| Abstract | ||
| Field studies were conducted in El-Beheira Governorate during the growing cotton season of 2013 to investigate the effect of four IGRs compounds (Ageron®, Match®, Dimilin® and Topron®) against the cotton leaf worm, Spodoptera litorallis (Boisd); six pyrethroids; (Icton®, Lamda-Z®, Pulsar®, Buldock®, Sumi-alfa KZ® and Fenerate-S®) in addition to, Dora® as an organophorous compound against the cotton bollworms; Pectinophora gossypiella (Saund.) and spiny bollworm Earias insulana (Boisd.), besides, the side effects of these tested compounds on cotton yield was also studied. Results indicated that Topron® gave higher reduction of the cotton leafworm infestation amounted to 85.7 % followed by Match® (83.5%), then, Ageron® (82.1%). For the cotton bollworm, the higher reduction was recorded with Sumi-alfa KZ® (83.60%) followed by Lamda-Z® (83.2%), while, Buldock® gave a more lower reduction of 80.8%. The evaluated percentages of reduction values for the other evaluated insecticides were 82.6% for Icton®, 82% for Pulsar®, 82.1% for Dora® and 81.1% for Fenerate-S®. All the tested insecticides increased the cotton yield in comparison to the untreated check. | ||
