在储存2028 t优质中籼稻的房式仓,采用20 g/m3的硫酰氟环流24 h、熏蒸5 d的试验表明硫酰氟熏蒸对玉米象、米象、谷蠹、赤拟谷盗、书虱等5种7个品系储粮害虫具有很好的杀灭效果和抑制作用,并且反映硫酰氟熏蒸对磷化氢抗性害虫和敏感害虫没有明显的不同效果;同时通过定点和综合样的稻谷品质分析发现,硫酰氟熏蒸对稻谷品质没有表现出负面影响。通过对2个点不同层面稻谷中残留分析,各个点的残留都不超标,都符合GB 2762-2005的要求。
In the storage of 2028 t high-quality mid-indica rice warehouse, using 20 g / m3 sulfuryl fluoride circulating for 24 h, fumigation 5 d test showed that sulfuryl fluoride fumigation on corn, rice, valley beetle, Ticks and other five kinds of seven kinds of stored grain pests have good killing effect and inhibition, and reflect the sulfuryl fluoride fumigation of phosphine resistant pests and sensitive pests no significant difference; at the same time by the fixed point and comprehensive sample Analysis of rice quality found that sulfuryl fluoride fumigation did not show any negative impact on rice quality. Through the analysis of residue in paddy at two different levels, the residues at each point are not exceeded, all of which meet the requirements of GB 2762-2005.
