Fungicidal composition containing boscalid and benthiavalicarb-isopropyl and application of fungicidal composition

Abstract

The invention discloses a fungicidal composition containing boscalid and benthiavalicarb-isopropyl and application of the fungicidal composition. Boscalid and benthiavalicarb-isopropyl serve as main active ingredients of the fungicidal composition, wherein the weight ratio of boscalid to benthiavalicarb-isopropyl is (1-70):(1-50). The fungicidal composition can be applied to control over diseases of cereals, fruit trees and vegetables, has a high synergistic effect, overcomes and delays the pesticide resistance of fungi, and is high in fungicidal speed, long in lasting period, capable of reducing application cost and obviously superior to single dosages in control effect.

Description

Technical field: [0001] The invention belongs to the field of pesticides, and relates to a bactericidal composition containing boscalid and benthiazil and an application thereof. 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 trees, Prevention and control of vegeta...

AI Technical Summary

Problems solved by technology

[0006] In recent years, powdery mildew, gray mold, sclerotinia, rot, tomato late blight, grape downy mildew, etc. have occurred more seriously, causing catastrophic losses to agricultural production. However, in actual application, it is found that the control of plant pathogens is becoming more and more difficult. The main reasons are as follows: First, with the change of planting structure, economic crops such as melons, fruits and vegetables are planted more and more difficult. The area is gradually expanding, and the degree and number of diseases have increased, making it more difficult to prevent and control; second, the current abnormal climate provides certain conditions for the outbreak of the disease; third, the selective impact of long-term chemical drugs makes The resistance of pathogenic bacteria is increasing year by year under the continuous pressure of agent selection, and the control effect of single agent is greatly reduced

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