| Abstract:
Flat headed borer, Sphenoptera dadkhani Obenberger is a serious pest and is responsible for the destruction of peach orchards in the Punjab. Maximum adult emergence of S. dadkhani (94.3%) was recorded from mid March to mid May. Adult emergence was also observed in the second fortnight of June and first week of September. For the control of S. dadkhani a trial with seven treatment times (February, June, October, February and June, February and October, June and October, and February-June-October per year) with two insecticides (chlorpyriphos and lindane each at 0.04%) was conducted during 2001 to 2003. The results revealed that three applications made during February-June-October registered the minimum incidence of flat headed borer with chlorpyriphos. | |
