Antibacterial composition containing boscalid and prochloraz-manganese chloride complex and application of composition

Abstract

The invention discloses an antibacterial composition containing boscalid and prochloraz-manganese chloride complex and application of the composition. According to the antibacterial composition, boscalid and prochloraz-manganese chloride complex serve as main effective components, and the weight ratio of boscalid to prochloraz-manganese chloride complex is (1-70):(1-50). The antibacterial composition can be used for preventing cereal, fruit tree and vegetable diseases, has a high synergistic effect, overcomes and delays virus insecticide resistance, is high in sterilization speed and long in persistence, reduces application cost, and is better in prevention effect compared with single medicament application. The composition can be used for preventing fungal diseases on crops, can be particularly used for preventing powdery mildew, gray mold, rape sclerotinia sclerotiorum, the rotten disease, garlic leaf blight, tobacco brown spot, pepper gray mold, watermelon blight, the mushroom damp disease, grape anthracnose, orange penicilliosis, penicillium digitatum, mango anthracnose and other fungal diseases, and is better in effect compared with single medicament application.

Description

technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition with boscalid and prochloraz manganese salt 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,...

AI Technical Summary

Problems solved by technology

[0008] But wheat powdery mildew, gray mold, rape sclerotinia and rot, garlic leaf blight, tobacco red spot, pepper gray mold, watermelon wilt, mushroom wet bulb, grape black spot, citrus penicillium , green mold, mango anthracnose, etc. are more serious, causing catastrophic losses to agricultural production. Although boscalid and prochloraz manganese salt have a relatively ideal control effect on some diseases, in practical applications , but 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. The difficulty of prevention and control is increasing; the second is the current abnormal climate, which provides certain conditions for the outbreak of the disease; the third is the selective influence of long-term chemical drugs, which makes the resistance of pathogenic bacteria increase year by year under the continuous pressure of drug selection. The control effect is greatly reduced

In summary, the current plant disease control is facing major challenges
