南开大学元素有机化学研究所研制的复肥农药新品种──12％久·高氯乳油，不仅对棉铃虫有良好的防治效果，而且通过对防治苹果树蚜虫、梨二叉蚜试验，其效果明显优于各对照药剂的防效，同时经试验确认从保证药效，节约成本，减少污染和延缓害虫产生抗药性考虑，防治苹果蚜虫以浓度6×10－5～12×10-5为宜，防治梨二叉蚜以浓度9×10-5～12×10－5为宜，并且该药在试验期间未出现药害，对作物安全，残效期可达7天。
Nankai University Institute of Elemental Organic Chemistry, developed a new compound fertilizer - 12% long-high chlorine EC, not only has a good control effect on cotton bollworm, but also through the prevention and control of apple aphids, pears pear aphid test results Obviously better than the control efficacy of the control agent, and confirmed by the test to ensure efficacy, cost savings, reduce pollution and delay the emergence of drug resistance insects, apple aphids to control the concentration of 6 × 10-5 ~ 12 × 10-5 is appropriate , The control pear Aphis gossypii at a concentration of 9 × 10-5 ~ 12 × 10-5 is appropriate, and the drug did not appear during the test phytotoxicity, crop safety, residual effect of up to 7 days.
