Common Name Fluroxypyr-methyl heptyl ester
Chemical Name [(4-amino-3,5-dichloro-6-fluoro-2-pyridinyl)oxy]acetic acid methyl heptyl ester
CAS Number 69377-81-7 (acid); 81406-37-3 (ester)
Molecular formula C15H21Cl2FN2O3
ACTION 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.

Description Appearance: White powde with the smell of soap. .
Melting Point: 232-233°C.
Vapour Pressure: 0.125m Pa at 20°C
Stability: Solubility in water 91 mg/L, 45, in acetone 41.6g/L, in Chloroform and dichloromethane > 50g/l.
Specification Fluroxypyr-methyl 95%Tech, 20%EC
Usage 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.
Package 25Kg/drum or packed as required.
