The semidisintegration period of Sayphos over tobacco leaves is determined--2.5 days at angular coefficient of the disintegration straight line K=0.12 1 ppm/ 1 mg/kg concentration of Sayphos over tobacco leaves is considered as harmless and accordingly safe for work. A table for minimal terms of safe work computation is also suggested. Because of the slow Sayphos decomposition in soil, the preparation should be employed but once--after the planting of tobacco.
测定了赛福斯在烟叶上的半分解期——在分解直线的角系数K = 0.12时为2.5天。烟叶上赛福斯浓度为1 ppm/1 mg/kg时被认为是无害的，因此工作时是安全的。还给出了一个安全工作最短期限计算表。由于赛福斯在土壤中分解缓慢，该制剂应仅在烟草种植后使用一次。
