Abstract

The invention relates to a compound synergistic bactericidal composition for preventing and treating main diseases of tomatoes and pear trees and an application thereof. Active ingredients of the pesticide composition comprise pydiflumetofen and an active ingredient B, and the active component B comprises one of a substituted aniline bactericide and bacillus subtilis BAB-1. The pesticide composition disclosed by the invention is applied to prevention and treatment of main diseases of tomatoes and pear trees, such as gray mold, early blight, leaf mold, gray leaf spot, scab, ring spot and blackspot, and the bactericidal composition has the advantages of good fast-acting property and persistence, novel action mechanism and multiple sites, can effectively delay the occurrence and developmentof drug resistance of pathogenic bacteria, and not only has a protective effect on diseases, but also has a good treatment effect. The compound synergistic composition has the advantages that the dosage is small, and the pollution of medicaments to fruits and the environment is effectively reduced.

Description

[0001] This application is a divisional application of the invention patent application with the application date of 2017.08.14, the application number 201710692451.X, and the invention title "Composite synergistic bactericidal composition and its application for preventing and controlling the main diseases of tomato and pear trees". technical field [0002] The invention belongs to the technical field of pesticides, in particular to a compound and synergistic bactericidal composition for preventing and treating main diseases of fruits and vegetables and its application. Background technique [0003] Adepidyntm belongs to the class of succinate dehydrogenase inhibitor fungicides, and its mode of action is to affect the energy metabolism of cells by acting on complex II (succinate dehydrogenase) of the mitochondrial respiratory chain, thereby Inhibits spore germination, germ tube and mycelium growth of target fungi, showing good protective and therapeutic effects. The fungici...
