Rimsulfuron {N-[[ 4,6-dimethoxy-2-pyrimidinal)amino ]carbonyl]-3-( ethylsulfonyl)
-2-pyridinesulfonamide} is a new sulfonylurea herbicide under development by E.I.
Dupont de· Nemours & Company Inc. for preemergence and postemergence grass
and broadleaf weed control in Solanaceous vegetable crops. The efficacy and
selectivity of rimsulfuron were determined in potatoes, transplanted tomatoes, and
transplanted peppers in field studies in 1991, 1992, and 1993.
Treatments included rimsulfuron and metribuzin
alone and in combination in
potatoes and tomatoes, rimsulfuron alone in peppers, and sequential applications of
rimsulfuron in tomatoes and peppers. Application timings included preemergence
and postemergence in potatoes, while only post-transplant applications were
evaluated in tomatoes and peppers. Preemergence applications of rimsulfuron
controlled weeds if rainfall was received within a few days following application.
Control was often greater in potatoes and tomatoes than in peppers. These
differences likely relate to more frequent rainfall events in potatoes and tomatoes
than in the later-planted peppers.
