Abstract
Okra is infested by various sucking insect pests among which jassids (Amrasca biguttula biguttula), aphids (Aphis gossypii), and whiteflies (Bemisia tabaci) are the major ones. Tolfenpyrad, belonging to the pyrazole class of insecticides is used against Hemiptera, Coleoptera, Diptera, Lepidoptera, Thysanoptera and Acarina. In this study tolfenpyrad 15% EC @ 125 and 150g a.i./ha showed better performance against sucking pest complex of okra. The observations on the phytotoxicity symptoms (viz., leaf injury, wilting, vein clearing, necrosis, epinasty and hyponasty etc.), if any, with tolfenpyrad 15% EC (300g a.i/ha) are also included. It is concluded that tolfenpyrad @ 125 and 150g a.i./ha might be recommended for okra and it is also safer to natural enemies.
