Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for preventing and controlling the small fruit borer of juicy peach pears. Background technique [0002] In recent years, with the continuous expansion of the area of ​​peach trees and the improvement of drug resistance and other factors, the damage of the small pear borer on peach trees has become more and more serious. The insect has 1-2 generations of moths in peach orchards, and generally the third generation Small pears are harmful to pome fruit, but in recent years, the third generation of mid- and late-maturing peaches has become more and more harmful to peach fruit. The rate of re-growing orchard slice insects is as high as 29%, becoming a dangerous pest in the production of mid-late-maturing peach varieties. At present, the insect has developed a certain resistance to traditional chemical pesticides, resulting in reduced control efficiency. Contents of the...
