Example Embodiment

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

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

Example Embodiment

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

[0047]Add 3 g of pyraclostrobin, 12 g of azoxystrobin, 3 g of sodium lauryl sulfate, 4 g of diffusing agent, 5 g of white carbon black, and kaolin to 100 g of the mixture and carry out jet milling to obtain 15% pyrazole by mass percentage as the active ingredient Nafluprodil·Azoxystrobin wettable powder.

Example Embodiment

Abstract

The invention discloses a fungicidal composition containing isopyrazam and mepanipyrim and an application thereof.According to the fungicidal composition, isopyrazam and mepanipyrim serve as main active ingredients, wherein the mass ratio of the isopyrazam to the mepanipyrim is (1-70):(1-50).The fungicidal composition can be applied to controlling cereal diseases, fruit tree diseases and vegetable diseases, and has the high synergistic interaction effect, the pesticide resistance of pathogenic bacteria is overcome and delayed, the sterilization speed is high, the lasting period is long, application cost is reduced, and the control effect is obviously better than the use effect of a single pesticide.The fungicidal composition can be used for controlling fungi diseases on crops and particularly can be used for controlling fungi diseases such as wheat powdery mildew, apple scabs, pear scabs, grape gray mold and tomato gray mold, and the effect is remarkably better than the use effect of the single pesticide.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with pyraclostrobin and azoxystrobin 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] Mepanipyrim, molecular formula: C 14 h 13 N 3 , Chemical name: N-(4-methyl-6-prop-ynylpyrimidin-2-yl)aniline. Structural formula: [0005] [0006] Azoxystrobin has a unique mechanism of action, which is to inhibit the protein secretion of pathogenic bacteria, including reducing the level of some hydrolytic enzymes. It is speculated that these enzymes are related to the pathogenic b...
