TOP 10 most dangerous garden pests
Dangerous pests Colorado beetles
Famous potato lovers are the Colorado potato beetle and its larvae. Dangerous pests also like to feast on the leaves of tomatoes, eggplants and other nightshade crops. One larva eats up to 5 leaves per week. And if there is a whole invasion of beetles, then sowing potatoes may completely lose their tops.
For the fight, chemicals such as Commander or Spark are used. And if there are few insects, then folk remedies are used (a decoction of wormwood, clover or garlic). Also beetles and their larvae are collected by hand.
Despite the fact that slugs are slow mollusks, they can devour plants so that only one "skeleton" remains of them. Enveloping the leaves, mucus prevents young shoots from developing.
Fighting slugs is not difficult. They do not tolerate salt, pepper and ammonia. When there are too many of them, preparations containing metaldehyde can be used.
Aphids reproduce rather quickly. It draws sap from the leaves of plants and poisons them with a poison that causes disease and further death. To combat it, there are many folk remedies. Plants are treated with soapy water or onion infusion. With small accumulations of aphids, it is simply washed off with water.
Dangerous pests Whiteflies
It hides on the inner parts of the leaves, and reaches no more than 5 mm in length. Therefore, it is quite difficult to find it. Whitefly feeds on plant sap. It secretes a sweet liquid that can cause diseases such as powdery mildew and gray mold.
If the insect has just appeared in the garden, then folk remedies are suitable for the fight. For example, a solution of tar soap. But if they have already attacked half of the crops, then insecticides cannot be dispensed with (for example, Actellik).
This butterfly prefers flower nectar, and its caterpillar loves potatoes, tomatoes and other crops, but the most favorite is cabbage. You can destroy the cabbage scoop with pyrethroid insecticides, which in their composition are close to the substances secreted by plants for pest control (Antigusenem, Zeon).
Both adult ticks and its larvae can harm plants. They entangle the leaves and suck the juice out of them. If a spider mite has wound up on plantings, then they are treated with soapy water (40 g of soap per 10 liters of water) and, if possible, are protected from healthy crops. For processing, a solution of tobacco is also suitable, the smell of which the tick does not tolerate.
The invasion of these pests begins in the spring. You can destroy them with chemicals (Aktara, Aktellik). But if the use of chemicals is not suitable, then you can try to destroy them with a soap-ash solution. Plants are treated with a homemade drug every 5 days.
Dangerous pests Thrips
The length of black thrips is no more than 1.5 mm, so they can be mistaken for just a speck. In addition, they settle on the reverse side of the leaf and it is very difficult to find them. Folk remedies against them are practically powerless. They can only help at the initial stage of the lesion. It is better to use insecticides (Fitovem, Actellik).
Medvedka can be found by the passages that it digs in the soil. It is quite difficult to deal with it, since the insect can fly and if you destroy it in your area, it will fly from the neighboring one.Traps made from honey and beer or eggshells and butter, which are laid out between the rows of plants, can help.
This is the larva of the click beetle that attacks potatoes and carrots. To combat it, folk remedies (potassium permanganate, nettle infusion) or chemistry (Prestige, Bazudin) are suitable.
