Abstract: Two commonly used insecticides, Methamidophos 60SL @ 1000ml/ha and Monocrotophos 40WSC @ 1500 ml/ha were evaluated on Amrasca devastans L. during 1999 on Pusa Swani, Parbhani Kranti, Sabz Pari and Karishma okra varieties. Both insecticides provided effective control of Jassid and kept the population below economic threshold level up to ten days after insecticidal application. However, Methamidophos 60SL proved better on Pusa Swani as compared to Monocrotophos 40WSC, which decreased jassid population on Parbhani Kranti, Sabz Pari and Karishma, respectively.
