Abstract

The invention discloses a special synergist for beauveria bassiana biopesticide and a preparation method thereof, the special synergist is prepared from the following components in percentage by mass:0.05-0.5% parts of strigolactones, 1-5% parts of methanol, 5-15% parts of surfactant, 1-5% parts of filmogen, 0.5-5% parts of thickener, 3% parts of glucose, 0.5% parts of monopotassium phosphate, 0.2% parts of magnesium sulfate, 0.2% parts of calcium nitrate, and the balance of water. dissolving the filmogen, the thickener, glucose, monopotassium phosphate, magnesium sulfate and calcium nitratein water to prepare mixed liquor A; dissolving strigolactones in methanol and introducing the mixed liquid A at a stirring state, then adding a surfactant combination, after stirring, carrying out high-speed shearing for 30 min, then removing residue to obtain a finished product, the application method is to prepare the beauveria bassiana biopesticide into liquid pesticide to be applied accordingto the specification, then adding the product provided by the invention, applying the special synergist after mixing uniformly, the special synergist can significantly improve the prevention and control effect of the beauveria bassiana biopesticide, enhance the fast-acting property is enhanced and the period of preserving effect is extended.

Description

technical field [0001] The invention relates to the field of pesticides and insecticides, in particular to a special synergist for Beauveria bassiana biological pesticides and a preparation method thereof. Background technique [0002] Since the 1990s, with the increasing requirements of human beings on the environment and the quality and safety of agricultural products, pesticides must be developed in the direction of low toxicity and pollution-free, and biopesticides are a kind of products that meet the above requirements and are compatible with the environment. Green pesticides. Biological pesticides use living organisms (fungi, bacteria, viruses, genetically modified organisms, natural enemies, etc.) or their metabolites to kill or inhibit agricultural harmful organisms. They are also called natural pesticides. Compared with chemical pesticides, they have strong selectivity and no pollution. , It is not easy to produce drug resistance, does not destroy the ecological en...
