Abstract

The invention discloses a method for comprehensive prevention and control of dragon fruit brown rot based on precise pesticide application and its application. The present invention is based on the continuous research on the catastrophic law of dragon fruit brown rot and the selection of fungicides with long-lasting effect and good systemic property. In terms of precise pesticide application, by moving the disease prevention and control period forward, reducing the source of initial infection, and gradually replacing diseased fruit-bearing branches, the fruit damage rate can be reduced, and the orchard with serious dragon fruit brown rot can be effectively controlled. After years of field tests and demonstrations, the method of the invention can effectively control the occurrence and damage of dragon fruit brown rot in the field, and greatly reduce the frequency of spraying and labor and drug costs.
