PERFORMANCE OF NOVEL VS TRADITIONAL INSECTICIDES FOR THE CONTROL OF Amrasca biguttula biguttula (HOMOPTERA, CICADELLIDAE) ON COTTON

Amrasca biguttula biguttula (Ishida) can reduce the yield of cotton approximately 25%. No potential predators have been recorded in the field for its control. To overcome this pest insecticides play significant role in the improvement of crop yields all over the world during the last four to five decades. To save the crop from this notorious pest, ten formulations of insecticides viz., acephate 75SP (Acephate) @ 625g, imidacloprid 25WP (Imidacloprid) @188g, thiamethaxim25WG (Actara) @ 60g, imidacloprid 70WG (Confidor) @ 43g, dimethoate 40EC (Sanitox) @ 1000 ml, nytonpyron10SL (Pyramid) @ 500ml, lambdacyhlothrin2.5E (Kango) @ 825 ml, thiachloprid 480SC (Talent) @ 63 ml, imidacloprid 25SL (Confidor) @ 500ml, and diafenthiuron 500SC (Polo), @ 500ml, per hectare were sprayed in the field having maximum population of nymphs and adults of Jassid at Cotton Research Station, Multan on cotton variety Bt- 886 in the month of July, 2011 and 2012. The maximum mortality of jassid was observed in those treatments, where acephate was applied with 79, 72, 65 mortality, nytonpyron with 69, 63, 55 and imidacloprid 68, 63, 57 percent mortality after 24, 72 and 168 h of spray. Minimum mortality of jassid was observed in the treatments where talent was applied having 25, 17 and 16 percent mortality 24, 72 and 168 h after spray. By the application of acephate, pyramid and confidor 25SL on cotton crop the yield can be increased.
