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 components and amino oligosaccharins and a new preparation method thereof. Background technique [0002] Rice stripe leaf blight is a common disease that is widely infected and spread by the rice pest - rice planthopper as the host, and it often occurs in the main rice producing areas of Southeast Asia. The disease spreads rapidly and has strong destructive power, often causing large-scale infection of crops, resulting in reduced production or even no harvest. At present, my country's domestic chemical and biological pesticide products can alleviate and relieve such diseases to a certain extent. 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 inf...

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 b
