Abstract
The efficacyof three insecticide spray schedules comprising eight insecticides viz. thiomethoxam,diafenthiruan, buprofezin, cypermethrin, fenpropathrin, methamidophos, endosulfan and quinalphos was compared, using recommended doses, against the sucking pest-insect complex of FS-628 cotton. All the insecticidal spray schedules tested, in general, were effective against the sucking pest-insects. On numerical basis, however, an insecticide spray schedule involving thiomethoxam followed by one spray of quinalphos and another with fenpropathrin + buprofezin was found as the most effective both against each individual sucking pest-insect and their overall complex. Key words: cotton, insecticides efficacy, sucking pest-insects
