Crops: Maize, Wheat, etc.

Weeds: Annual broad-leaved weeds

Mode of action: Fluroxypyr is applied as an ester, such 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.
