Abstract

The invention discloses a xinjun'an and propiconazole-containing bactericidal composition. The composition contains xinjun'an and propiconazole which serve as effective components; the weight ratio of the xinjun'an to the propiconazole is (2: 1) to (1: 30); the composition further can contain pesticidally available and acceptable auxiliary materials; the dosage form of the composition can be wettable powder, a suspending agent, missible oil, emulsion in water, water dispersible granules or microemulsion. According to the bactericidal composition disclosed by the invention, the action mechanisms of the effective components are completely different; when compounded, the effective components can act on multiple sites of pathogenic bacteria, so that synergistic interaction is realized, the bacteriocidal spectrum is expanded, the prevention effect is enhanced, the use amount of pesticides is reduced, the generation of the drug resistance is delayed, and the resistance risk is reduced. The bactericidal composition is used for preventing and treating various branch diseases on fruit trees and forests, is particularly suitable for diseases such as apple rot, apple branch ring spot, apple dry rot, cherry bleeding disease, peach tree bleeding disease, blueberry branch rot, walnut branch rot, poplar branch rot and poplar canker disease, and can be further used as a sealing agent for grafting and pruning of the fruit trees and the forests.

Description

technical field [0001] The invention relates to a bactericidal composition containing octoprodil and propiconazole, and its application in the prevention and treatment of fruit tree and forest tree branch diseases, which belongs to the technical field of pesticide prevention and control. Background technique [0002] Branch disease is one of the main diseases of fruit trees and trees, and in recent years, its incidence and harmfulness have increased year by year, becoming a major disease that endangers fruit industry and forestry production. Diseases of branches and trunks of fruit trees and forest trees include rot, branch ring disease, gummosis, dry rot, canker, branch blight and other diseases. Among them, apple tree branch ring disease has grown with the fruit bagging technology The popularity and popularization of apple trees is becoming more and more serious, and the tree species such as Fuji and Red Star have the most severe disease, and the diseased strain rate reache...
