The Chinese herbal medicinal sterilizing agent can effectively control the occurrence of the branch disease of the fruit tree, can promote the rapid healing of scars, and can meet the technical requirement on preventing and controlling the branch disease of the fruit tree, and relevant technologies and products are suitable for conditions of the fruit trees such as significant different distribution geographic positions and ecological environments and complicated and variable weather types.

Description

technical field

[0001] The invention relates to a Chinese herbal medicine fungicide and its application in preventing and treating fruit tree branch diseases, and belongs to the field of Chinese herbal medicine botanical fungicides and technical applications. Background technique

[0002] Branch disease is one of the main diseases of fruit trees, and in recent years, its incidence and harmfulness have increased year by year, becoming a major disease that endangers fruit production. Fruit tree branch diseases include rot, branch ring disease, gummosis, dry rot, canker, branch blight and other diseases. Among them, apple tree rot disease mainly harms the main branches and side branches of apple trees, causing apple trees to lose weight. In recent years, with the popularization and popularization of fruit bagging technology, apple tree branch ring spot has become more and more serious. Tree species such as Fuji and Red Star The disease is the most serious, and the rate of dise...
