导言二氧化碳为储粮过程中积累产生的一种正常气体成份,已经知道:它能影响害虫的呼吸以及提高某些熏蒸剂如二硫化碳、氯化苦、二氯乙烯、环氧乙烷、溴甲烷、氯代甲酸甲酯和甲酸甲酯等的杀虫效果。在杀虫剂使用的潜力发挥方面,目的为了使残留量降低到最小限度,并使之仍然达到经济有效的防治效果,当前提高二氧化碳对磷化氢的熏蒸毒效,具有重要的作用和广泛的意义。 Introduction Carbon dioxide (CO 2), a normal gaseous component accumulated during grain storage, is known to affect pest respiration and enhance certain fumigants such as carbon disulfide, chloropicrin, vinylidene chloride, ethylene oxide, methyl bromide, chlorine Methyl formate and methyl formate insecticidal effect. In terms of the potential for the use of pesticides, the aim is to reduce the residue to a minimum and to achieve cost-effective control and prevention. The current enhancement of carbon dioxide to fumigation of phosphine has an important role and broad significance.
