Biological pesticide

Abstract

The invention relates to a biological pesticide. The biological pesticide is characterized by being prepared from the raw materials in percentage by weight: 10-60wt% of cinnamyl aldehyde and toosendan fruit extracts, 8-10wt% of surfactant, 0.01-0.5wt% of chitosan, 10-50wt% of synergist and the balance of 95% ethanol, turpentine oil, lavender essential oil, ageratum oil and purple perilla leaf oil. According to the biological pesticide disclosed by the invention, the cinnamyl aldehyde and toosendan fruit extracts are taken as main active ingredients, so that the biological pesticide has non-toxic and harmless properties and has good volatility, and the disadvantages of pesticide residue increase and ecological environment destruction can be overcome; although the cost of the biological pesticide is slightly higher than that of chemical pesticides currently, the social benefit is better, the environmental pollution is less, and thus, the biological pesticide has a lot of advantages in the long run.

Description

technical field [0001] The invention relates to a biological pesticide and belongs to the field of biological control. Background technique [0002] Most of the insecticides and sterilizers in the prior art are chemical pesticides, which have low efficacy and a long period of residual toxicity, seriously affecting the crop growth environment and the health of humans and animals. It can not only prevent and control agricultural and forestry diseases and insect pests, but also cause harm to humans and livestock. And due to the large-scale application of chemical pesticides, air, water, soil and food have been polluted, and poisonous substances have accumulated in livestock and human bodies, causing poisoning and so on. [0003] According to literature reports, the utilization rate of pesticides is generally 10%, and about 90% of the remainder remains in the environment, causing environmental pollution. A large amount of pesticides volatilize into the air, flow into water bod...

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, causing serious harm

[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
