用高效顺反氯氰菊酯、辛硫磷、久效磷、灭多威、甲基对硫磷及水胺硫磷等为有效成份，添加一定量的增效剂、渗透剂及溶剂等，配制成杀虫液剂。以３龄棉铃虫为实验幼虫，经过上百种配方的几百次实验，筛选出由有效成份高效氯氰菊酯、辛硫磷、甲基１６０５配成的复配杀虫液剂护棉灵，共毒系数为４６４．６，增效倍数为３．６倍。通过大田验证，４０％护棉铃复配制剂，在棉田的药效明显优于对比单剂，也优于复配药剂３０％灭铃灵，且防治费用低。
Cypermethrin, phoxim, monocrotophos, methomyl, methyl parathion and isocarbophos and other effective ingredients, add a certain amount of synergist, penetrant and solvent, formulated to kill Insect liquid. With 3-day-old cotton bollworm as experimental larvae, hundreds of experiments with hundreds of formulations were conducted to screen the compound insecticide solution containing cottonseed, cypermethrin, phoxim and methyl 1605 The coefficient is 464.6, the multiplier is 3.6 times. Field validation, 40% bollworm compound formulations, the efficacy of the cotton field was significantly better than the single agent, but also better than the compounding agent 30% Ling Ling Ling, and prevention and control costs low.
