Problems solved by technology

[0004] At present, it is found that the prevention and control of plant pathogens is becoming more and more difficult. The main reasons are as follows: First, 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. Second, the current abnormal climate provides certain conditions for the outbreak of the disease; third, the long-term selective influence of chemical drugs makes the resistance of pathogenic bacteria increase year by year under the continuous pressure of drug selection. The effect of prevention and treatment is greatly reduced
In summary, the current plant disease control is facing major challenges

Abstract

The invention discloses a bactericidal composition containing cyclohexastrobin and enoxistrobin and application thereof. The bactericidal composition uses cyclohexastrobin and enoxastrobin as main active ingredients, wherein the mass ratio of cyclohexastrobin to oxastrobin is 1:50-70:1. 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 present invention can be used to control fungal diseases on crops, especially can be used to control tomato gray mold, pear scab, wheat rust, wheat powdery mildew, rice sheath blight, cucumber powdery mildew, grape downy mildew, tomato Early blight and other fungal diseases, the effect is better than a single dose.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with cyclohexasulfame and enoxastrobin as main active ingredients and its application. Background technique [0002] Molecular formula of cyclohexasulfame: C 13 h 13 CIF 3 NO 3 S. Chemical name: N-(2-trifluoromethyl-4-chlorophenyl)-α-oxocyclohexylsulfonamide. It has strong preventive, therapeutic and osmotic activities, and has high persistence. The field test results show that it can effectively control Botrytis cinerea, rape sclerotinia, cucumber brown spot and scab. [0003] Molecular formula of enoxastrobin: C 21 h 20 Cl 2 N 3 o 3 . Chemical name: (E, E, E)-N-methyl-2-[((((1-methyl-3-(2,,6,-dichlorophenyl)-2-propenyl)imino )oxy)methyl)phenyl]-2-methoxyiminoacetamide. Enoxastrobin has a wide bactericidal spectrum, high activity, preventive and therapeutic effects, and has good compatibility with environmental organisms. ...
