Glufosinate is a non-selective contact herbicide with some systemic action. Translocation occurs only within leaves, predominantly from the leaf base to the leaf tip. Glufosinate-ammonium is used for control of a wide range of annual and perennial broad-leaved weeds and grasses in fruit orchards, vineyards, rubber and oil palm plantations, ornamental trees and bushes, non-crop land, and pre-emergence in vegetables. Also used as a desiccant in potatoes, sunflowers etc. For control of annual and perennial weeds and gresses in glufosinate-tolerant crops (oilseed rape, maize, soya bean, sugar beet) developed through gene technology. |
