Abstract

Herbicides 3-(p-chlorophenyl)-1,1-dimethylurea (monuron); 2-chloro-4-ethylamino-6-isopropylamino-s-triazine (atrazine); 2-chloro-4,6-bis(ethylamino)-s-triazine (simazine); 2-methoxy-4,6-bis(isopropylamino-s-triazine (prometone); 2-chloro-4,6-bis(isopropylamino)-s-triazine (propazine); and 2,4-bis(isopropylamino)-6-methylmercapto-s-triazine (prometryne) were studied in four soils. The behavior of monuron, propazine, atrazine, and simazine was similar in each soil, while prometryne and prometone exhibited greater interactions with the soils. Phytotoxicity and movement of the herbicides in soil were inversely related to extent of adsorption.
