Abstract

The invention discloses a cotton bollworm nuclear polyhedrosis virus suspending agent and a preparation method thereof. The composition raw materials are as follows in percentage by weight: 0.42% of 500 billion PIB / g cotton bollworm nuclear polyhedrosis virus parent drug, 10% of methyl oleate, 6% of phenethyl phenol polyoxyethylene ether, 1.5% of an antioxidant BHT, 0.5% of a preservative sodium benzoate, 3% of 12-sodium alkyl sulfate, 2% of sodium lignin sulfonate, 1.5% of white carbon black, 2% of magnesium aluminum silicate, 0.25% of xanthan gum, 0.2% of an organic silicon defoamer and thebalance of deionized water. The cotton bollworm nuclear polyhedrosis virus suspending agent provided by the invention contains 0.42% of 500 billion PIB / g cotton bollworm nuclear polyhedrosis viruses,is high in virion content and low in dosage, has a relatively good effect of preventing and treating cotton bollworms, and is simple in preparation process, low in cost and convenient to popularize and apply.

Description

technical field [0001] The invention relates to the field of novel biological pesticides, in particular to a suspension of cotton bollworm nuclear polyhedrosis virus. Background technique [0002] Cotton bollworm nuclear polyhedrosis virus belongs to the baculoviridae family and consists of double-stranded DNA, protein and trace elements, and the virus particles are single-particle embedded. Cotton bollworm is a major pest that harms the growth of cotton. At present, it is mainly controlled by chemical insecticides. Chemical insecticides are poisonous to humans and animals, harm natural enemies, and pollute the environment. Long-term use of cotton bollworms will produce drug resistance. reduce the control effect. [0003] Bollworm nucleopolyhedrosis virus suspension concentrate is a new type of biological pesticide, which is prepared from nuclear polyhedrosis virus (NVP) and protective agent and other auxiliary materials. Pests infect NVP by eating. Under the action of in...
