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 sterilization composition containing prothioconazole and isoprothiolane and a use thereof. The sterilization composition contains prothioconazole and isoprothiolane as main active components and a weight ratio of prothioconazole to isoprothiolane is 1-70: 1-50. The sterilization composition can be used for preventing and treating cereal, fruit tree and vegetable diseases, has high synergism, can overcome and delay pathogen resistance to drugs, has a fast sterilization speed and a long lasting period, reduces an application cost and has good prevention and treatment effects obviously better than that of a single agent. The sterilization composition can be used for preventing and treating fungal diseases of crops, especially can be used for preventing and treating fungous diseases such as powdery mildew, sheath blight, fusarium wilt, leaf spot, rust, sclerotinia rot, net blotch, leaf scald, botrytis, black spot, brown spot, black shank, rice blast and bacterial leaf blight and has effects 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 rice blastazol 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 C l2 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 p...
