Problems solved by technology

Most of the insect eggs are concentrated on the back of the leaves, which are yellow; before the third instar, they are often clustered together, and timely removal of insect leaves can reduce the damage, but the efficiency is low
Drug control can be sprayed with 1000 times of 80% dichlorvos emulsion or 3000 times of 50% phoxim emulsion, which cannot be prevented and the drug residues are serious

Embodiment Construction

[0009] An insecticidal composition for preventing and treating willow caterpillars, prepared from the following components by weight: 2 parts of etofenproxil, 2 parts of trichlorfon, 2.6 parts of bean root, 3.7 parts of castor bean, and 5.1 parts of nuxychon 5 parts of Fangji, 1.6 parts of mulberry leaves, 7 parts of Polygonatum, 1.7 parts of Adenophora, 4 parts of Artemisia argyi, 2.6 parts of Glauber's salt, 1 part of Hemlock, 4 parts of Baibu, 5.1 parts of Cnidium.

[0010] Preferably, the traditional Chinese medicine components are respectively decocted with water five times the weight of the traditional Chinese medicine to obtain a decoction liquid, which is mixed uniformly, and then mixed with etofenprox and trichlorfon to obtain an insecticidal composition.

[0011] Preferably, when applying, the insecticidal composition and water are diluted at a weight ratio of 1:300 before use.

[0012] Example of use

[0013] When preparing, by weight, take 2.6 parts of bean root, ...

Abstract

The invention relates to an insecticidal composition for caterpillar control. The insecticidal composition is prepared from following components by weight: 2 parts of ethofenprox, 2 parts of dipterex, 2.6 parts of asiatic moonseed rhizome, 3.7 parts of castor seed, 5.1 parts of nux vomica, 5 parts of mealy fangji root, 1.6 parts of mulberry leaf, 7 parts of solomonseal rhizome, 1.7 parts of coastal glehnia root, 4 parts of artemisia argyi, 2.6 parts of crystallized sodium sulfate, 1 part of cicuta douglasii, 4 parts of stemona root and 5.1 parts of common cnidium fruit. The insecticidal composition has good control effects for salix matsudana caterpillars and can play a role combining prevention and treatment.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition for preventing and treating willow caterpillars. Background technique [0002] Willow is an important economic crop in the Huaihe River Basin. It is mainly used as raw material for willow weaving. However, in the growth process of willow, caterpillars are a very harmful pest. Willow caterpillars are commonly known as golden caterpillars and poisonous caterpillars. There are many occurrences in willow fields all over the country. There are poisonous hairs on the larvae, which can cause redness, swelling and pain in the human body. It is mainly caused by larvae, which is one of the main pests of willow. Willow caterpillars mostly gather on the back of the leaf to feed on the mesophyll. The leaf surface shows blocky transparent spots. Adults are phototaxis and lay eggs on the back of the leaf. After 5-7 peelings , form thin cocoons and pupate in st...
