Use

Flupyrsulfuron‐methyl‐sodium (DPX‐KE459) is a post‐emergent cereal herbicide designed for the control of problem grass weeds, such as Alopecurus myosuroides and Apera spica‐venti, as well as a wide range of broadleaf weeds. The application rates are 810 g a.i. ha1. It is commercialized by DuPont under the trade name Lexus 50DF as a stand‐alone product or as Lexus Class in a 1 : 2 ratio in combination with carfentrazone‐ethyl and was launched in 1997. At the 10 g a.i. ha1 rate, the following broadleaf weeds are well controlled: Chenopodium album, Lamium purpureum, Matricaria spp., Polygonum aviculare, Polygonum convolvulus, Senecio vulgaris, and Sinapis arvensis. Ciral is a combination of flupyrsulfuron‐methyl‐sodium (33.3%) and metsulfuron‐methyl (16.7%) used for the control of A. myosuroides, A. spica‐venti, Poa annua, and also annual broadleaf weeds (except Galium aparine) such as Thlaspi arvense, Capsella bursa‐pastoris, Galeopsis spp., Matricaria spp., Papaver rhoeas, Centaurea cyanus, Brassica napus, Viola arvensis, Lamium spp., Myosotis arvensis, and Stellaria media. Ciral is a flexible product that can be applied in autumn and spring in wheat and in flax at a dose rate of 25 g ha1 [30] of formulated product containing 8 g a.i. flupyrsulfuron‐methyl‐sodium.Flupyrsulfuron‐methyl‐sodium (DPX‐KE459) is a post‐emergent cereal herbicide designed for the control of problem grass weeds, such as Alopecurus myosuroides and Apera spica‐venti, as well as a wide range of broadleaf weeds.
