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 de...

Six compounds (IBA, chlorogenic acid, cytokinine, GA3, alar B-9 and maleic hydrazide) belonging to four different categories of plant growth hormones were used to study their effect on carbohydrate content in L. erysimi. The second instar nymphs (48 hr old) were given both dipping and leaf surface treatment with 1024 ppm concentration of compounds for two time intervals i.e. 48 and 96 hr. The c...
