Abstract

The invention discloses a virus insecticide suspension agent containing chitosan. The virus insecticide suspension agent comprises virus raw powder and chitosan, wherein the concentration of the chitosan in the virus insecticide suspension agent is 30-120mg / L; the concentration of the virus raw powder in the virus insecticide suspension agent is 1-300 hundred million PIB / ml; the content of a stabilizer in the virus insecticide suspension agent is 2-5wt%; the content of a surfactant in the virus insecticide suspension agent is 5-10wt%; the content of a synergist in the virus insecticide suspension agent is 0.1-0.5wt%; the content of an optical protection agent in the virus insecticide suspension agent is 0.01-0.1wt%; the content of a dispersing agent in the virus insecticide suspension agent is 1-2wt%; the balance is sterile water. The chitosan can induce a plant to generate chitinase, damage peritrophic membrane of insects and promote the infection of insect virus so as to guarantee the insect-killing speed; the chitosan has a certain optical protection function to insect virus, so that the virus in the field is more stable; the compound of the chitosan and the virus insecticide suspension agent in the invention can obviously promote the insect-killing capacity of the insecticide.

Description

technical field [0001] The invention belongs to the technical field of biological insecticides, and in particular relates to a chitin-containing virus insecticidal suspension and a preparation method thereof. Background technique [0002] my country is a large agricultural country with many types of crops. It is also a country with frequent and frequent occurrence of biological disasters such as diseases and insect pests. There are many types, serious degrees, high frequency and wide areas of disease and insect pests, which pose a great threat to the growth of my country's crops. At present, the prevention of agricultural and forestry pests in our country mainly relies on chemical pesticides. The long-term and single use of chemical pesticides has caused pests to develop resistance. In order to achieve the effect of pest control, the toxicity and usage of chemical pesticides have to be increased. This will not only affect food safety and The ecological environment has caused...
