A sterilization composition containing fluazinam and pyraclostrobin and applications thereof

Abstract

The invention discloses a sterilization composition containing fluazinam and pyraclostrobin and applications thereof and belongs to the technical field of pesticides. The composition adopts the fluazinam and the pyraclostrobin as main effective components, wherein the weight ratio of the fluazinam to the pyraclostrobin is 1-70:1-50. The composition can be applied for control of fungal diseases of cereals, fruits, melons or vegetables, and can be particularly used for control of rice blast, banded sclerotial blight, scab disease, powdery mildew, anthracnose, venturia nashicola, penicilliosis, blight, foliage blight, rust, downy mildew, brown spot, club root, damping-off, gray mold, black spot, crown rot and spot disease. The composition has high synergistic effects, overcomes and delays drug resistance of germs, expands the control spectrum, is high in sterilization speed, long in lasting period and capable of reducing the application cost, and has control effects which are obviously better than that when a single pesticide is used.

AI Technical Summary

Problems solved by technology

[0009] Leaf blight, rust, powdery mildew, downy mildew, blight, anthracnose, sore dementia, brown spot, clubroot, blight, gray mold, etc. Scab, black spot, rice blast, crown rot, and spot disease are becoming more and more serious, and the difficulty of control is also increasing: on the one hand, with the change of planting structure, economic crops such as melons, fruits, and vegetables The planting area is gradually expanding, and the degree and number of diseases have increased, making it more difficult to control; on the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous chemical selection, and the control effect of a single agent is greatly reduced. Disease control faces major challenges
