Problems solved by technology

However, many studies have shown that if these two agents are used alone to prevent and control diseases, they can make pathogenic bacteria resistant to them in a short period of time, resulting in reduced control effects and even failure of control.

Abstract

The invention discloses a bactericidal composition comprising probenazole and thifluzamide. The active ingredients of the bactericidal composition are probenazole and thifluzamide in a weight ratio of 1: 20 to 20: 1, and the active ingredients in the composition account for 5-60% by mass. The bactericidal composition disclosed by the invention is high in bactericidal activity, delays generation and development of drug resistance of pathogens, reduces the preventing and treating dosage in the actual production, and is economical, efficient, safe and environmental-friendly. The bactericidal composition disclosed by the invention has a good preventing and treating effect on various crop diseases, and particularly has a remarkable preventing and treating effect on rice sheath blight disease.

Description

technical field [0001] The invention relates to the field of agricultural fungicides, in particular to a fungicidal composition containing thiabendazole and thiafluxamide and an application thereof. Background technique [0002] Rice sheath blight is a worldwide epidemic disease caused by Rhizoctonia solani, and it is also one of the most important diseases of rice in my country. Its distribution is very wide, and it occurs in all major rice producing areas in my country, especially in the middle and lower reaches of the Yangtze River and South China. The damage is very serious, resulting in a sharp decline in yield. Breeding and promoting disease-resistant varieties is one of the important measures to prevent and control rice sheath blight. In recent years, although scholars at home and abroad have made a lot of progress in disease-resistant breeding, there is still no one that is completely resistant to rice sheath blight. Immunized rice varieties. At present, the contro...
