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·Cyazofamid WP (1:2)

[0045] 5 g of azoxystrobin, 10 g of cyazofamid, 2 g of detergent LS (sodium p-methoxy fatty acid aminobenzene sulfonate), 4 g of diffusing agent NNO (sodium methylene bis-naphthalene sulfonate), 5 g of white carbon black, The kaolin clay is added to 100 g of the mixture, and the mixture is subjected to jet pulverization to obtain a 15% azoxystrobin-cyfamidazole wettable powder by mass percentage of the active ingredient.

Embodiment 2

[0046] Example 2: 15% Azoxystrobin·Cyazofamid WP (1:4)

[0047]3 g of azoxystrobin, 12 g of cyfamidazole, 3 g of sodium lauryl sulfate, 4 g of diffusing agent NNO, 5 g of white carbon black, and kaolin are added to 100 g of the mixture and air-milled to obtain an active ingredient mass percentage of 15% azoxystrobin. Cyfamid WP.

Embodiment 3

[0048] Example 3: 14% Azoxystrobin·Cyazofamid WP (1:6)

[0049] 2 g of azoxystrobin, 12 g of cyfamidazole, 3 g of sodium lauryl sulfate, 4 g of diffusing agent NNO, 5 g of white carbon black, and kaolin are added to 100 g of the mixture for jet milling to obtain an active ingredient mass percentage of 14% azoxystrobin. Cyfamid WP.

Abstract

The invention discloses a bactericidal composition containing azoxystrobin and cyafamid and application thereof. The bactericidal composition uses azoxystrobin and cyafamid as main active ingredients, wherein the mass ratio of azrastrobin to cyafamid is 1-70:1-50. The bactericidal composition can be applied to the prevention and treatment of cereals, fruit trees, and vegetable diseases, has a high synergistic effect, overcomes and delays the drug resistance of pathogens, has fast sterilization speed, long-lasting effect, reduces application costs, and has good control effect. Significantly better than its single dose use. The invention can be used to prevent and control fungal diseases on crops, especially can be used to prevent and control fungal diseases such as gray mold, brown rot, scab, downy mildew and late blight, and the effect is better than that of a single dose.

Description

Technical field: [0001] The present invention relates to a bactericidal composition and use thereof, in particular to a bactericidal composition with azoxystrobin and cyazofamid as main active components and application thereof. Background technique [0002] Mepanioyrim, chemical name: 4-methyl-N-phenyl-6-(1-propynyl)-2-pyrimidinamine, molecular formula: C 14 H 13 N 3 . The structure is as follows: [0003] [0004] Mechanism of Action: Azoxystrobin has a unique mechanism of action that inhibits protein secretion by pathogenic bacteria, including reducing the levels of some hydrolases, which are speculated to be related to pathogenic bacteria entering host plants and causing host tissue necrosis. The main control is to prevent and control apple and pear scab, cucumber, grape, strawberry and tomato gray mold, peach, pear and other brown rot. Methyl azoxystrobin has no cross-resistance with triazoles, dithiocarbamates, benzimidazoles and acetocarb, so it has excellent ...
