Aphids on cherries: how to get rid and how to process, drugs and folk remedies

Cherry aphid is a common garden pest that feeds on the juice of young leaves and shoots, which leads to the loss of foliage on trees, followed by the death of the crop. How can you get rid of aphids on cherry trees? There are chemical and biological preparations, folk remedies. Proper use of them will save the crop, save and protect trees from harmful insects.

Causes of aphids

Cherry aphid exists in the form of: larvae, wingless, winged, heterosexual individuals. Over the summer, aphids give several generations.There is an overpopulation of aphids in the living space, and in autumn many winged females are born, which fly over long distances in order to capture new places to create colonies.

If a colony of aphids that has captured trees in a garden plot is not removed during the summer, they will lay wintering larvae on young shoots near the buds, and in the spring they will begin to multiply with renewed vigor, capturing new trees, bushes and herbaceous plants (cucumbers, tomatoes, peppers).

Signs of tree damage by aphids

Thousands of aphid species are known. Black cherry aphid, except for cherries, affects stone fruits: plum, apricot, peach. The first sign of aphids capturing cherries is the appearance on young shoots, buds, blossoming leaves of brilliance - this is a sweet honeydew that aphids secrete as a result of their vital activity. The aphid does not eat the leaves, only sucks the juice. The leaves, losing moisture, curl up, dry out, aphids move on to other leaves.

The appearance of ants on trees is another sign of the appearance of aphids; ants eat the sweet honeydew, they guard the aphids and carry them to other trees. On the paths of ants you can find anthills. Ant control is a must in the fight against aphids.

To save trees and prevent the spread of aphids throughout the garden plot, aphids are fought with all available methods and means, without wasting time.

Insect pest control methods

There are many ways to deal with aphids:

• at the initial stages of the appearance of aphids, a mechanical method of dealing with the use of techniques and devices that prevent individuals from spreading throughout the garden is suitable: manual collection and disposal of branches and leaves, glue and grass traps;
• technological method of struggle includes the use of modern technology, tools, techniques: failure of aphids with a strong jet of water, the use of sprayers, pumps, fumigation with various compositions;
• chemical pest control involves treating trees with various fungicides;
• biological method is the use of biological preparations and natural enemies of pests;
• folk methods - the use of skills and improvised means, bactericidal and phytoncidal properties of surrounding plants, knowledge accumulated by gardeners for a long time in the fight against insects.

Competent and timely application of any method or set of measures helps to get rid of the aphid invasion. How to save the garden from pests, which way to choose to ensure he althy plant maintenance and get a high yield, is for gardeners to decide.

Mechanical

At the initial stages of seeding by larvae and female aphids, young shoots and leaves can be cut off and disposed of.

In the fight against ants (protectors and carriers of aphids), glue garden traps are used that prevent the movement of ants along the trunk of cherry trees.Traps are sold in specialized stores. Cultivating the soil of garden plots, timely removal of weeds help in the fight against pests and plant diseases.

Herbal traps are homemade from fresh grass, which is placed in a bowl with a high rim and sprinkled with sweet water.

Biological method

Destroy aphids without the use of toxic drugs will help ladybugs that feed on adults and aphid larvae. Plants will help attract ladybugs to garden plots: coriander, lovage, dill, parsley, fennel, calendula.

Live biomaterial in the form of ladybugs or their larvae can be purchased at pet stores and planted on aphid-infested trees.

Biological agent Fitoverm has a nerve-paralytic effect on adults through the digestive tract; the drug has no effect on the larvae.Processing is carried out according to the instructions, repeatedly, at dusk, preferably in wet weather (after rains). The drug completely decomposes in the light within 2-3 days, is not toxic to the environment.

The drug Akarin is identical in its properties, method of application to the previous drug.

Drug Iskra Bio: a bottle of 10 milliliters, the solution is prepared according to the instructions. The drug is highly effective, with heat + 25 ^{C and above, the efficiency is enhanced. Not addictive to pests. Plants are processed during flowering, setting and ripening of cherries.}

Technological

Technological processing methods include the use of simple folk technologies and modern achievements in technological processes and equipment.

Easy technologies include an elementary way to flush aphids and their larvae with a powerful jet of water.The land in the crown washout area is treated with chemicals or folk remedies, after which it is necessary to remove and dispose of all vegetation under the crown of cherry cherries.

