4-chloro-2-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl) aminocarbonyl]aminosulfonyl]benzoic acid (1-methylethyl) ester and its agriculturally suitable salts are highly active preemergent and postemergent herbicides of particular interest for controlling blackgrass in cereal crops. n The compound may be made by a variety of routes, e.g. by reacting (1-methylethyl)-4-chloro-2-(isocyanatosulfonyl)-benzoate with 4-methoxy-6-methyl-1,3,5-triazin-2-amine. |
