Effect of different non-chemical and chemical measures against onion thrips

Naima Din, Misbah Ashraf and Shahbaz Hussain

The effect of insecticides (Imidacloprid 200SL, 250 ml/acre; Imidacloprid + Fipronil 80 WG, 60 gm/acre, Chlorfenapyr 36SC, 50WDG, 100ml/acre and leaf extracts of (Nerium indicum, Calotropis procera and Datura stramonium seed extract of each at 5%) were evaluated against Thrips tabaci in farmer’s field. Data recording intervals were 24, 48, 72-hours and 7-days. The results revealed that maximum population reduction was observed in Imidacloprid + Fipronil 80WG (94.28%) followed by Chlorfenapyr 50WDG (93.37%), Chlorfenapyr 36SC (91.26%) and Imidacloprid 200SL (85.06%) and where mean population of thrips per five plants were recorded 2.33, 2.33, 2.73 and 6.26, respectively. After 24-hours of data recording interval among the botanicals, D. stramonium gave significantly lower population of thrips (9.700 per five plants) and highest reduction percentage (82.36) after 48-h of intervals followed by C. procera and N. indicum with mean population 11.36, 13.90 showing reduction percentage 79.33 and 74.76, respectively.
