ActivityHerbicide
Butroxydim is absorbed by foliage and is most active when applied to young weeds. The use of adjuvants is recommended to optimise activity. Butroxydim has the potential to damage cereal crops, but no problems have been encountered with cereals grown in rotation with target crops. -
CropUseCropUses:
cotton, soybeans, peanuts, legumes, sunflowers
Application rates vary from 25-75 g ai/ha depending on the target weed, growth stage and environmental conditions.

Environmental ProfileEcotoxicology:
Algae: EbC50 for Selenastrum capricornutum 0.71 mg/l.Bees: LD50 (contact, 24 h) >200mg/bee.Birds:Acute oral LD50 for mallard ducks >2000, bobwhite quail 1221 mg/kg. Sub-acute dietary LC50 (5 d) for mallard ducks >5200, bobwhite quail 5200 mg/kg.Daphnia: LC50 (48 h) >3.7 mg/l.Fish: LC50 (96 h) for rainbow trout >6.9, bluegill sunfish 8.8 mg/l.Worms: LC50 (14 d) for Eisenia foetida >1000 mg/kg.
Environmental fate:
Animals:In rats, following oral administration, >90% of the dose is excreted within 7 d. Various oxidative transformations of the butyryl chain dominate the metabolic pathway. Neither parent nor metabolites bioaccumulate in tissues.Soil:Soil Koc 6-1270 (stronger adsorption in low pH soils). Rapid degradation in aerobic soil, lab. DT50 c. 9 d (20 °C, 40% MHC, pH 7.0, 4.09%
Fish
LC50 6.9 mg/litre
Daphnia
LC50 1.5 mg/litre
Bee [contact]
LD50 >200 μg/bee
Fate in soil:
Butroxydim is degraded rapidly in soil. The half-life is nine days under aerobic conditions.Fate in aquatic systems:
Butroxydim is degraded by hydrolysis and photolysis.
