ABSTRACT
Bitter gourd (Momordica charantia L.) is one of the most important vegetable crop of warm season. Various number of insect pests attack on this crop but whitefly (Bemisia tabaci Genn.) is one of them. An investigation was carried out at farmar’s field in Malam jaba Swat during Kharif crop 2018 to evaluate the effectiveness of synthetic and botanical insecticides against insect pests of bitter gourd i.e Whitefly Significant differences were observed among all the treatments as compared to untreated plot. Results revealed that Flonicamid 50WG (0.3g/l) was significantly better in minimizing the whitefly population, followed by Diafenthiuron 50WP (0.6g/l), Diptrex (Trichlorofom) 80-SP at 1250 gm/ha, Thiamethoxam 25 WG (0.2g/l), Chinaberry (200g/l), Garlic (20g/l), and Neem oil (2% cont). Similarly, highest yield (1556.38 kg/ha) and cost benefit ratio (1:9) was observed in Flonicamid 50WG (0.3g/l) treated plots. From the above study, it is concluded that all the insecticides reduce the population whitefly and increases net production of the crop. But chemical insecticide Flonicamid 50WG (0.3g/l) is recommended against various sucking insect pests.
