Abstract

Diamondback moth [Plutellaxylostella(L.)] is the most serious and widely distributed pest of cauliflower (Brassica oleraceavar.botrytis) in India, attacking the crop from the nursery level onwards causing up to 52 per cent losses in marketable yield. To manage the menace farmers were using conventional as well as novel pesticides including Flubendiamid, 20 per cent WG, Spinosad 2.5 per cent SC and Fipronil 0.30 per cent GR. The problems of insecticide resistance as well as the environmental concerns and consumer health hazards associated with insecticide residues in plant material have focused attention on alternative methods for the management of diamondback moth (DBM) in cauliflower. With the objectives to minimize the use of chemical pesticides and establish the use of ecofriendly bio-control agents, an assessment and front line demonstrations were organized during 2009 and 2010 to evaluate the feasibility and economic viability of recommended bio-control agent i.e. Beauveriabassianafor containing DBM in cauliflower under real farm condition. On the basis of result obtained from assessment of recommended technology, frontline demonstrations were organized to disseminate the recommended practice [foliar spray of Beauveriabassiana(1x1010 conidia/ml)] a myco-insecticide (@600 ml/ha) amongst the farmers. The recommended technology was found to offer an alternative to insecticides and was feasible, economically viable, environmentally safe and effective for management of DBM in cauliflower
