杀虫双是一种有机氮广谱性杀虫剂。它除对害虫具有触杀和胃毒作用外,还具有很强的内吸作用。药剂接触作物后,能很快被作物根、叶吸收和传导,尤以根部吸收能力比叶片吸收大得多。许多报道指出,杀虫双对水稻、蔬菜、柑桔等多种作物上的几十种害虫均有很好的防治效果,持效期为12天左右,如在土壤中深施,则可延长到20～40天。为确定杀虫双对小地老虎的防治效果,为其开发利用提供依据,1987年用杀虫双对春玉米一代小地老虎进行了试验。
Insecticidal double is a broad-spectrum organic nitrogen insecticide. In addition to its pest contact and stomach poisoning effect, but also has a strong systemic action. Pharmacy after contact with crops, can quickly be crop root, leaf absorption and conduction, especially in the root absorption capacity is much larger than the leaf absorption. Many reports pointed out that insecticidal double pairs of rice, vegetables, citrus and other crops on dozens of pests have good control effect, persistence for about 12 days, as in the soil in the deep Shi, you can extend To 20 to 40 days. In order to determine the control effect of insecticidal double pairs of Tigers to provide the basis for its development and utilization, the 1987 trial of insecticidal double-pair spring maize genus Tigers was conducted.
