Problems solved by technology

However, syringstrobin is a methoxyacrylate compound, and its mechanism of action is single. Long-term repeated use in the field may lead to selectivity of fungal strains in many cases. The control effect of esters on these fungi is reduced or even ineffective, resulting in the expansion and spread of diseases, crop yield reduction, and waste of pesticides

Abstract

The invention discloses a bactericidal composition containing N,N-diethylphenazine-1-carboxamide and coumoxystrobin and application thereof; the bactericidal composition comprises the active ingredients, N,N-diethylphenazine-1-carboxamide and coumoxystrobin, wherein the weight ratio of the N,N-diethylphenazine-1-carboxamide to coumoxystrobin is 1:20 to 20:1; the bactericidal composition has synergy within the above ratio range and is effective in preventing and treating rice sheath blight disease.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and in particular relates to a fungicidal composition containing phenethromycin and syringstrobin and its application. Background technique [0002] Rice sheath blight, also known as moire, is commonly known as flower foot stalk, rotten foot blast, eyebrow spot. It is caused by infection by Rhizoctonia solani, and it mostly occurs under high temperature and high humidity conditions. Sheath blight is one of the major diseases in rice production, which is a serious hazard in southern rice areas. The disease prevents the rice from heading, or there are more grains in the heading, and the grain weight decreases. The application of chemical agents is the most effective means to prevent and control plant fungal diseases, but the long-term continuous application of a single chemical fungicide in high doses is likely to cause problems such as drug residues, environmental pollution, and the develop...
