Abstract

The invention discloses a bactericidal composition formed by compounding benzothiostrobin and kasugamycin. The weight ratio of the benzothiostrobin to the kasugamycin in the composition is 1:30 to 30:1. By an indoor toxicity test and a field efficacy test, the bactericidal composition disclosed by the invention has obvious synergism for preventing and controlling cucumber downy mildew, can achieve the aims of using lower dose and improving the preventing and controlling effect, and is worthy of being popularized and applied to production.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and in particular relates to a bactericidal composition of penthiostrobin and kasugamycin and an application thereof. Background technique [0002] Kasugamycin is a low-toxicity, systemic fungicide. It is a special antibiotic for the prevention and treatment of rice blast. In addition, it has a good control effect on various pathogenic fungi such as cucumber downy mildew, anthracnose, bacterial angular spot, tomato gray mold and so on. [0003] Benthiastrobin is a new type of methoxyacrylate fungicide developed by Central China Normal University. It has the advantages of broad bactericidal spectrum, high bactericidal activity, low application amount, and long-lasting effect. It has both therapeutic and protective effects. Not only has good control effect on cucumber downy mildew and powdery mildew, but also has excellent control effect on scab, anthracnose, gray mold, corn leaf spot, rice s...
