Insect baculovirus pesticides in dosage form of water dispersible granule and preparation

Abstract

The invention relates to a water dispersion granula preparation formulation of an insect baculovirus pesticide and a preparation thereof, which is a solid water dispersion granula preparation formulation and comprises 10-500 billion PIB / g of the insect baculovirus raw powder and accessory agents, the accessory agents comprise vector, dispersant, wetting agent, disintegrant, light protective agent and bond. The proportion of weight portion of every component is as follows: 1 to 50 portions of the insect baculovirus raw powder, 1 to 70 portions of the vector, 1 to 20 portions of the dispersant, 0 to 20 portions of the wetting agent, 1 to 20 portions of the disintegrant, 0.5 to 20 portions of the light protective agent and 1 to 20 portions of the bond. The preparation method is that the insect baculovirus raw powder and the accessory agents are mixed by certain proportion to be crushed by airflow for granulating and drying to obtain the water dispersion granula preparation formulation of the insect baculovirus pesticide which can be used separately and also can be used by combing with chemical pesticide. The water dispersion granula preparation formulation of the insect baculovirus pesticide has the advantages of little pollution caused by producing and processing process, long shelf life, stable product quality, good dispersibility, easy storage, convenient transportation, extremely low dosage and high virus content, which has significant meaning for preventing and curing insects in agriculture and forestry.

Description

technical field

[0001] The invention relates to an insect baculovirus insecticide and a preparation method thereof, in particular to an ultra-low dosage and high content water-dispersible granule type insect baculovirus insecticide and a preparation method. Background technique

[0002] The main hosts of Baculoviridae viruses are insects, which can cause the host insects to suffer from baculovirus diseases and die, and can be made into insecticides to control agricultural and forestry pests. Insect baculovirus insecticides (referred to as virus insecticides) are a class of pure natural, green and environmentally friendly biological pesticides. At present, the amount of chemical pesticides used per unit area is getting higher and higher, and the harm to the environment, non-target animals, biodiversity and humans is becoming more and more serious. A large number of highly toxic and high-residue pesticides are restricted in production, Prohibition, restriction and prohibition...
