Botanical insecticide

Abstract

The invention discloses a botanical insecticide, which comprises the following active components extracted from sophora flavescens, tobacco, common monkshood mother roots, kusnezoff monkshood roots, a wormwood, ligusticum, nux vomica, quisqualis indica and croton: 55-70% by weight of matrine, 0.5-5% by weight of tobacco-alkaloid, and 25-44 % by weight of aconitine, ligusticum oil, brucine, potassium quisqualate and crotin. The insecticide belongs to an insecticidal and acaricidal pesticide, can be used for pest control of vegetables, fruit trees, crops and the like, the selected plants are naturally ubiquitous, can be degraded by microorganisms in the nature, have no injury or residues to crops, do not pollute the environment or agricultural products, do not kill natural enemies, have no teratogenic, carcinogenic and mutagenic hazards to mammals, have strong pest-killing effects, are efficient and safe, have good control efficiency and are low in cost. The botanical insecticide is particularly suitable for controlling citrus pests.

Description

technical field [0001] The invention relates to an insecticide, in particular to a botanical insecticide prepared by extracting active ingredients from various plants. Background technique [0002] Citrus is one of the most important fruits in southern China. It has high edible value and considerable economic benefits. It is mainly cultivated in the provinces south of the Yangtze River. In recent years, due to the warming climate and the long phenological period of citrus, there are many kinds of citrus pests, and the damage is becoming more and more serious. Pests that cause large losses include spider mites, scale insects, and citrus leaf miners. [0003] Most of the insecticides in the prior art are chemical pesticides, which have low drug efficacy and a long period of residual toxicity, seriously affecting the crop growth environment and the health of humans and animals. Pesticides are a special class of chemicals, which can not only prevent and control agricultural an...

AI Technical Summary

Problems solved by technology

High-efficiency and highly toxic pesticides are highly toxic and remain in the environment for a long time. When humans and animals eat food containing pesticide residues, they will cause cumulative poisoning

This type of hazard often takes a long time to accumulate before showing symptoms, and it enters the human body through the enrichment of the food chain, and it is difficult to detect in time. Therefore, it is generally not taken seriously by people, and this type of pollution has a wide range. , the number of people harmed is large, and in many cases, human beings themselves are poisoning themselves, so this kind of harm is more dangerous

[0004] Once pesticides enter the environment, their toxicity and high residue characteristics will have an effect, causing serious pollution of the atmosphere, water and soil, thus bringing harm to human health

When toxic pesticides are applied to crops, vegetables and fruit trees, the pesticides remaining on the surface of the crops, due to their strong fat solubility, can easily penetrate into the waxy layer of the crop epidermis, making it difficult to completely wash off
