Abstract
The effect of nine surfactants on the activity of oxytetracycline hydrochloride (OCT) was investigated against Lipaphis erysimi Kalt feeding on cabbage plants. All the surfactants, except Emulgator EL and Emulgator IP, at 0.1% increased the efficacy of OTC at 0.25% and the maximum reduction of 83.93% in fertility was observed for the combination OTC+Arkopal N-110. The nymphal development was delayed by various treatments. The treated adults were lighter in weight and smaller in size compared to the control insects. No photoxicity was observed in any case.Keywords
