Abstract

The invention discloses a bactericidal composition containing pyrimethanil and nikkomycin and a preparation thereof, and relates to the technical field of pesticides. The bactericidal composition contains active components pyrimethanil and nikkomycin, and the mass ratio of pyrimethanil to nikkomycin is 1:40-10:1. Compared with a single agent, the composition of the present invention has obvious synergistic effect, and can effectively control diseases of cereals, various fruit trees, and vegetable crops, such as wheat powdery mildew, rice blast, apple ring spot, tomato leaf mold, Strawberry powdery mildew, cucumber gray mold, etc., reduce the dosage of pesticides, save the cost of pesticides, and at the same time make up for the shortage of single doses and the tolerance of pests to them, and improve the insecticidal activity.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a bactericidal composition mixed with two insecticidal active compounds, in particular to a bactericidal composition containing pyrimethanil and nikkomycin and a preparation thereof. Background technique [0002] In pesticide research, compounding ingredients from different varieties is a very common way to control resistant pests or bacteria. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compound is synergistic, additive or antagonistic. The formula with good compounding and synergistic effects can significantly improve the actual control effect and reduce the use of pesticides, thereby greatly delaying the generation of pest resistance, and is an important means of comprehensive pest control. [0003] Nicomycin is a metabolite produced by Streptomyces chromogenes 7100 isolated from Northeast soil by the ...
