As soon as the sun warms up and the summer cottage season opens, the first green shoots appear on the trees, shrubs - this is a signal sign for malicious plant pests. Aphid is one of the first to wake up. This is a small insect of very small size, but its number will literally strangle any young tree. In addition to the fact that aphids actively drink juice from young shoots, they are also a carrier of dangerous phytopathogenic viruses. And the third detrimental factor is the release of honeydew, which clogs the breath, disrupts the metabolism in the leaf integument and interferes with further development.

This dangerous pest is carried by ants. They use the metabolic products (honeydew) secreted by aphids for their own nutrition.

On a note! A large number of ants near fruit and ornamental plants is a sure indicator of aphid infestation.

In this article, you can find answers to such important questions - how to deal with aphids on fruit trees and how to treat trees from aphids.

To avoid a total aphid attack, it is advisable to follow these recommendations:

  • In autumn, as well as in early spring, it is necessary to remove the dead bark of trees, because this is a reliable shelter for the wintering of the pest;
  • A mandatory disinfecting procedure is carried out - the treatment of trees with lime (the exception is very young trees - you can burn the delicate bark, which is fraught with deep erosion of the trunk);
  • Weeding of young weeds near the hole with a plant is mandatory, in particular, the bedstraw is the greatest threat;
  • It is necessary to systematically pull out the shoots that form next to the adult plant;
  • Spraying with specialized preparations, starting from the second month of spring.

How to treat trees from aphids and ants: ready-made preparations

Aphids are a fairly common and aggressive pest, so there are a lot of chemical-based preparations from it. The most popular are:

  • Spark - this tool is used both for the garden and for indoor flowers. Influence on aphids of an enteric nature. It is mainly sold in tablet form. To prepare a solution, you must first dilute the concentrate (1 tablet per 1 liter of water), and then the true solution for use (filter and dilute the concentrate to 5 liters). Apply to the plant using a sprinkler (it is advisable to treat first of all the growing point and the youngest leaves). Spraying can be repeated after 20 days;
  • Aktara is a broad spectrum insecticide that attacks aphids with lightning speed. Literally after 30-40 minutes, the effect is noticeable (60% of the individuals die). This drug is presented in granules. The package should be divided into 2 times and used with an interval of 7 days. The drug is quite toxic, so you need to use a mask and gloves;
  • Trichopolum - the drug is sold in the form of tablets (20 pieces per pack). The main active ingredient is metronidazole. To prepare the mixture, you will need 10 liters of water and an insecticide package. It has an effect on the nervous system of the insect, paralyzing it;
  • Fufafon is an effective intestinal insecticide that comes in liquid form. Working solution - 2 ml of concentrated preparation per 2 liters of water. Used with an interval of 1.5-3 weeks;
  • Jaguar is a drug that is supplied immediately in a diluted form (5 liters). The effect is quickly visible (2-3 hours after treatment). Fruit trees are watered with this insecticide.The mechanism of action on aphids - through the root, substances enter the leaves through the vessels, which become unsuitable for use by the pest. Validity period - about 1 month;
  • Commander - the insecticide is sold as a liquid concentrate (10 ml). This drug differs from others in that it infects aphids at all stages of development (from an egg to an adult adult).

For use, you need to dilute 1 ml in 10 liters of water. The action is immediate, but not long-term (1.5 weeks after spraying);
  • Shar Pei - the active ingredient is cypermethrin. The insecticide is one of the most toxic and fast-acting. It has a wide range of uses (except for fruit crops, it is used on vegetables). It is applied at least 4 times a season. After 2-7 days, the main effect is visible. The package (10 ml) can be divided into two uses and for every 5 ml of concentrate 10-15 liters of water are required.

Aphids on trees are different

Important! All chemical insecticides should be used in dry, calm weather, early in the morning or on a cool evening, with protective equipment - gloves, mask, glasses.

Folk remedies against aphids

Insecticides made at home and from natural ingredients are not as effective as chemical ones. But the fight against aphids on fruit trees in this case becomes much safer and more economically profitable. Basically, such solutions are used for prophylaxis.

Soap spraying

How to deal with leaf rollers on fruit trees

You don't need much for this method: water, soap and a spray bottle. Preparing a soap insecticide is very simple: rub 300-400 g of laundry soap on a grater or replace it with a more effective soap - tar (200 g). Dilute crushed soap in 10-15 liters of water. You can also use liquid soap, it dissolves easily and only 100 ml is required. Treating trees from aphids and ants is enough once every three weeks.

Important!All soap solutions should only be used chilled.

Herbal infusions

  • Garlic - chop 100-200 g of garlic and infuse for 7 days in 1.5 liters of water under a tightly closed lid. Dilute the concentrate in proportions of 30 ml to 10-15 liters of water. Spray at the first appearance of aphids;
  • Onion - 40 g of chopped onion with husk insist for 8 hours in 1 liter of water. Spray the plants every 2 weeks;
  • Chamomile - buy chamomile medicinal at the pharmacy and infuse the powder of the plant during the day with the addition of 2 liters of water. Preferably use immediately after preparation. Valid for 1-1.5 weeks.
  • Dandelion - 0.5 kg of leaves and 200 g of roots to insist in 15 liters of water for about 10-15 hours. Can be replaced with dried plants.

Any solution, even if it is of natural origin, in high concentration can be toxic to both humans and the treated plant.

Folk methods of struggle

Chemical substances

One of the most effective chemicals is common ammonia. It is very effective in the fight not only against aphids, but also against its carriers - ants. The spectrum of action of this substance is unlimited, processing can be carried out on fruit trees, shrubs, vegetables, fruits, ornamental plants, indoor plants.

The recipe is simple: 10-15 ml of ammonia per 1 cold water.In order for ammonia to better adhere to the surface of the leaves, you need to add tar soap and use immediately, since ammonia is a volatile substance. One procedure will require 10 liters of working solution (it is not necessary to spray everything, the remainder can be poured under the root, which will serve as a good fertilizer). You need to process it every two weeks, and as a preventive measure - once a month. You can start using from early spring and all summer (especially in June, when aphids are extremely active)

Advice! Particular attention should be paid to the inner side of the leaf, since the main breeding center is localized there!

Milk and iodine in combination work deadly against aphids. In addition to insecticidal effects, the solution has fungicidal properties (protects plants from the effects of phytopathogenic fungi). In order for the processing to be of high quality, you need to choose a calm day and preferably evening time.

Chemical form wrestling

Recipe: add 20 ml of iodine to 200 ml of warmed milk, shake well.

It is important to know! The solution acts only on adult insects (adults) and larval stages, and the egg shells are not destroyed. Apply after every rain.

Bordeaux liquid is in third place, does not have a direct insecticidal effect on aphids, but protects against concomitant diseases of a fungal and bacterial nature, which are provoked by a pest.

It is not difficult to prepare a solution: you need to take equal parts of copper sulfate (100 g) and lime (100 g), dilute these two substances separately from each other. Water for lime and vitriol is also needed equally - 5 liters and 5 liters. Next, you need, constantly stirring lime, introduce vitriol (on the contrary, you cannot!) And bring to a uniform color (pale blue). You need to use protection 4 - 6 times a season, from early spring to autumn.

To summarize all of the above, aphids should be actively combated and carried out regular prophylaxis. In addition to these methods, there are many ways and their variations to prevent plant damage by aphids. If you follow simple recommendations and visually inspect the trees in the garden, the global problem with a malicious pest and its carrier will disappear.
