１４Ｃ苄嘧磺隆与尿素混用，处理后１ｈ，陌上菜〔Ｌｉｎｄｅｒｎｉａｐｒｏｃｕｍｂｅｎｓ（Ｋｒｏｃｋ．）Ｐｈｉｌｃｏｘ〕植株的１４Ｃ放射性计数达到高峰。然而，１４Ｃ苄嘧磺隆单用，陌上菜植株的１４Ｃ放射性计数随时间延长而缓慢增加，直至４８ｈ仍显著低于１ｈ的除草剂与尿素混和的１４Ｃ放射性计数。处理后２４ｈ，１４Ｃ苄嘧磺隆在陌上菜植株中的分配以根系最高，茎次之，叶最低。１４Ｃ苄嘧磺隆＋尿素浸根，促进陌上菜植株对除草剂的吸收，但涂抹叶片时，无论单用还是混用，陌上菜植株均不吸收除草剂。
14C-Bensulfuron-methyl was mixed with urea. After 1 h of treatment, the 14C radioactive counts of Lindernia officinalis (Krock.) Philcox plants peaked. However, the 14C radioactive counts of 14C-Bensulfuron-methyl alone and the vegetables on the street increased slowly with time and remained significantly lower than the 14C radioactivity count of the mixed herbicide and urea until 48h. 24h after treatment, 14C bensulfuron - methyl plants in the distribution of vegetables in the highest root, stem next, leaves the lowest. 14 C Bensulfuron-methyl + urea immersed roots, to promote the absorption of herbicides on the plants on the street, but smear leaves, no matter single or mixed, the plants on the street do not absorb the herbicide.
