Effect of Integrated Pest Management Practices in Brinjal (Solanum melongena L)

Abstract

For the management of insect pests and diseases of brinjal, farmers are using conventional as well as novel pesticides including carbendazim, cypermethrin 25 EC, spinosad 2.5 percent SC and indoxacarb 15.8 SC. The large scale use of pesticides has caused many environmental problems like pesticide poisoning, insecticide resistance, resurgence of insect pests, effect of non-target organisms and pesticide residue which led to the scientist on alternative methods of pest control in brinjal. The objectives of the study were to minimize the use of chemical pesticides and establish the use of eco-friendly management practices. For this front line demonstrations were organized during 2011–12 and 2012–13 to evaluate the feasibility and economic viability of recommended practices for the management of pests (insects and diseases) of brinjal under real farm condition. On the basis of result obtained from assessment of recommended technology, frontline demonstrations were organized to disseminate the recommended practices. Components of IPM technology used were Seedling root treatment for 3 hour with imidacloprid (1ml/litre) + Soil application of Trichoderma + installation of pheromone traps @ 35/ha + Mechanical removal of infected shoots and fruits + Spraying of NSKE 4 per cent. The recommended technology was found to offer an alternative to pesticides and was feasible, economically viable, environmentally safe and effective for pest management in brinjal.
