Abstract

An insecticide for preventing and controlling aphids and mites and a preparation method thereof, the insecticide comprises capsaicin, matrine, lupus toxin, nicotine and veratrol extract, and the specific preparation steps are: freezing and thawing Sophora flavescens After treatment, it is put into a plant crusher together with the peppers for crushing, and is added to a multi-functional extraction tank, heated and refluxed for extraction with alcohol, and the extract A and the slag are separated; , obtain extract B; mix extract A and extract B to obtain matrine and capsaicin concentrate; extract veratrol with alcohol at room temperature under ultrasonic-assisted conditions to obtain veratrol extract; mix ginseng and capsicum The aphid mites insecticide is obtained by mixing uniformly the vegetarian concentrate, veratrol extract, wolf toxin and nicotine. The advantages are: the preparation is composed of natural active substances, has rapid drug effect, long drug effect period, is environmentally friendly, and does not produce resistance to insect pests, especially has killing effect on aphids and pest mites.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticide for preventing and controlling aphids and harmful mites and a preparation method thereof. Background technique [0002] China is a large agricultural production country. In recent years, the pace of agricultural development has been accelerated, and the output of pesticides has also increased year by year. However, most of the pesticides currently used in our country are chemical preparations, and the large-scale use of chemical preparations is likely to cause pesticide chemical residues in agricultural and sideline products, and it is also easy to accidentally kill natural enemies of insect pests and make insect pests resistant to pesticides. With the development of science and technology, the active substance extracts in natural plants are processed into botanical pesticides of insecticides, which have the advantages of environmental friendliness and generally low toxic...
