Abstract

The invention discloses an antibacterial composition containing coumoxystrobin and bromothalonil. The antibacterial composition is prepared from coumoxystrobin and bromothalonil in a weight ratio of 5:1-1:35 as effective ingredients, and further comprises auxiliaries which are permitted to use and accepted in the pesticide science. The composition can be wettable powder, suspending agents, missible oil, emulsion in water, water dispersible granules or microemulsion. According to the antibacterial composition, the action mechanisms of the effective ingredients, namely coumoxystrobin and bromothalonil are completely different, combination of coumoxystrobin and bromothalonil can act on multiple sites of pathogenic bacteria with synergized effect, so that the bacteriocidal spectrum can be enlarged, the prevention effect can be improved, the pesticide dosage can be reduced, generation of pesticide resistance can be delayed, and the resistance risk can be reduced. The antibacterial composition is used for preventing and controlling multiple branch diseases on fruit trees and forests, can be used for preventing and controlling multiple vegetable and fruit tree diseases, such as alternaria leaf spots, scab, anthracnose and the like, and is especially suitable for apple rot, apple trunk canker, cherry gummosis, walnut branch rot and other diseases.

Description

technical field [0001] The invention relates to a bactericidal composition containing syringoxystrobin and bromothalonil, and its application in preventing and treating fruit trees, forest tree branch diseases and vegetable 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...
