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 discloses a bactericidal composition containing thifluzamide and fludioxonil and an application thereof. The bactericidal composition takes thifluzamide and fludioxonil as main active ingredients, wherein the weight ratio of thifluzamide to fludioxonil is (1-70):(1-50). The bactericidal composition can be used for preventing the diseases of cereal, melon and fruit or vegetable crops, has relatively high synergistic effect, overcomes and delays the drug resistance of germs, and realizes high bactericidal speed and long duration while the application cost is reduced and the prevention effect is obviously better than that of using a single agent. The bactericidal composition disclosed by the invention can be used for preventing fungal diseases of crops and particularly can be used for preventing the fungal diseases such as leaf blight, rust disease, powdery mildew, downy mildew, epidemic disease, anthracnose, scab, brown spot, damping off, gray mold and the like, and the effect is better than that of using a single agent.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with thifuramide and fludioxonil as main active ingredients 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, chemical structural formula [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 content, it has strong competitiveness i...
