A kind of bactericidal composition containing thifuramide and triadol and its application

Abstract

The invention belongs to the field of pesticides, and discloses a bactericidal composition containing thifluzamide and flutriafol and application thereof. The bactericidal composition uses thifluzamide and flutriafol as main effective components, wherein the weight ratio of the thifluzamide to the flutriafol is (1-70):(1-50). The bactericidal composition can be used for preventing and treating diseases on cereals, fruit trees and 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 triadol and its application. Background technique [0002] Thifluzamide, chemical name: 2',6'-dibromo-2-methyl-4'-trifluoromethoxy-4-trifluoromethyl-1,3-thiadiazole-5- Hydroxyanilide, the structural formula is as follows: [0003] [0004] Thiofuramide is currently a micro-toxic fungicide developed by Dow AgroSciences, an acute oral LD ​​in rats 50 >5000mg / kg, acute percutaneous LD in rats 50 >5000mg / kg, rat acute inhalation LC 50 >50001.4mg / L. The drug is a thiazole amide fungicide, and its mechanism of action is a succinate dehydrogenase inhibitor, that is, it inhibits the synthesis of succinate dehydrogenase in the fungal tricarboxylic acid cycle. It also has strong systemic conductivity and can be used For rice, other cereal crops, lawns, peanuts, po...

AI Technical Summary

Problems solved by technology

Under the recommended dose, it is safe for crops and has no harmful phenomena, but when used alone, the problem of resistance must be paid attention to

[0008] In recent years, rice sheath blight, rice blast, rice smut, wheat sheath blight, moire, leaf spot, net spot, smut, tickle smut, powdery mildew, rust, and downy mildew have occurred Serious, often causing catastrophic losses. Although thifuramide and triadol have relatively ideal control effects, in practical applications, the 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 disease occurrences have increased, making it more difficult to control; The control effect of pesticides is greatly reduced, and plant disease control is facing major challenges
