ECOTOXICOLOGY

Effect on birds: moderate toxicity to birds, acute LD50 is  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.

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., , 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.  

Haloxyfop-R-methyl (haloxyfop) can efficiently control Spartina alterniflora in coastal ecosystems, but its effect on soil microbial communities is not known. In the present study, the impact of the haloxyfop on rhizosphere soil bacterial communities of S. alterniflora over the dissipation process of the herbicide has been studied in a coastal wetland. The response of the bacterial community in the rhizoplane (iron plaque) of S. alterniflora subjected to haloxyfop treatment was also investigated. Results showed that the persistence of haloxyfop in the rhizosphere soil followed an exponential decay with a half-life of 2.6-4.9 days, and almost all of the haloxyfop dissipated on Day 30. The diversity of rhizosphere soil bacteria was decreased at the early stages (Days 1, 3 & 7) and recovered at late stages (Days 15 & 30) of the haloxyfop treatment. Application of haloxyfop treatment increased the relative abundance of the genera Pseudomonas, Acinetobacter, Pontibacter, Shewanella and Aeromonas. Strains isolated from these genera can degrade herbicides efficiently, which possibly played a role in the degradation of haloxyfop. The rhizoplane bacterial diversity was reduced on Day 15 while being vastly enhanced on Day 30. Soil variables, including the electric conductivity, redox potential, and soil moisture, along with the soil haloxyfop residue, jointly shape the bacterial community in rhizosphere soil.
