Problems solved by technology

However, this patent does not take into account the effect of the suspending agent entering the plant tissue; the pesticide components in the suspending agent exist in the form of tiny particles, and the speed of entering the plant tissue is slow, and it takes a long period of time to exert its medicinal properties. effect, and the pesticide ingredients will also deteriorate due to the external environment during this period of time.

Abstract

The invention belongs to the technical field of pesticide production, in particular to a Macleaya cordata water suspension agent biological pesticide and a preparation method thereof. The biological pesticide comprises the following components in percentage by weight: 99.7%-99.8% of component a, 0.20-0.30% of component b; the component a comprises the following components in percentage by weight: 1%-5% of Macleaya cordata alkaloids, 5%-20% of dispersant, 0.5%-5% of thickener, 1%-15% of antifreezing agent, 0.5%-10% of stabilizer and that balance of deionize water; the component b is a mixture of penicillium, azotobacter and bacillus subtilis. The Macleaya cordata water suspension agent biological pesticide provided by the invention is safe for operators and users because no or less organic solvents are used and no dust is generated. The Macleaya cordata water suspension agent biological pesticide can be uniformly mixed and dispersed with water in any proportion, less effected by the quality of water and easy to use and not easy to pollute the environment. It is an environmentally compatible water-based pesticide dosage form and has fast action and strong effect and has a good market prospect.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, in particular to a biopesticide of Boluo backwater suspension and a preparation method thereof. Background technique [0002] Boluohui, belonging to the genus Boluohui of the poppy family, is a pure natural green biological "three medicines" product. The alkaloids contained in Boluohui, such as sanguinarine, chelerythrine, Boluohuijing, etc., have good insecticidal and bacteriostatic effects; they can be used to prevent and control diseases and insect pests of fruits, vegetables, food crops, cotton, etc. biopesticide raw materials. Moreover, the active ingredients of Boluohui botanical pesticides are easy to degrade, and it is one of the most ideal varieties of existing biological pesticides. It is highly efficient, non-toxic, non-polluting, and has the effect of improving soil. [0003] At present, the agents of Boluohui biological pesticides are mainly water-dispersible granules,...
