dc.description.abstractOkar, being an important vegetable, grown exclusively in and around Ranchi for about three quarters of an year.It is attacked by a number of insect pests,mites namatodes during different growth stages. The major insect pests of okra in and around Ranchi include aphids(Aphis oossvpii Glow), Jassids (Amrasca biguttula biguttula ishida), Semilooper (Anomis flava Fabricius),and fruit borer (Earias fabia Stollalis). Field studies were made on the control of pest complex of okra as influenced by chemical seed treatment and need based foliar spray. Seed soaking with monocrotophos and quinalphos exhibited boosting effect on germination.The population of aphid was low in both monocrotophos and quinalphos seed treatments upto 45 days. All the sprays remained at per but they were better than the control against aphid. Seed soaking in monocrophos registered low jassid population up to 45 days. All the sprays remained at par but they were better than the control against aphin.Seed soaking in monocrotophos registered low jassid population up to 45 days. Lowest jassid population was observed with monocrotophos seed treatement followed by sprays of fevalerate. Aganst semilooper, all the insecticides were found to be affective. The lowest borer infested okra fruits was obtained with seed soaking in monocrotophos followed by need based sprays of fluvalinate. Higher number of fruits as well as yield were obtained in the treatement seed soaking in monocrotophos +need based spraying of monocrotophos.en_US
