Biological pesticide mixed with plant insecticide sterilization component and amino-oligosaccharin and preparation method thereof

Abstract

The invention relates to an ecological agricultural drug and a preparing method compounded by a content of Chinese traditional herb plant insecticide and amino group oligosaccharide. The ecological agricultural drug is refined by blending and processing the plant gradients containing one or a plurality of insecticide and disinfecting components and the Chitosante raw materials and solutions which are extracted with the amino group oligosaccharide. The weight percentages of all components are respectively: five to thirty percent of plant materials, seventy to ninety five percent of Chitosante material, and the solvents are alcohol and water. When in blending and configuring process, additives are added; wherein, the additives are one or a plurality of the agents, such as an antiseptic agent, a dispersing agent, a surface active agent, a penetrant or an emulsifying agent. The plant materials are materials such as Sophora flavescens, tobacco, Indian chinaberry fruit, pyrethrum, climbing groundsel or Aztec marigold, etc., the invention has the beneficial effects of multifunction of insecticide and disinfection, anti disease, disease prevention; easy degradation of the product, no residues and extensive raw material source. The working process of the invention simplifies the processes of extraction, condensation and filter with low producing cost.

Description

Technical field [0001] The invention belongs to the field of biomedicine and relates to an ecological pesticide composed of plant insecticidal and bactericidal ingredients and amino oligosaccharides and a new method of its preparation process. Background technique [0002] Rice stripe leaf blight is a common disease that uses rice planthoppers as hosts and is widely infected and spread through it. It often occurs in major rice-producing areas in Southeast Asia. The disease spreads rapidly and is highly destructive, often causing widespread infection of crops, resulting in reduced yields or even no harvests. At present, my country's domestic chemical and biological pesticide products can reduce and alleviate this type of disease to a certain extent. However, since striped leaf blight virus is spread by rice planthoppers, which are extremely resistant to pesticides and have extremely high reproductive capacity, the compound infection spreads concurrently, which brings great c...

AI Technical Summary

Problems solved by technology

However, because the stripe leaf blight virus is transmitted by rice planthoppers, and rice planthoppers are a kind of vicious insect pests with strong resistance to pesticides and high reproductive ability, such compound infections are transmitted concurrently at the same time. The prevention and cure of the disease brings great difficulties

In addition, in the existing pesticide products, insecticides only kill insects, and bacteriostats only inhibit bacteria. To eradicate the disease through conventional legal methods, at least the medicines should be sprayed separately for insect pests and diseases separately, and according to the application cycle repeats several times

It takes several cycles to get the effect, and in the process of doing so, it will inevitably cause a lot of waste of various resources such as pesticides, labor, water and energy.
