Problems solved by technology

[0008] 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 prothioconazole and tebuconazole and application thereof. The bactericidal composition uses prothioconazole and tebuconazole as the main effective components. The insecticidal composition can be applied to control of diseases of cereal, fruit trees and vegetables, has high synergetic effects and overcomes and delays pathogen resistance; and the bactericidal composition has the advantages of high insecticidal speed, long effective period, reduced application cost and control effect obvious better than that of single dose usage. The insecticidal composition can be used for control of fungal diseases on crops, in particular for control of powdery mildew, sheath blight, wilt, leaf spot, rust, stalk break, net blotch, scald, botrytis, black spot, brown blotch, black shank and smut, and has better effect than single dose usage.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with prothioconazole and tebuconazole as main active ingredients and its application. Background technique: [0002] Prothioconazole is a new broad-spectrum triazolethione fungicide developed by Bayer, chemical name: 2-(2-(1-chlorocyclopropyl)-3-(2-chlorophenyl )-2-hydroxypropyl-1-2-dihydro-3-1,2,4-triazole-3-thio, molecular formula: C 14 h 15 Cl 2 N 3 OS. The structural formula is as follows: [0003] [0004] The mechanism of action of prothioconazole is to inhibit the demethylation at the l4 position of the precursor of sterol in fungi - lanosterol or 24-methylene dihydromimaudine, namely demethylation inhibitors (DMIs) . Not only has good systemic activity, excellent protection, treatment and eradication activity, but also has a long lasting effect. Through a large number of field efficacy tests, the results show that pro...
