A special synergist for Beauveria bassiana biopesticide and its preparation method and application

Abstract

The invention discloses a special synergist for Beauveria bassiana biological pesticides and a preparation method thereof. The mass ratio of each component is strigolactone 0.05-0.5%, methanol 1-5%, and surfactant 5-5%. 15%, film-forming agent 1-5%, thickener 0.5-5%, glucose 3%, potassium dihydrogen phosphate 0.5%, magnesium sulfate 0.2%, calcium nitrate 0.2%, and the rest is water; Thickener, glucose, potassium dihydrogen phosphate, magnesium sulfate and calcium nitrate are dissolved in water to prepare mixed solution A; strigolactone is dissolved in methanol and introduced into mixed solution A under stirring, and then the surfactant combination is introduced. After stirring, shear at high speed for 30 minutes, remove the residue, and obtain the finished product; the method of use is to prepare the Beauveria bassiana biopesticide into a liquid to be applied according to the instructions, add the product of the present invention, and apply the drug after mixing evenly, which can significantly improve the quality of the ball. Improve the control effect of Beauveria bassiana biopesticides, enhance the quick-acting effect, and prolong the duration of effect.

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...

Problems solved by technology

However, compared with chemical pesticides, there are still many problems in the application of biological pesticides (including Beauveria bassiana biopesticides), such as poor quick-acting products, low control effects, and unstable effects.
