加拿大农业研究所等对杀螟硫磷用作粮食防护剂的特性进行了研究,并将实验结果与Abdel一Kader等在1980年对马拉硫磷的试验结果进行了对照。比较表明在低温(一35,一2℃)下贮藏,两者在小麦上的残留娜受有明显的区别。随着温度的升高,杀螟硫磷一直比马拉硫磷更能保持长效性,这种趋势‘在较低温度下更为明显。经72周的贮藏后,原始剂量的杀螟硫磷在一5、5、10℃分别散失了18%、35%、56%,相应地马拉硫的散失分别为26%、41%、74%。
Canadian Agricultural Research Institute and other properties of fenitrothion for food protective agent were studied and the experimental results and Abdel-Kader et al in 1980 on the test results of malathion were compared. Comparison shows that the low temperature (a 35, a 2 ℃) storage, both on the residual Na Na by the significant difference. As the temperature increases, fenitroth has been more durable than malathion long-term, this trend ’at lower temperatures even more pronounced. After 72 weeks of storage, the initial dose of fenitrothion was lost by 18%, 35% and 56% at a 5,5 and 10 ° C, respectively, corresponding to 26%, 41% and 74%, respectively %.
