摘要

 Whiteflies (Trialeurodes vaporariorum) are one of the most intricate pests to control in gerbera grown under polyhouse conditions. Whiteflies have shown an ability to develop resistance to many pesticides so an attempt was made to test various pesticide biopesticides combinations. To test the efficacy of some pesticide, biopesticides, their combinations and cow urine extract against whitefly in gerbera an experiment was designed at Badamawala polyhouse, Vikasnagar Dehradun during 2011. An experiment was conducted in polyhouse conditions to evaluate and compare the effectiveness of synthetic pesticides (Imidacloprid-T1 and T2, Acetamiprid-T3 and T4), biopesticides (NeemAzal-T5), their combinations (T6-T1+T5, T7-T3+T5) and extract containing cow urine and garlic paste (T8). Whitefly population was assessed by randomly selecting 5 flowers along with stem and leaves for each replicate just before the spray (pre count) and 1st, 5th, 7th and 10th day after spray (post count). Monitoring the population during the test period revealed that all the treatments were found superior over the control as per mean whitefly population count. In addition the spray of cow urine extract also showed results parallel with the treatment T5. Besides the extract of cow urine fermented with garlic extract showed good efficacy against white fly suggesting a prospect for organic production of gerberas in India.
