Bio-efficacy of different insecticides was conducted against aphid on tomato at Navsari Agricultural University, Navsari, Gujarat. The results indicated that thiamethoxam 25 WG 0.008 per cent remained the most effective treatment against aphid followed by dimethoate 30 EC 0.03 per cent. Spiromesifen 22.9 SC 0.028 per cent and indoxacarb 14.5 SC 0.005 per cent were ranked third and fourth effective treatments, respectively. On the other side, Lambda cyhalothrin 5 EC at 0.003 per cent remained the least effective treatment among all the insecticide treatments evaluated in this investigation.

Bio-efficacy of different insecticides against Aphid (Aphis gossypii) on Tomato, (Lycopersicon esculentum Mill)

Studies on bio-efficacy of six insecticides against safflower aphids (Uroleucon compositae theobald) showed that dimethoate 0.03 percent and imidacloprid 0.004 per cent were the most effective treatments for the control of safflower aphids. Highest yield of safflower was recorded in dimethoate 0.03 percent but highest incremental cost benefit ratio was recorded through the application of imidacloprid 0.004 percent followed by dimethoate 0.03 per cent.
