What methods can control navel orange fruit drop caused by insect damage? Please provide guidance.
Navel orange fruit drop caused by insect damage is mainly due to damage by fruit-boring moths. The severe damage occurs in the later stage, because earlier control combined with other pests and diseases achieved simultaneous control, and production habits have formed such that after September, pesticides are rarely used, and some growers even stop spraying altogether.
The last generation of fruit-boring moths in September will cause a large number of half-yellow fruit drop, causing irreparable losses to production. In large-scale production, the main approach is to seize mid-September and spray with 3000-fold diluted decis or lambda-cyhalothrin. Especially in areas where peach trees and navel oranges are interplanted, even more attention should be paid to controlling the last generation of fruit-boring moths.
