The occurrence of kiwi brown rot is related to climatic conditions. Kiwifruit brown rot is a common disease in kiwifruit vines and fruits from the late growth stage to storage. So, how should kiwi brown rot be controlled?
1. Cultivate strong trees and enhance resistance. Strengthen the management of the park, pay attention to the drainage of the ditch, rational fertilization, and apply some potassium sulfate and manganese sulfate to promote the vegetative growth and fruit development of the plant.
2. Winter pruning, clearing, fertilization and other work must be done seriously. Ground foliage and fruit should be thoroughly removed to reduce the source of infestation at the beginning of the year. For the dead branches of the tree that have not been trimmed, it is necessary to check and repair.
3. Prompt spraying at the right time. After the end of the work of the Qingyuan Garden in the winter, it should be combined with other pests and diseases to spray a 5-6 degree stone sulfur mixture. Before and after the flowering period to the young fruit expansion period, 50% methyl thiophanate, carbendazim, dextran and other wettable powder 800 times solution can be used to spray the branches, leaves and fruits 2 to 3 times, and the effect is good.
