Sterilization composition and application thereof

Abstract

The invention relates to the field of pesticide preparations, and discloses a sterilization composition and application thereof. The sterilization composition disclosed by the invention comprises an alternaria tenuissima activator protein and an active ingredient A, wherein the weight ratio of the alternaria tenuissima activator protein to the active ingredient A is (1:50)-(30:1), the active ingredient A is selected from amide fungicides, strobilurin fungicides, pyrrole fungicides, triazole fungicides, pyrimidine fungicides, pyridine fungicides or carbamate fungicides, and one or more than two fungicides is selected from each type of fungicides. According to the sterilization composition, the amide fungicides, the strobilurin fungicides, the pyrrole fungicides, the triazole fungicides, the pyrimidine fungicides, the pyridine fungicides or the carbamate fungicides and the alternaria tenuissima activator protein are compounded, and have complementary advantages, thus the resistance of vegetables on diseases can be improved through once application of the sterilization composition, the yield of vegetable crops can be increased, and the amount and frequency of applying the pesticide are reduced.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a bactericidal composition and its application. Background technique [0002] Alternaria ultrafines activating protein is a biologically active, single, stable protein that is fermented and extracted from Alternaria ultrafinesii. The protein consists of 207 amino acids. When it comes into contact with the surface of plant organs, it can bind to the receptor protein on the plant cell membrane, causing an increase in the activity of a series of related enzymes and gene expression in the plant, stimulating a series of metabolic regulation in the plant, and promoting the growth of plant roots, stems and leaves. Increase chlorophyll content and increase crop yield. [0003] Amide fungicides are effective against wheat rust pathogens of the genus Monocystis, Puccinia, and black rust pathogens of smut, Tilletia, and root rot on tomato, eggplant, cucumber and other crops. Soil fun...

Problems solved by technology

[0010] However, the single use of these pesticides for a long time is not only not ideal for the efficacy, but also not conducive to the improvement of crop yield, and it is easy to produce drug resistance
