Field experiments were carried out in six locations at farmer's fields of Vikasnagar, block of Dist. Dehradun (Uttarakhand) during summer 2010 and 2011 with F₁ cucumber hybrid “Malini” to find out the impact of IPM modules against fruit fly, Bactrocera cucurbitae, red pumpkin beetle, Aulacophora foveicollis and fruit rot, Choanephora cucurbitarum. These revealed that IPM module (M₂) proved to be most effective with lowest incidence of various pests. The maximum fruit yield i.e. 356.33 and 355.45 q/ha was found in the same module during 2010 and 2011, respectively. The studies also showed that net return was also higher. It could be concluded that judicious use of pesticides alongwith seed treatment and other IPM strategies kept the pests population below the economic threshold level besides giving higher level of productivity.
