Abstract The field experiments were carried out at six locations in farmer's fields of Vikasnagar, block of Distt. Dehradun(Uttarakhand) during summer season of 2010 and 2011 with F1 cucumber hybrid “Malini ” to find out the impact of various IPM modules against fruit fly, Bactrocera cucurbitae, red pumpkin beetle, Avlacophora foveicollis and fruit rot, Choanephora cucurbitarum. The investigations revealed that IPM module (M2) proved to be most effective treatment in which lowest incidence of various pests was recorded followed by module (M1) during both the years. The maximum fruit yield i.e. 356.33 and 355.45 q/ha was found in module (M2) respectively, during 2010 and 2011 which was significantly superior over all other IPM modules. Net return was also higher in module (M2) with Rs. 162365.00/ha in 2010 and 161125.00/ha during 2011. The module (M1) was the next effective treatment in which mean net return of Rs. 142790.00. It is concluded that judicious use of pesticides applied in module (M2) alongwith seed treatment and other IPM strategies kept the pests population below the economic threshold level besides giving higher level of productivity from cucumber crop.
