Abstract

The invention relates to the technical field of agricultural bactericide, and particularly relates to a bactericide composition which contains Zhongshengmycin and bromothalonil according to a weight ratio of 1:(5-40). The bactericide composition is used for preventing and controlling bacterial and fungal diseases of plant. The bactericide composition realizes an obvious synergistic effect and high control efficiency in field, and has wide bactericidal spectrum and a perfect effect in preventing and controlling many bacterial and fungal diseases of plant; the prevention and control cost is low, the drug use cost is lowered, and the labor force of farmers is saved; and the technical threshold is low, and the production technology is simple.

Description

technical field [0001] The invention relates to the technical field of agricultural fungicides, in particular to a fungicide composition, and also relates to the application of the fungicide composition. Background technique [0002] In agricultural production practice, plant bacterial diseases and fungal diseases often occur together. In order to reduce the harm of germs, a large number of fungicides are often used. Some fungicides have to increase the dosage because the bacteria have developed resistance to them, which makes the control effect decline. Some fungicides have a narrow control spectrum, and farmers must use multiple fungicides together. The abuse of chemical fungicides has caused serious environmental pollution and food safety problems. The development of new fungicides is an important way to solve the above dilemma. [0003] Zhongshengmycin (zhongshengmycin) belongs to N-glycosides and is a broad-spectrum agricultural bactericidal antibiotic. It inhibits ...
