Abstract

The invention discloses an insecticidal composition containing beauveria bassiana and a preparation method thereof. The insecticidal composition containing the beauveria bassiana comprises the following raw material components in percentage by mass: 10 to 50 percent of beauveria bassiana spore powder (with the content of 100 billion pores / gram), 0.01 to 5 percent of a beauveria bassiana spore germination promoting substance, 5 to 30 percent of a surfactant, 0.1 to 10 percent of a thickening agent and the balance of an oil-phase carrier. The composition disclosed by the invention is applied toprevention and control of crop insects including cnaphlocrocis medinais, ostrinia nubilalis and the like; and the composition has the advantages of good quick-acting effect, stable prevention and control effect, environment friendliness and the like.

Description

technical field [0001] The invention relates to the field of biological pesticides and insecticides, in particular to a biological insecticidal composition containing Beauveria bassiana and a preparation method thereof. Background technique [0002] Beauveria bassiana (Bals.) Vuillemin is a broad-spectrum entomopathogenic fungus with strong pathogenicity and a wide range of insecticides. It is widely used in Dendrolimus punctatus Walker and Ostrinia furnacalis in China. Prevention and control of various agricultural and forestry pests such as Guenée. At present, there are 22 varieties of pesticides registered in China with Beauveria bassiana as the active ingredient, including 16 preparations. However, compared with chemical pesticides, the active ingredient of Beauveria bassiana biopesticides is the spores of Beauveria bassiana, and there are risk factors in the production and storage of the product that lead to the death of the spores or the germination of the product bef...
