Fluroxypyr-meptyl 96% TC

Fluroxypyr is a post-seedling herbicide of endosuction conduction, which is quickly absorbed by plants, causing the sensitive plants to appear typical hormone herbicide reaction, plant deformity, distortion, and eventually dying.

Applicable to wheat, barley, corn, grape, orchard, pasture, woodland, lawn, and other places to control broad-leaved weeds, grass weeds ineffective. It is easy to degrade in soil and has a short half-life. It will not cause drug harm to later crops.

Detailed information:

  • Common name: Fluroxypyr-meptyl
  • IUPAC name: octan-2-yl 2-(4-amino-3,5-dichloro-6-fluoropyridin-2-yl)oxyacetate
  • CAS No.: 81406-37-3
  • Molecular formula: C15H21Cl2FN2O3
  • Molecular weight: 367.2
  • State: Solid
  • Packing: 25kg (providing additional packing as required)
  • Mode of action: 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.


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.
