摘要
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。
20g/m^3 sulfuryl fluoride had been fumigated for 5 days in horizontal warehouse stored 2028t high quality long-grain non-glutinous paddy, recirculated 24 hours by recirculation blower in this period. The research showed that sulfuryl fluoride fumigating was effective on 7 strains the adult pests and F1 progeny of Sitophilus oryzae （L.）, Sitophilus zeamais （Motschulsky）, susceptible and resistant Rh yzopertha dominica Fabricius on phosphine, susceptible and resistant Triboliurn castaneum （Herbst） on phosphine and Liposcelis, and also susceptible and resistant pests to phosphine have no difference in effect by sulfuryl fluoride fumigating. Influences of SF fumigation on paddy quality have no negative effects by measuring the samples on fixed and mixed points in this warehouse. Differ layers paddy samples of this two points were analyzed, the residues of fluoride were lower the MLs ordained by GB 2762-2005.