Under the trees in a bucket they kindle pieces of rubber tires that emit acrid smoke - aphids and larvae die from it.

There is modern equipment that forms fine mixtures of cold or hot steam with chemical or biological preparations.

There are specialized organizations that carry out disinfection activities, both for individuals and in large nurseries, using new technologies and equipment. They take into account all the factors and processing conditions, masterfully apply chemical and biological preparations.

Chemical method

Chemicals are used when time is lost and aphids have infested most of the cherry branches. Chemical preparations are selected depending on the timing of the treatment, goals, areas of infection, expected results.

1. Spark preparation: dilute 1 tablet in 10 liters of water and sprinkle on the cherry tree during bud swelling or leaf opening.
2. Kinmiks preparation: 2.5 milliliters of the preparation is diluted in 10 liters, 4 liters are spent on a large tree. Aphids can be poisoned with this solution after flowering.
3. Drug Spark Gold: 40 grams diluted in 10 liters of water, solution consumption - 2-5 liters per tree, insects die within 2 days. The drug of prolonged action, term - 25 days, protects the shoots that appeared after treatment.
4. Preparation Iskra-M from caterpillars (also effective in the fight against aphids): 5 milliliters diluted in 5 liters of water, consumption per tree - from 2 to 5 liters, depending on the age of the tree and seeding. Fast acting.

Folk remedies for insect control

Modern chemical and biological preparations for the treatment of plants from diseases and pests appeared in the middle of the 20th century, with the development of chemical industries and biotechnology. There are many folk remedies that people used to protect their gardens and orchards in the past. All fungicides, pesticides, biological products contain substances of natural origin, obtained or derived by artificial methods.

Therefore, when using folk remedies, it is necessary to observe the concentration and dosage of the preparation of infusions, decoctions, solutions, since they can not only kill harmful insects, but also destroy trees.

Ash

Wood ash contains alkaline earth metal s alts; an aqueous extract of ash is called lye, due to the content of alkali metal s alts. Lye is soapy to the touch, has bactericidal properties.A solution of lye in water is enriched with additional substances that have the properties of fungicides.

Preparation of an ash solution with potassium permanganate (potassium permanganate):

• 2 cups of wood ash are poured into 10 liters of hot water, mixed well to dissolve the lye in the water;
• potassium permanganate is added to alkaline water - ½ coffee spoon, mix well;
• solution should become a rich pink color; a liquid with a high content of potassium permanganate (dark beet color) will burn the plant - such a solution must be diluted with water;
• strain the solution and spray the trees.

Preparation of the ash solution with soap and vinegar:

• 300 grams of ash is poured into a bucket, poured with 3 liters of boiling water, mixed and infused for a day;
• add 2 tablespoons of planed tar soap, mix, dissolve the soap;
• add 7 liters of water, mix, filter, add 2 tablespoons of 9% table vinegar (to neutralize the excess alkalinity of the solution so as not to burn the tree branches).

This solution is sprayed on cherry trees before flowering and 2 weeks after flowering.

Garlic

Garlic belongs to phytoncidos - its arrows emit phytoncides into the air, which have bactericidal properties, which repel pests. Gardeners plant plots around apple trees, cherries, plums with perennial garlic, which protects the trees from insects, including aphids. Garlic practically removes all pests from the area where it grows.

Infusion of garlic is prepared as follows:

• 10 liters of warm, not hot water is squeezed out, using a manual garlic press (garlic crusher), 50 grams of garlic, mixed;
• insist day;
• filter through a canvas cloth, wring out;
• Sprinkle cherries with the solution.

Dandelion

May and June are the months of abundant flowering of dandelion, with its help you can fight aphids. Fresh dandelion leaves or roots are good for this.

Dig up 300 grams of roots or pluck 400 grams of fresh leaves, chop the roots, cut the leaves and brew in warm (not higher than 40 ^{C) water, leave for 3 hours, filter and process sick tree.}

Celandine

Celandine - a plant with which you can successfully get rid of harmful insects. Celandine is harvested in May, during flowering (they are torn entirely under the root) - at this time, the celandine has a greater bactericidal properties. It must be remembered that the whole plant is poisonous.

