Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a biological fungicide for preventing and curing apple tree rot and a preparation method thereof. Background technique [0002] Apple tree ring disease, also known as rough skin disease and ring fruit rot disease, is one of the important diseases in apple production. Apple ring disease includes dry ring disease of apple branches and fruit ring disease. At present, the occurrence and damage of apple ring disease in our country are becoming more serious. It not only harms apple fruit and reduces production, but also harms the branches and stems, causing ulcers on the branches and stems, weakening the vigor of the tree, reducing the results, leading to a decline in yield and causing greater economic losses. [0003] Chinese patent CN100431420C discloses a plant disease control agent. The components and their weight percentages are respectively: Zhongshengmycin 1%-10%, saliva...
