| 摘 要： | ２５％对氯杀虫酯乳油（以下简称Ｐａｃｙ）系采用对硫磷与氯氰菊酯经科学复配而成的混剂，经室内毒力测定，该混剂对棉蚜具有明显的增效作用，其共毒系数为４０４．８。田间试验结果进一步表明，该混剂最佳配方为：对硫磷：氯氰菊酯＝２４７∶３，使用该配方制成的２５％混剂防治稻棉主要害虫，每６６７ｍ２用量１００～１５０ｇ，防效达９０％以上，持效期１０～１５ｄ。１９９６年示范推广４．７万ｋｍ２，经济效益显著

Control Effect of Pacy Against Principal Pests on Rice and Cotton |
| |
| Abstract: | Pacy is a mixture of parathion and cypermethrin. It had synergical effect with a co-toxicity coefficient of 404.8 by indoors determination of LC 50 . The results of field trial indicated that the best proportion of pacy was composed of 24.7% parathion and 0.3% cypermethrin. At the rate of 375～562.5 g/km 2, the control effect was over 90% and could last 10～15 days. In 1996 the area of field experiment was 47000 km 2 and the economic benefit was great. |
