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

The invention discloses a bactericidal composition containing boscalid and myclobutanil and application thereof. The bactericidal composition uses boscalid and myclobutanil as main active ingredients, wherein the weight ratio of boscalid and myclobutanil 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 present invention can be used to prevent and treat fungal diseases on crops, especially can be used to prevent and control powdery mildew, gray mold, sclerotinia, rot, rust, scab, gray spot, brown spot, smut, etc. For 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 boscalid and myclobutanil as main active ingredients and its application. Background technique [0002] Boscalid is a new type of nicotinamide fungicide developed by BASF, Germany, chemical name: 2-chloro-N-(4'-chlorobiphenyl-2-yl) nicotinamide, molecular formula: C 18 h 12 Cl 2 N 2 O. The structural formula is as follows: [0003] [0004] The fungicide has a wide bactericidal spectrum and is active against almost all types of fungal diseases. It is very effective in the control of powdery mildew, gray mold, sclerotinia and various rot diseases, and is also effective against other fungal resistant bacteria. , for canola, beans, bulb vegetables, mustard greens, carrots, apples, lettuce, peanuts, potatoes, stone fruits, strawberries, nuts, cabbage, cucumbers, mint, peas, root vegetables, sunflowers, grapes, turf, other fruit ...
