Method for controlling apple tree canker

Abstract

The invention discloses a method for controlling apple tree canker, comprising the following steps: (1) spraying a canker pathogen inhibitor on a whole fruit tree after harvesting apples in autumn; (2) thinning and shaping the fruit tree in winter, cleaning up an orchard, spraying the canker pathogen inhibitor again in the whole orchard, and spraying a fruit tree wintering protection agent in thewhole orchard after one week interval; (3) inspecting the tree body, removing and cleaning up found scabs, coating the site, where the scabs are removed, with a canker pathogen inhibitor, and conducting sealed cladding on the surface of the scab site by a transparent plastic bag, and for serious canker, besides the above steps, injecting fruit tree nutrient fertilizer into scab sites for nutrientsupplement by a fruit tree liquid conveying device; and (4) in spring of a next year, spraying a canker pathogen inhibitor in the whole orchard before germination of the fruit trees. The method of theinvention can effectively solve the incidence of fruit tree canker and reduce the probability of secondary infection and recurrence of fruit tree disease.

Description

technical field [0001] The invention relates to the field of prevention and control of fruit tree diseases and insect pests, in particular to a method for preventing and treating apple tree rot. Background technique [0002] Apple tree rot disease, commonly known as stinky skin disease and skin rot disease, is a widespread worldwide disease and the most threatening and devastating disease in apple producing areas in my country. The disease can cause apple trees to weaken and branches to die , resulting in insufficient nutrient supply of fruit trees, and in severe cases, a large number of fruit trees died, and even the garden was destroyed. There are two peaks of apple rot disease in a year, one in spring and one in autumn. In recent years, the occurrence of rot disease has become more and more serious, and it has become the main disease affecting apple production. The disease has significantly reduced apple production. It can be seen that the prevention and treatment of app...

Problems solved by technology

Because this method can only be implemented after the scab is found, it is usually too late, and the onset of the rot disease is relatively serious. Even if it is cured, the problem of secondary infection and recurrence of the scab will still occur. The wound area caused is large, which is not conducive to the wound healing and recovery of the tree body, affects the nutrient transportation of the tree body, causes the apple tree to weaken, and the disease resistance declines, affecting the normal growth, single fruit quality and fruit yield of the fruit tree
