Abstract

The invention discloses a pesticide composition for preventing and treating fungal diseases of plants. The pesticide composition is prepared from the following components in parts by weight: 0.1-1 part of bacillus velezensis HN-2 extract, 45-65 parts of epsilon-polylysine, 10-20 parts of silicon dioxide and 1-5 parts of gamma-aminobutyric acid, wherein the preservation number of the bacillus velezensis HN-2 is CCTCC (China Center For Type Culture Collection) NO: M 2018382. The invention also discloses a preparation method of the pesticide composition. The pesticide composition disclosed by the invention is wide in disease prevention spectrum and has a remarkable prevention and treatment effect on fungal diseases of various plants.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide composition for preventing and treating fungal diseases of plants and a preparation method thereof. Background technique [0002] ε-polylysine (ε-PL) is a polymer of L-lysine. ε-polylysine is a light yellow powder with a slightly bitter taste. It is stable to heat, has strong hygroscopicity, and is insoluble in ether and ethanol. , ethyl acetate and other organic solvents, easily soluble in water. [0003] ε-polylysine (ε-PL) can directly destroy the selectivity of cells and organelles for the survival of substances and the energy metabolism that depends on the integrity of the membrane structure, causing the rupture of the lysosome membrane in the cell, and then inducing the autolysis of microorganisms. effect, leading to cell death. Existing studies have shown that ε-polylysine has a good inhibitory effect on Escherichia coli, Staphylococcus aureus, Lactobacillus bulgari...