The grass is dried in the shade, in a well-ventilated area. Dried grass is ground into powder and pollinated by aphid-infested branches and cherry shoots. Dry celandine powder sticks to sticky leaves, celandine toxins penetrate the leaf juice, aphids suck out the poisoned juice and die.

You can make an infusion from celandine: 3 kilograms of fresh plants are crushed and brewed with boiling water (10 liters), infused for 2 days or boiled for half an hour. You can brew dry celandine, while taking 800 grams of previously harvested celandine for the same volume of water.

Soap solution

A solution of 72% laundry soap acts as a contact fungicide (the high alkali content in the soap solution forms a protective alkaline film with a powerful bactericidal effect). If you prepare a soap solution in a decoction of yarrow, you get a preparation of combined action: contact and systemic, due to the bactericidal properties of yarrow.

Preparing a soapy solution with yarrow decoction:

• 800 grams of dried grass is ground, poured with 10 liters of boiling water, insisted for 2 days (or boiled for half an hour);
• decoction or infusion is filtered through gauze;
• grate ½ a bar of laundry soap, pour into a bucket of infusion, stir until the soap is completely dissolved;
• Spray seeded with aphids branches with a ready-made solution.

Preparing a soap solution in water:

• grate a piece of household or tar soap;
• dissolve the soap shavings in 10 liters of warm water, mix well, let the soap dissolve;
• spray the infected trees with the resulting solution.

How to handle properly

When processing cherry trees, it is necessary not only to correctly use preparations for disinfection, but also to remember the rules for processing trees and precautions against toxic effects on the human body:

• when carrying out chemical treatments, it is necessary to use a protective suit, rubber gloves, respirators, goggles;
• trees are treated in the early or evening hours, taking into account the humidity, in accordance with the instructions in the instructions, in order to maintain the insecticidal properties of the solutions;
• processing is carried out from the top of the crown of trees down, cherry trunks are processed, a piece of land around the trunk;
• equipment, protective suit and accessories must be washed with detergents;
• drugs are used depending on the state the tree is in (flowering, berry ripening, after harvest).

During flowering

During flowering, trees should not be treated with toxic preparations, as this will harm bees and other pollinators. The last time the treatment with chemicals is done 2 months before the ripening of the crop. During flowering, you can treat with Iskra Bio.

During fruiting

If necessary, during fruiting, trees are treated with biological preparations, since when chemicals are used, toxic substances penetrate into the pulp of the berry and have a toxic effect on the human body.

Biopreparations are used: Fitoverm, Akarin, Iskra Bio - they decompose in the light within 2-3 days.

After harvest

After harvesting, various chemicals can be used: fast-acting, long-acting, highly toxic.

Seasonal preventive measures

Preventive measures to ensure a he althy garden plot, and in particular cherry trees, must be carried out taking into account the seasons, the condition of the trees, the presence or absence of diseases or pests in the past season.

Choosing a location for planting cherries in a sunny, ventilated area is essential for the growth of he althy trees without pests. Cherries are planted away from viburnum, hawthorn, as they attract aphids with their specific odors.

Maintaining a weed-free garden, proper agrotechnical work, preventive measures against pests create all the conditions for growing he althy trees.

Spring

Spring preventive measures include: agrotechnical impacts in the form of digging land under the canopy of trees, whitewashing trunks with preliminary cleaning of the bark, competent application of mineral fertilizers.

Planting around the trunks of garlic, coriander repels harmful insects; coriander tops are cut daily - this enhances the release of phytoncides. Calendula and saffron attract ladybugs.

Summer

Summer preventive measures: regular weeding, mulching of the land with needles, as it contains phytoncides, preventive treatment of trees with long-acting chemicals, in case of plant infested with aphids in neighboring areas.

Combating anthills in the garden plot with the use of drugs: Ant, Thunder and folk remedies, since ants are carriers of aphids.

Autumn

Autumn preventive measures: cleaning and whitewashing the trunks, cleaning around the stem land from fallen leaves, dry grass, digging the land. Crown formation, pruning of dry and thickened branches.

Competent and regular preventive measures create conditions for breeding he althy plants in the garden plot without diseases, pests and for obtaining consistently high yields.
