Problems solved by technology

[0003] However, compared with chemical pesticides, Beauveria bassiana has disadvantages such as strong hydrophobic effect, single dosage form, and its biological activity is easily affected by the environment, and its work efficiency is low.
During the production and storage process, there are risks such as digestion of spores or inability to fully germinate when used, resulting in low and unstable effects of the product against Beauveria bassiana

Embodiment 1

[0022] Dispersed oil suspension formulation of the present invention, by following mass percentage:

[0023]

[0024] The remainder is rapeseed oil.

[0025] Preparation method: dissolving strigolactone with a small amount of methanol and mixing it into the oil phase carrier, adding surfactants, spore germination promoting substances, and thickeners into the oil phase carrier, grinding the solids to particles with a particle size of 2-3 microns, Add Beauveria bassiana spore powder under stirring, stir well, shear at high speed for 30 minutes, filter to remove residue, and obtain the finished product.

Embodiment 2

[0027] Dispersed oil suspension formulation of the present invention, by following mass percentage:

[0028]

[0029] The remainder is rapeseed oil.

[0030] Preparation method: dissolving strigolactone with a small amount of methanol and mixing it into the oil phase carrier, adding surfactants, spore germination promoting substances, and thickeners into the oil phase carrier, grinding the solids to particles with a particle size of 2-3 microns, Add Beauveria bassiana spore powder under stirring, stir well, shear at high speed for 30 minutes, filter to remove residue, and obtain the finished product.

Abstract

The invention provides a beauveria bassiana dispersible oil suspending agent and an efficient use method thereof. Strigolactones are added into the beauveria bassiana Bb455 dispersible oil suspending agent, and spore germination of the beauveria bassiana can be effectively promoted. A special auxiliary agent for the beauveria bassiana Bb455 can be completely compatible with beauveria bassiana Bb455 spores, has no influence on spore germination, improves the wetting performance and the adhesion performance of the beauveria bassiana Bb455 dispersible oil suspending agent on a target when the beauveria bassiana Bb455 dispersible oil suspending agent is applied, and improves the adhesion rate and the infection rate of the beauveria bassiana Bb455 on target pests, so that the pest killing speed and the prevention and treatment effect are improved.

Description

technical field [0001] The invention relates to the field of biological pesticides and insecticides, in particular to a method for efficiently using Beauveria bassiana strain Bb455. Background technique [0002] Beauveria bassiana is a broad-spectrum entomopathogenic fungus. Because of its strong pathogenicity and environmental friendliness, it has been widely used in the biological control of agricultural, forestry and sanitary pests. The use of Beauveria bassiana to control the masson pine caterpillar and corn borer in my country is the largest pest control project in the world. Achieve good pest control effect continuously. Because Beauveria bassiana has a good control effect on pests and does not cause harm to the environment and human body, it has been paid more and more attention by people. Beauveria bassiana and its preparations are one of the most widely used biological agents. At present, there are 25 pesticide varieties registered in China with Beauveria bassiana...
