APPLICATION
Formulation types: EC; GR.
Biochemistry: Protoporphyrinogen oxidase inhibitor.
Mode of action: Selective contact herbicide, absorbed more readily by the foliage (and especially the shoots) than by the roots, with very little translocation.
Uses: Control of annual broad-leaved weeds and grasses in a variety of tropical and subtropical crops, by pre- or post-emergence application at rates in the range 0.25-2.0 kg a. I. /ha. Particular crops include tree fruit (including citrus), vines, nuts, cereals, maize, soya beans, peanuts, rice, cotton, bananas, peppermint, onions, garlic, ornamental trees and shrubs, and conifer seedbeds.
Phytotoxicity: Soya beans and cotton may be injured by contact with oxyfiuorfen.
