Problems solved by technology

[0010] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of ​​economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge

Abstract

The invention belongs to the field of pesticides, and discloses a bactericidal composition containing thifluzamide and epoxiconazole and application thereof. The bactericidal composition uses thifluzamide and epoxiconazole as main effective components, wherein the weight ratio of the thifluzamide to the epoxiconazole is (1-70):(1-50). The bactericidal composition can be used for preventing and treating diseases on cereals, melons and fruits, or vegetable crops, has higher synergic effect, overcomes and postpones the drug resistance of pathogenic bacteria, has the advantages of high bactericidal speed and long duration time, lowers the use cost, and has obviously better preventing and treating effects than a single agent.

Description

Technical field: [0001] The invention belongs to the field of pesticides and relates to a bactericidal composition and its application, in particular to a bactericidal composition containing thifuramide and epoxiconazole and its application. Background technique [0002] Thiofuramide (Trifluzamide), also known as Thiofluramide, chemical name: 2',6'-dibromo-2-methyl-4'-trifluoromethoxy-4-trifluoromethyl-1,3- Thiadiazole-5-hydroxyanilide, molecular formula C 13 h 6 Br 2 f 6 N 2 o 2 S, the chemical structural formula is as follows: [0003] [0004] Thiofuramide has low toxicity: acute oral LD50 of rats>5000mg / kg, acute percutaneous LD50 of rats>5000mg / kg, acute inhalation of LC50 of rats>50001.4mg / L air. Moderately irritating to rabbit eyes and slightly irritating to rabbit skin. Belonging to the thiazole amide fungicides, it has strong systemic conductivity and long-lasting effect. Thiofuramide is a succinate dehydrogenase inhibitor. Due to its fluorine c...
