Abstract :

Studies on evaluation of efficacy of biorationals against thrips on carnation were conducted during 2013 in an naturally ventilated polyhouse at Hi-tech horticulture unit, Saidapur Farm, MARS, UAS, Dharwad. L. lecanii @ 2 g/l emerged as the best treatment by providing the highest percent protection over control followed by B. bassiana @ 2 g/l and NSKE @ 5%. Lowest per cent protection was seen in P. lilacinus @ 2 g/l treated crop. L. lecanii @ 2 g/l recorded maximum yield, highest net return and cost- benefit ratio followed by NSKE @ 5%.
