摘要
采用55%甲基嘧啶磷乳油与超纯水按1∶2的比例混匀,再对高大平房仓的粮面及上部空间用超低容量喷雾器进行人工仓内喷雾,于2019年4月底和2019年7月底共实施两次人工喷雾施药,以期在粮堆表层形成持续的害虫防护层,在仓温和粮温相对较高时防止仓内粮食受到内外部虫害的感染,同时结合仓内空调控温,将仓内粮食的温度控制在25℃以内,增强甲基嘧啶磷防护层对害虫的持续防治效果。以甲基嘧啶磷作为储粮害虫防护剂能有效地降低磷化铝熏蒸频次,延长磷化铝熏蒸持效期,减少粮库保管员劳动强度,且因其对人毒性低、药剂残留量少,具有经济成本低和对仓房及周边环境无污染等优点,因此以甲基嘧啶磷联合空调控温作为害虫防治新技术,将达到全年整仓免熏蒸的效果。
55% pirimiphos-methyl EC mixed ultrapure water by proportion of 1∶2, was sprayed to the surface and the upper space of grain in large warehouse by Ultra-low-volume sprayer. Our study was performed twice at the end of April 2019 and the end of July 2019 respectively. Stored-grain pest protection layer was formed on the surface of grain bulk to continuously prevent the grain from suffering pest infringement. At the same time, the temperature controlled by air conditioner of warehouse was lower than 25 ℃. In this way, we can maximize the effect of pirimiphos-methyl protective layer on insect pests. By using pirimiphos-methyl will significantly reduce the amount of aluminium phosphide used in large warehouse and the intensity of labor. Because of the low toxicity, residue, cost and environmental friendly of pirimiphos-methyl, we concentrate on replacing aluminium phosphide with pirimiphos-methyl to achieve the goal of warehouse fumigation-free all year round.
