A bactericidal composition containing difenoconazole and biological antibacterial substance hsaf and its application

Abstract

The invention discloses a difenoconazole and biological antifungal substance HSAF (heat stable antifungal factor) containing fungicidal composition and application thereof. The fungicidal compositiontakes difenoconazole and HSAF as main effective components, and a mass ratio of difenoconazole to HSAF is 1:25-25:1. The fungicidal composition has synergistic effects in the above ratio range, drug resistance of germs is overcome and retarded, and high fungicidal speed, great prevention effects, long efficacy lasting period and low application cost are realized. The fungicidal composition is capable of preventing and controlling various crop fungal and oomycetes diseases and evidently superior to single agents in prevention and control effects on fungal diseases such as black spot, rot, scab,anthracnose, rust disease and the like of fruit trees and vegetables.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, and in particular relates to a bactericidal composition with difenoconazole and a biological antibacterial substance HSAF as main active ingredients and an application thereof. Background technique

[0002] In recent years, with the improvement of people's living standards, the structure and mode of planting have changed. The planting area of ​​green and efficient fruit trees, vegetables and other horticultural crops has gradually expanded, the varieties have become increasingly rich, and the economic output value has increased rapidly.
