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 suspending agent formulation of the present invention, by following mass percentage:

[0023]

[0024] The remaining components are rapeseed oil.

[0025] Preparation method: Dissolve strigolactone with a small amount of methanol and mix it into the oil phase carrier, add surfactant, spore germination promoting substance and thickener to the oil phase carrier, grind the solid to particles with a particle size of 2-3 microns, Beauveria bassiana spore powder was added under stirring, fully stirred and then sheared at high speed for 30 minutes, and the residue was removed by filtration to obtain a finished product.

Embodiment 2

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

[0028]

[0029] The remaining components are rapeseed oil.

[0030] Preparation method: Dissolve strigolactone with a small amount of methanol and mix it into the oil phase carrier, add surfactant, spore germination promoting substance and thickener to the oil phase carrier, grind the solid to particles with a particle size of 2-3 microns, Beauveria bassiana spore powder was added under stirring, fully stirred and then sheared at high speed for 30 minutes, and the residue was removed by filtration to obtain a finished product.

Embodiment 3

[0032] Dispersed oil suspending agent formulation of the present invention, by following mass percentage:

[0033]

Abstract

The invention provides a Beauveria bassiana dispersible oil suspension agent and an efficient use method. The Beauveria bassiana Bb455 dispersible oil suspension agent is added with strigolactone, which can effectively promote the spore germination of Beauveria bassiana. A special additive for Beauveria bassiana Bb455, which is completely compatible with Beauveria bassiana Bb455 spores, has no effect on spore germination, and improves the wetting performance of Beauveria bassiana Bb455 dispersible oil suspension on the target when applied. It can improve the adhesion rate and infection rate of Beauveria bassiana spores Bb455 on target pests, thereby improving the insecticidal speed and control effect.

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 in my country to control masson pine caterpillars and corn borers is the largest pest control project in the world. Obtain 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 preparations. At present, there are 25 pesticide varieties registered in China with Beauveria bassi...
