ActivityHerbicide
Flumetsulam is active following applications to soil and to foliage. It can be applied prior to planting and pre-emergence in soybeans and pre-emergence to early post-emergence (from 2-4 true leaves in weeds) in maize. Flumetsulam is safe to maize, soybeans and small-grain cereals, but phytotoxic to oilseed rape, cotton and sugar beet. -

Environmental Profile
Ecotoxicology:
Bees: LC50 >100 μg/bee. NOEL 36 μg/bee. Birds:Acute oral LD50 for bobwhite quail >2250 mg/l. Dietary LC50 (8 d) for bobwhite quail and mallard ducks >5620 mg/l.Daphnia:Non-toxic.Fish: LC50 (96 h) for silverside minnow >379 mg/l. Non-toxic to fathead minnow and bluegill sunfish.Other aquatic spp.: LC50 for shrimp >349.
Environmental fate:
Animals:Rapidly cleared via urine and faeces with no metabolites. 5-Hydroxy metabolite found in the hen.Soil:Availability of flumetsulam in soil is principally dependent upon soil pH and organic matter. Herbicidal activity increases as pH increases and organic matter decreases. DT50 in soil (25 °C, Plant: DT50 in maize 2 h, soya beans 18 h, Chenopodium 131 h. Metabolites depend on the species; 5-hydroxy or 5-methoxy derivatives are common. -
