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

Embodiment 1

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

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

Embodiment 2

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

[0047]Add 3g of azoxystrobin, 12g of oxaflucondone, 3g of sodium lauryl sulfate, 4g of diffusing agent NNO, 5g of white carbon black, and kaolin to 100g of the mixture and perform jet milling to obtain 15% mass percent of azoxystrobin as the active ingredient · Oxafluconone wettable powder.

Embodiment 3

[0048] Example 3: 14% azoxystrobin·oxaflucondone wettable powder (1:6)

Abstract

The invention discloses a sterilizing composition containing mepanioyrim and famoxadone and an application thereof. According to the sterilizing composition, the mepanioyrim and the famoxadone serve as main active ingredients, wherein the mass ratio of the mepanioyrim to the famoxadone is 1-70:1-50. The sterilizing composition can be applied to prevent and treat cereal diseases, fruit tree diseases and vegetable diseases, has a high synergetic effect, overcomes and delays the germicide resistance of germs and is high in sterilizing speed and long in lasting period, application cost is reduced, and the preventing and treating effect is obviously better than the single-germicide effect. The sterilizing composition can be used for preventing and treating fungal diseases on crops, and particularly can be used for preventing and treating fungal diseases such as gray mold, brown rot, scab, powdery mildew, rust, glume blight, net blotch, downy mildew and late blight, and the effect is better than the single-germicide effect.

Description

Technical field: [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with azoxystrobin and oxaflucondone as main active ingredients and its application. Background technique [0002] Mepanioyrim, chemical name: 4-methyl-N-phenyl-6-(1-propynyl)-2-pyrimidinamine, molecular formula: C 14 h 13 N 3 . The structural formula is as follows: [0003] [0004] Mechanism of action: 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 bacteria entering the host plant and causing necrosis of the host tissue. Mainly prevent and control apple and pear scab, cucumber, grape, strawberry and tomato gray mold, peach, pear and other brown rot. Azoxystrobin has no cross-resistance with triazoles, dithiocarbamates, benzimidazoles and Dito...
