VARIETAL SCREENING OF CHICKPEA AND THE EFFICACY OF DIFFERENT INSECTICIDES AGAINST CHICKPEA POD BORER HELICOVERPA ARMIGERA (HB)

Abstract

Two experiments were conducted at the Research Farms of Agriculture Research Institute Ratta Kulachi Dera Ismail Khan to test six varieties of gram (KK-1, CM-88, CM-72, C-3, C-40 and Piadar) for their tolerance against gram pod borer and to assess comparative efficacy of five insecticides (Thiodan 40EC, Lorsban 40EC, Ripcord 10EC, Nurell-D (Chlorpyrifos + Cypermethrin 50 + 500 g/L EC) and Methomy 45 WP) against gram pod borer Helicoverpa armigera (Hubner) during the year 2003-04. Gram variety CM-72 was found significantly more tolerant to the attack of gram pod borer followed by KK-1. Maximum pod borer infestation was found in variety CM-88. All the tested insecticides significantly reduced the infestation of gram pod borer as compared to control plots. However, Methomyl was found most effective against the tested pest under field conditions.
