Problems solved by technology

[0007] 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

[0044] Example 1: 15% pyraclostrobin · carbendazim wettable powder (1:2)

[0045] Put 5 g of pyraclostrobin, 10 g of carbendazim, 2 g of cleaning agent LS (sodium p-methoxy fatty acid aminobenzene sulfonate), 4 g of diffusing agent NNO (sodium methylene bis-naphthalene sulfonate), white carbon black 5 g of kaolin was added to 100 g of the mixture for jet milling to prepare a wettable powder with an active ingredient mass percentage of 15% pyraclostrobin·carbendazim.

Embodiment 2

[0046] Example 2: 15% pyraclostrobin · carbendazim wettable powder (1:4)

[0047] Add 3 g of pyraclostrobin, 12 g of carbendazim, 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 for jet milling to obtain 15% mass percent of pyrazole Naproxil · Carbendazim wettable powder.

Embodiment 3

[0048]Example 3: 14% pyraclostrobin · carbendazim wettable powder (1:6)

[0049] Add 2 g of pyraclostrobin, 12 g of carbendazim, 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 14% mass percent of pyrazole Naproxil · Carbendazim wettable powder.

Abstract

The invention discloses a sterilization composition containing isopyrazam and carbendazim and application of the sterilization composition. The sterilization composition comprises isopyrazam and carbendazim as main effective components, wherein the mass ratio of isopyrazam to carbendazim is (1-70):(1-50). The sterilization composition can be used for preventing and treating diseases of cereals, fruit trees and vegetables, has a relatively good synergistic effect, overcomes and retards drug resistance of bacteria and is high in sterilization speed and long in lasting period, the application cost is lowered, and the prevention and treatment effect of the sterilization composition is remarkably superior to that of a single reagent. The sterilization composition can be used for preventing and treating fungous diseases of crops, particularly fungous diseases such as rice sheath blight diseases, rice blast and pepper phytophthora blight, and the effect of the sterilization composition is remarkably superior to that of the single reagent.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with pyraclostrobin and carbendazim as main active ingredients and its application. Background technique [0002] Isopyrazam, molecular formula: C 20 h 23 f 2 N 3O , Chemical name: 3-difluoromethyl-1-methyl-N-[1,2,3,-tetrahydro=9-(1-methylethyl)-1,4-methanonaphthalen-5-yl] -1H-pyrazole-4-carboxamide. [0003] Pyrafenapyramide is a pyrazole fungicide, a new type of systemic fungicide with spectrum, protective and therapeutic activities. [0004] Carbendazim (Carbendazim), molecular formula: C 9 h 9 N 3 o 2 , chemical name: 2-(methoxycarbamoyl)benzimidazole. Structural formula: [0005] [0006] Carbendazim is a high-efficiency, low-toxicity, broad-spectrum, systemic fungicide with a long duration of action. It is effective against many Ascomycetes, Deuteromycetes and various basidiomycetes, but not effective against algae. ...
