Problems solved by technology

[0006] 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

Embodiment 1

[0043] Example 1: 15% silthiazil · flusilazole wettable powder (1:2)

[0044] Sithiopyram 5g, flusilazole 10g, cleaning agent LS (sodium p-methoxy fatty acid aminobenzene sulfonate) 2g, diffusing agent NNO (sodium methylene bis-naphthalene sulfonate) 4g, white carbon black 5g , kaolin was added to 100g of the mixture for jet milling to prepare a wettable powder with an active ingredient mass percentage of 15% silthiazil·flusilazole.

Embodiment 2

[0045] Example 2: 15% silthiazil · flusilazole wettable powder (1:4)

[0046] Add 3 g of siltianil, 12 g of flusilazole, 3 g of sodium lauryl sulfate, 4 g of diffusing agent NNO, 5 g of white carbon black, and kaolin to 100 g of the mixture and perform jet milling to obtain 15% silthiazin by mass as the active ingredient. Amine·flusilazole wettable powder.

Embodiment 3

Abstract

The invention discloses a sterilization composition containing silthiopham and flusilazole and application thereof. The sterilization composition takes silthiopham and flusilazole as main effective components, wherein the mass ratio of silthiopham to flusilazole is (1-70) to (1-50). The sterilization composition can be applied to prevention and treatment of diseases of cereals, fruit trees and vegetables, has a relatively high synergistic interaction effect and particularly can be applied to prevention and treatment of fungal diseases including take-all disease of wheat, pear scab, wheat glume blotch and the like; the drug resistance of pathogenic bacteria is overcome and delayed, the sterilization speed is high, the lasting period is long and the application cost is reduced; and the prevention and treatment effect is obviously better than that of a single dosage.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with silthiocarb and flusilazole as main active ingredients and its application. Background technique [0002] Silthiopham (Silthiopham), chemical name: N-allyl-4,5-dimethyl-2-(trimethylsilyl)thiophene-3-carboxamide. Sithiopyram has good protective activity, long residual effect period, is relatively safe to crops, mammals and the environment, and has special effects on wheat take-all. [0003] Flusilazole (Flusilazole), molecular formula: C 16 h 15 f 2 N 3 Si, chemical name: bis(4-fluorophenyl)-(1H-1,2,4-triazol-1-ylmethyl)silane. Structural formula: [0004] [0005] Flusilazole is a triazole fungicide, the mechanism of action is to destroy and prevent the biosynthesis of ergosterol, resulting in the failure of cell membrane formation and the death of germs. It is effective against diseases caused by Ascomycetes, Basidiomyce...
