EFFICACY OF DIFFERENT BOTANICALS AND A NEW CHEMISTRY INSECTICIDE AGAINST Bemisia tabaci (HEMIPTERA: ALEYRODIDAE) ON SUNFLOWER (Helianthus annuus L.)

Vulnerability to a number of insect pests is one of the major constraints towards the successful production of sunflower. among these insect pests, whitefly is considered key pest that contributes huge losses to sunflower yield. the present study was conducted at new developmental farm (ndf), the university of agriculture peshawar, (34.01° n, 71.53° e) pakistan during the years 2012 and 2013 to determine the efficacy of different botanicals and a new chemistry insecticide against whitefly associated with sunflower hysun-33. whitefly population was recorded a day before and 1, 2, 3 and 7 days after application of each spray material on the crop. the results showed that low population of whitefly was recorded in the emamectin benzoate treatment while among the botanicals, datura alba was the most effective treatment in terms of population decline of whitefly, which was followed by azadirachta indica oil and a. indica seed extract. highest pest population was recorded on untreated check plots. the present results indicated that plant derived extracts and oil have the potential to be used for the successful control of whitefly on sunflower.
