Sterilization composition containing prothioconazole and prochloraz-manganese chloride and application thereof

Abstract

Disclosed in the present invention is a fungicidal composition containing prothioconazole and a prochloraz manganese salt and use thereof. The fungicidal composition uses prothioconazole and a prochloraz manganese salt as the main active ingredients. The fungicidal composition may be applied to control cereal, fruit, and vegetable diseases, and has high synergistic effects, overcomes and delays the resistance of pathogenic fungi, and has a fast fungicidal speed and long duration. The application cost is reduced, and the control effect is significantly better than that of a single agent. The present invention may be used to control fungal diseases on crops, and in particular, can be used to control powdery mildew, sheath blight, fusarium wilt, leaf spot, rust disease, stalk break, net blotch, scald disease, gray mold, black spot, brown blotch, black shank, cucumber, citrus and pimento anthracnose, citrus stem-end rot, green mold, penicilliosis and mushroom brown rot, and the effects are better than that of a single agent.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with prothioconazole and prochloraz manganese salt 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 ...

AI Technical Summary

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
