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

Abstract

The invention relates to an insecticidal composition for control of Salix integra caterpillar. The insecticidal composition is prepared from the following components by weight: 2 parts of ethofenprox, 2 parts of dipterex, 2.6 parts of Rhizoma Menispermi, 3.7 parts of castor bean, 4.2 parts of Strychnos nux-vomica, 5 parts of Agastache rugosa, 1.6 parts of mulberry leaf, 7 parts of Polygonatum, 1.7 parts of Coastal Glehnia Root, 4 parts of folium artemisiae argyi, 2.6 parts of Mirabilite, 1 part of tobacco leaf, 4 parts of Stemona japonica, and 4.2 parts of Cnidium monnieri. The insecticidal composition provided by the invention has good control effect on Salix integra caterpillar, and can plays 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 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, during the growth 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 concentrate on the back of the leaves to feed on the mesophyll, and the leaves appear as massive transparent spots. Adults are phototaxis and lay eggs on the back of the leaves. After 5-7 peelings, Form thin cocoons and pupate in st...
