Embodiment 1

[0031] Each component is proportioned according to the following mass percentages:

[0032] Bacillus thuringiensis: 2%; Ethanol: 8%; Castor oil: 8%; Calcium lignosulfonate: 7%; Calcium carbonate: 0.4%; Urea: 9%; the rest is water.

[0033] Put Bacillus thuringiensis in a reactor, dissolve it with ethanol, then add castor oil, mix well to obtain an oil phase mixture; put water in another reactor, add calcium lignosulfonate, calcium carbonate, urea and mix well, The water phase mixture is obtained; the oil phase mixture and the water phase mixture are evenly mixed and stirred for about 30 minutes to prepare the biopesticide.

Embodiment 2

[0035] Each component is proportioned according to the following mass percentages:

[0036] Bacillus thuringiensis: 1.8%; Ethanol: 6%; Castor oil: 7%; Calcium lignosulfonate: 6%; Calcium carbonate: 1%; Urea: 5%; the rest is water.

[0037] Put Bacillus thuringiensis in a reactor, dissolve it with ethanol, then add castor oil, mix well to obtain an oil phase mixture; put water in another reactor, add calcium lignosulfonate, calcium carbonate, urea and mix well, Obtain the water phase mixture; mix the oil phase mixture and the water phase mixture evenly, and stir for about 0.5 hours to prepare the biopesticide.

Embodiment 3

[0039] Each component is proportioned according to the following mass percentages:

[0040] Bacillus thuringiensis: 2.5%; Ethanol: 7%; Castor oil: 9%; Calcium lignosulfonate: 8%; Calcium carbonate: 0.7%; Urea: 10%; the rest is water.

[0041] Put Bacillus thuringiensis in a reactor, dissolve it with ethanol, then add castor oil, mix well to obtain an oil phase mixture; put water in another reactor, add calcium lignosulfonate, calcium carbonate, urea and mix well, Obtain the water phase mixture; mix the oil phase mixture and the water phase mixture evenly, and stir for about 0.5 hours to prepare the biopesticide.

Abstract

The invention relates to a biological insecticide. The biological insecticide is characterized by consisting of the following components in percentage by mass: 1.8-2.5 percent of bacillus thuringiensis, 6-8 percent of a solvent, 7-10 percent of an emulsifier, 5-10 percent of a dispersant, 0.4-1 percent of a thickening agent, 3-11 percent of an antifreeze agent and the balance being water. The biological insecticide disclosed by the invention has lower toxicity than an existing biological insecticide.

Description

technical field [0001] The invention relates to the field of biopesticides, in particular to a biopesticide containing Bacillus thuringiensis and a preparation method thereof. Background technique [0002] As we all know, insecticides and fungicides can prevent and control plant diseases and insect pests. In recent years, due to the extensive use of organic synthetic chemical pesticides, a series of well-known problems such as environmental pollution, ecological balance destruction and food safety have been brought about, which have caused many adverse effects on promoting the sustainable development of agricultural economy. [0003] Biological pesticides have the advantages of low toxicity, strong selectivity, and less resistance to drug resistance. They have been widely used in some fields, such as agricultural antibiotics, botanical pesticides, and viral pesticides. However, the current biopesticides still have certain toxicity and pose a threat to food safety. How to ma...
