敌敌畏、磷化铝混合自然潮解环流熏蒸杀虫技术探索

Technologic exploration of natural deliquescence and recirculation fumigation of dichlorvos mixed with aluminium phosphide

介绍了敌敌畏与磷化铝混合粮面施药、自然潮解环流熏蒸试验。研究表明,敌敌畏与磷化铝混合环流熏蒸几乎对所有储粮害虫均有较好的熏杀效果,尤其是对书虱、螨类、谷蠹等抗药性害虫熏杀效果更为明显,与仓外投药环流熏蒸相比,大大降低了熏蒸费用,缩短了投药时间。

The experiment of recirculation fumigation and natural deliquescence of dichlorvos and aluminium phosphide mixed with grain powder is introduced. The results show that the measure can kill almost all the store-grain insects, especially for troctes, divinatorius, mulls which have the characteristic of pesticide resistance. Compared with the technology of recirculation fumigation by drugging out of the warehouse, it can greatly reduce the costs and time for drugging.
