preparation example Construction

[0020] A preparation method of high-efficiency biological insecticide, comprising the steps of:

[0021] (1) Take deionized water and place it in a magnetic field generator, and pretreat it at a current intensity of 0.2A and a magnetic field intensity of 14.4Gs for 1~2h to obtain pretreated deionized water. Take 5~8 parts of beef extract by mass , 20~30 parts of bacteria chaff, 2~4 parts of soybean cake powder, 10~13 parts of peptone, 3~5 parts of glucose, 2~4 parts of sodium chloride, 0.3~0.5 parts of iron sulfate, 0.3~0.6 parts of magnesium sulfate, 0.3~0.5 parts of potassium dihydrogen phosphate, 0.03~0.06 parts of manganese sulfate, 1000 parts of pretreated deionized water, pH 7.5, sterilized at 121°C for 20 minutes to obtain the sterilized product;

[0022] (2) Mix Bacillus thuringiensis, Ascospora, and Molleri in a mass ratio of 3~5:1~3:1~3 to obtain a mixed bacterial agent, and take the mixed bacterial agent to inoculate at an inoculation amount of 4~6%. Put it into th...

Abstract

The invention discloses a preparation method of an efficient biological insecticide, and belongs to the technical field of pesticide preparation. The method includes the steps: performing magnetization pretreatment on deionized water to stimulate the spore production performance of bacillus thuringiensis, aschersonia and Moller bacteria; wrapping food and digestive enzyme to enter an intestinal tract to be digested and absorbed; destroying and penetrating an intestinal membrane to prevent insects from normally molting and transfiguring to kill the insects. Methyl polyethylene glycol and succinic anhydride serves as raw materials, enzyme production active centers are protected, insect killing performance is improved, L-canavanine, cinnamic acid and P-cumaric acid are added, penetration of insect killing active components is facilitated, nutrient substances for inducing injurious insects are added, the grazing rate of the injurious insects for the insecticide is increased, Congo red is added, ultraviolet light is absorbed, active bacterium agents are protected, and contact killing effect is enhanced. The efficient biological insecticide solves the problems that a current insecticideis poor in insect killing efficiency and short in insect killing effective time, and the injurious insects can generate drug resistance when the current insecticide is used.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparation, and in particular relates to a preparation method of a high-efficiency biological insecticide. Background technique [0002] With the promotion of urban landscaping, more and more mosquitoes will be hidden in the grass of the landscaping, which will bring harm to passers-by or garden leisurers. However, most of the existing methods for eliminating mosquitoes are spraying chemicals. , the medicament continues to volatilize, and the efficacy of the drug decreases accordingly, and it can only have a short-term effect of mosquito repellent and insect repellent. The afforestation of landscaping that causes the benefit of mankind has become the health threat of people. The current pest control not only has poor control effect, but also uses different insecticides for different pests, which consumes a lot of manpower, material resources and financial resources, and also causes environment...
