Abstract


Supervised field trials were conducted to evaluate Kinadongold (Phosphamidon 40% + imidacloprid 2% SP) as foliar application for its bioefficacy against sucking insects, phytotoxicity and effect on natural enemies on cotton in Tamil Nadu Agricultural University, Coimbatore. Two season field experiments on cotton revealed that the higher dose of Kinadongold (700 g ha-1) recorded 76.43, 73.28, 76.06 and 69.66 per cent reduction over untreated check for leafhoppers, thrips, aphids and whiteflies, respectively and it was followed by with on par Kinadongold (600 g ha-1), that recorded 74.02, 72.33, 74.34 and 66.77 per cent reduction over untreated check for leafhoppers, thrips, aphids and whiteflies, respectively. There was an initial setback in the population of natural enemies in the Kinadongold treated plots, but it started increasing gradually. Kinadongold did not cause any phytotoxic symptoms even up to a dose of 2400 g ha-1 on cotton.
