This study evaluated the efficacy of diafenthiuron against potato leafhopper Empoasca fabae Harris during rabi, 2018-19 and 2019-20. Seed treatment with imidacloprid 17.8SL @0.4ml/ l along with foliar spray @150ml/ ha, thiamethoxam 25WG @100g/ ha, diafenthiuron 50WP @700g/ ha, castor oil @250ml/ ha, diafenthiuron 50WP @700g/ ha mixed with castor oil @250ml/ ha and untreated control were the treatments compared. The results revealed that the treatments consisting of first foliar spray of diafenthiuron 50WP @700g/ ha mixed with castor oil @250ml/ ha, and second spray of diafenthiuron 50WP @700g/ ha at 30 and 40 days after planting was the most effective. This treatment also gave maximum tuber yield (10.16±0.11 t/ ha) which is a 43% increase over untreated control with a benefit: cost ratio of 1.62. [ABSTRACT FROM AUTHOR] |
