is necessary to carry out the treatment with certain preparations. 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 cherry blossoms, a complex treatment is carried out from pests and diseases. To spray cherries before flowering, apply:

• Bordeaux liquid, Nitrafen, vitriol (iron or copper), Topsin-M – drugs 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 – from scab, the tree is treated for the first time at the very beginning of spring, spilling the soil, and the second time it is sprayed over the crown before flowering;
• Corsair or Karbofos – cherries are treated from cherry weevil shortly before flowering, then spraying is repeated if necessary.

It is necessary to carry out the processing of 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

Directly during the flowering period, processing cherries is considered undesirable. Most insecticidal and fungicidal products are dangerous for insects that are beneficial and responsible for pollination in the garden, respectively, the treatment may adversely affect the future harvest.

A flowering plant can only be sprayed with safe preparations and in exceptional situations.

In exceptional cases, it is possible to spray cherries during flowering against aphids, weevil, scab or coccomycosis, using relatively safe preparations. These include:

• means Fitoverm, Iskra-Bio and Iskra-M, Akarin – non-toxic substances of biological origin;
• homemade ash-soap solution;
• 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 the treatment.

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 cherries after flowering:

• from aphids – Decis and Bi-58 products help well, as well as Inta-Vir, Iskra and homemade infusions based on onions, garlic, tobacco and ash;
• from moniliosis – it is allowed to use copper oxychloride, Bordeaux liquid, Kuprozan and Tsineb, Skor and Topsin-M;
• from clusterosporiosis – cherries are 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 scabies – It is best to use Nitrafen.

It is necessary to process the cherry after flowering from pests and ailments two or three more times – this will consolidate the effect of previous sprayings and have a preventive effect.

After flowering, cherries are treated for diseases a couple more times.

How to process a cherry on a green cone

The green cone is the period in spring when the buds on fruit trees are just beginning to bloom, and green leaves are slightly showing from them. During this period, spores of fungal diseases and pest larvae come to life en masse, so it is necessary to process cherries in early spring for high-quality protection.

During the green cone period, it is customary to spray cherries:

• Bordeaux liquid 3% of fungal diseases;
• Fufanon and Sumition from cherry moth;
• Lepidocyrom from most garden pests;
• a solution of ferrous sulfate 5% from fungal diseases;
• Soon from coccomycosis;
• Nitrafen for scab;
• Decis or Spark from aphids;
• Aktara, Karbofos, Metation and Metafos from shoot moths.

Early processing of cherries in the garden allows you to eliminate pests and fungi or reduce their population. Thus, subsequent pest and disease control is greatly simplified.

How to process cherries for the prevention of diseases

It is necessary to spray cherries in the spring even if pests and fungi are not visible on it. High-quality 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 mixture and blue vitriol, Nitrafen and Skor;
• insecticidal preparations from the most common pests – Karbofos, Aktaru, Fufanon, Lepidotsir;
• lime mortar – treatment of the near-stem circle and the trunk itself will help prevent most fungal diseases;
• potassium sulphate – if you water the soil around the trunk with fertilizer in the spring, then the immunity of the tree will become higher.

Disease prevention plays an important role in cherry care

Cherry processing calendar for pests and diseases

The calendar will help you navigate the timing of processing cherry trees from diseases and insect pests:

How to process cherries so that there is no barren flower

If the rules of agricultural technology are violated, the cherry often becomes an empty flower, that is, it gives abundant flowering in the spring, but at the same time almost does not form ovaries and does not bear fruit. This can happen when affected 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 a barren flower. You can learn about acidification of the soil 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 trunk circle.

Empty flowering can also occur due to a lack of boron in the soil. In this case, it is necessary to treat 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 after that improves.

How to spray cherries in the spring to improve the harvest

Even with 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 fruiting volumes, bees and bumblebees fly reluctantly in such weather, pollination is defective.

To improve the quality of pollination and harvest, you can use a honey solution. About 150 g of natural honey is diluted in a bucket of water, and then flowering trees are sprayed with this composition. The 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

Rules for spring processing of cherries

When spraying cherries in the spring from pests and diseases, several rules must be followed:

1. Processing with garden chemicals is carried out only in compliance with safety rules. It is necessary to spray fruit crops in a respirator and mask, thick gloves and closed work clothes. Do not allow the solution to get into the eyes and on the skin, and children and pets must first be removed from the site.
2. It is necessary to spray trees in dry weather at a positive temperature. There will be no benefit from processing in the rain – preparations for protection against pests and diseases will be washed off the plant.
3. When processing cherries during flowering, you need to carefully study the instructions for using the chosen product and make sure that it will not harm beneficial pollinating insects.
4. It is necessary to carry out the processing of fruit trees several times during the spring. Usually, the plant is sprayed against diseases and pests three times – before flowering, immediately after it, and after a couple of weeks to achieve maximum effect.

Treatment for diseases is carried out in dry and warm weather.

Conclusion

Processing cherries in the spring from diseases and pests is carried out in several stages. For treatment and as a preventive measure, the tree is sprayed with special means both before flowering and after it – this allows you to achieve better results.
