Formulation | EC |
Application/Uses | Fluroxypyr is applied as fluroxypyr-meptyl. After predominantly foliar uptake, the ester is hydrolysed to the parent acid, which is the herbicidally active form, and translocated rapidly to other parts of the plants. Acts by inducing characteristic auxin-type responses, e.g. leaf curling. Uses Fluroxypyr is effective by post-emergence foliar application, controlling a range of economically important broad-leaved weeds (including Galium aparine and Kochia spp.) in all small grain crops, and Rumex spp. and Urtica dioica in pastures. Directed applications are used against herbaceous and woody broad-leaved weeds in orchards (apple only) and plantation crops (rubber and oilpalm), and broad-leaved brush spp. in conifer forests. Post-emergence, broadcast applications of fluroxypyr in maize up to the 6-leaf stage of the crop are used for control of Calystegia sepium, Convolvulus arvensis and Solanum nigrum. The meptyl and 2-butoxy-1-methylethyl esters have similar activity, the advantage of the latter being the wider range of formulation options that are available. Applied at 180-400 g a.e./ha. Phytotoxicity Non-phytotoxic to the crops for which its use is recommended. |
ECOTOXICOLOGY | Animals In rats, following oral administration, fluroxypyr is not metabolised, but is rapidly excreted unchanged, principally in the urine. Plants In plants, fluroxypyr is not metabolised, but biotransformation to conjugates occurs. Soil/Environment In soil, fluroxypyr is rapidly degraded by micro-organisms in aerobic conditions to 4-amino-3,5-dichloro-6-fluoropyridin-2-ol, 4-amino-3,5-dichloro-6-fluoro-2-methoxypyridine, and CO2. DT50 in laboratory soil studies 5-9 d (c. 23 ). Lysimeter and field studies demonstrate there is no evidence of any significant leaching; see M. Snel et al., 15th COLUMA Conf., 1992, 1, 125. |
