Bactericidal composition containing benthiavalicarb and cyproconazole and application thereof

Abstract

The invention relates to a bactericidal composition containing benthiavalicarb and cyproconazole and an application thereof. The bactericidal composition containing benthiavalicarb and cyproconazole takes benthiavalicarb and cyproconazole as main active components, and the weight ratio of benthiavalicarb to cyproconazole is 1-70:1-50. The invention also discloses the application of the bactericidal composition in preparation of drugs for prevention and control of resistant plant fungal diseases; the bactericidal composition can be applied for prevention and control of cereal, fruit and vegetable diseases, has a relatively high synergistic effect, overcomes and delays drug resistance of pathogenic bacteria, is rapid in sterilization speed and long in lasting period, reduces the application cost, and has the prevention and control effects obviously better than those of single agents. The bactericidal composition can be used for preventing and controlling the fungal diseases on crops, especially can be used for preventing and controlling the fungal diseases such as late blight, downy mildew, rust disease, powdery mildew, leaf spot and leaf spot, and has the effects better than those of single agents.

Description

Technical field [0001] The invention relates to a bactericidal composition and uses thereof, in particular to a bactericidal composition containing befenthiamine and ciproconazole and applications thereof. Background technique [0002] Benthiavalicarb-isopropyl, molecular formula: C 18 H 24 FN 3 O 3 S, chemical name: [[(6-Fluorobenzothiazol-2-yl)-ethylcarbamoyl]-2-methylpropyl] isopropyl carbamate. [0003] Benthiazamide has a good bactericidal activity against Phytophthora, and has a good inhibitory effect on the formation of sporangia and the germination of sporangia at low concentrations, but it has a good effect on the release of zoospores and the movement of zoospores. No effect. In the field test, Benthiozamide was used at a lower dose (25~75g a.i. / hm 2 ) Can effectively control late blight of potatoes and tomatoes, downy mildew of grapes and other crops. [0004] Cyproconazole (Cyproconazole), chemical name: 2-(4-chlorophenyl)-3-cyclopropyl-1-(1H-1,2,4-triazol-1-yl)butan-2- ...

AI Technical Summary

Problems solved by technology

[0007] 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
