Non-selective & Contact Herbicide With Some Systemic Action
Glufosinate ammonium is a member of the phosphonicacid group of herbicides. It is a non-volatile herbicide with non-selective activity against many annual and perennial broadleaf weeds and grasses. Glufosinate ammonium is absorbed by plant foliage and green stems. It is an inhibitor of glutamine synthetase. It is not significantly translocated as an active herbicide throughout the plant, and therefore will only kill that part of a green plant that is contacted by spray. Glufosinate ammonium does not provide residual weed control. Visible symptoms of control appear in 3 to 7 days, but complete desiccation may take 20 to 30 days under cool conditions. Best results are achieved when application is made under good growing conditions. Application to weeds under stress (e.g. due to continuous severe frosts, dry or waterlogged conditions) should be avoided.
