MAMMALIAN TOXICOLOGY
Acute toxicity: 1) Acute oral LD50 for rat: R300 a.i.mg/kg. 2) Acute dermal LD50 for rat: >2000 a.i.mg/kg. 3) Inhalation LC50 (4 h) for rat: no data available. 4) Non-irritating to skin (rabbits). 5) Slightly-irritating to eyes (rabbits). 6) skin sensitization: no data available.
NOEL: (2 y) for rats is 0.065 mg/kg b.w. daily; no increase in hepatotoxicity.
ADI: 0.00065 mg/kg b.w./day[Rat, SF=100]
Classification:
Toxicity class WHO (a.i.): II (Moderately hazardous)
EC Risk Classification: Xn - Harmful: R22; N - Dangerous for the environment: R50, R53
ECOTOXICOLOGY
Effect on birds: moderate toxicity to birds, acute LD50 is 1159 a.i.mg/kg. Effect on fish: high toxicity to fish, acute 96 hour LC50 for Bluegill sunfish is 0.088 a.i.mg/L. Effect on aquatic invertebrates: moderate toxicity to aquatic invertebrates, acute 48 hour EC50 for Daphnia magna is 12.3 a.i.mg/L. Effect on algae: moderate toxicity to algae, acute 72 hour EC50 for Navicula pelliculosa is 1.72 a.i.mg/L. Effect on honeybees: low toxicity to honeybees, contact acute 48 hour LD50 is >100 a.i.g/bee, oral acute 48 hour LD50 is >100 a.i.g/bee. Effect on earthworms: moderate toxicity to earthworms, acute 14 day LC50 for Eisenia foetida is >672 a.i.mg/kg.
ENVIRONMENTAL FATE
Animals: In mammals, rapidly converted to the parent acid and eliminated.
Plants: Hydrolysed to haloxyfop, terminal residue haloxyfop, or conjugates. Soil/Environment DT50 <24 h, forming the parent acid, which is then microbially degraded. Haloxyfop acid degradation approximates to first order kinetics and involves degradation to the pyridinol and other minor metabolites. DT50 is 9 to 20.5 d, average 14 d (various soil types).
Usage: The methyl ester reported by Bayer S.A. (M. C. Botte et al., Proc. 15th Columa Conf., 1992, 1, 397) and introduced by DowElanco (now Dow AgroSciences). Manufacturers: Dow AgroSciences. Fatty acid synthesis inhibitor, by inhibition of acetyl CoA carboxylase (ACCase).
Application: Haloxyfop-R-methyl is a selective herbicide, absorbed by the foliage and roots, and hydrolysed to haloxyfop-R, which is translocated to meristematic tissues, and inhibits their growth. Haloxyfop-R-methyl is used post-emergence for control of annual and perennial grasses in sugar beet, fodder beet, oilseed rape, potatoes, leaf vegetables, onions, flax, sunflowers, soya beans, vines, strawberries, and other crops. Applied at 52-104 g a.e./ha.
