Abstract
Abstract Compounds of the formula ##STR1## exhibit, in the pre-emergence process and in the post-emergence process, a good herbicidal action against a number of dicotyledonous weeds, they are well tolerated in monocotyledonous crops, such as wheat, barley, rice, sorghum and maize, and are also selectively active in some dicotyledonous crops such as soy beans, groundnuts and the like.
