For non-residual control of broadleaf and grass weeds in orchards and non-agricultural areas.

GENERAL INSTRUCTIONS

4Farmers Glufosinate-Ammonium 200 is a non-volatile herbicide with activity against many annual and perennial broadleaf weeds and grasses. 4Farmers Glufosinate-Ammonium 200 is absorbed by plant foliage and green stems. 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. 4Farmers Glufosinate-Ammonium 200 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.

Mixing

4Farmers Glufosinate-Ammonium 200 mixes easily with water. Clean water should always be used for mixing with 4Farmers Glufosinate-Ammonium 200. Ensure that the spray tank is free of any residues of previous spray materials. Two-thirds fill the spray tank with clean water, and with agitator operating add the required amount of 4Farmers Glufosinate-Ammonium 200. Add other relevant compatible products. Top the tank up to the required volume with clean water with agitator running.

Application

A. Orchards, plantations, vineyards and other row crops and B. Commercial, industrial, non-agricultural areas, fencelines in agricultural areas and forestry plantations Apply by ground spraying equipment only. Aim to apply a thorough and even coverage of spray to the target plant. Dense stands of weeds should be thoroughly wetted with spray. Incomplete coverage may result in poor control. Equipment set-up should be such that adequate coverage, penetration and volume of spray liquid can be achieved while the potential for off-target movement is minimised.

Boom, Shielded/Hooded or Directed Sprayer Equipment

4Farmers Glufosinate-Ammonium 200 should be applied at label rates (refer to specific column in the list of weeds controlled) in sufficient water to give thorough coverage of weeds. It has been found that 300 to 500 L/ha has given good results under most weed conditions. Special care must be taken when using sprayer/slasher combination units not to cause dust and turbulence, which can carry spray into non-target areas. Directed spraying equipment should be set up in such a way that practically no spray intercepts susceptible parts of the crop being sprayed, but provides good coverage of weeds.

Knapsack and Handgun Equipment

4Farmers Glufosinate-Ammonium 200 should be applied at label rates (refer to specific columns in the list of weeds controlled) in adequate water to thoroughly wet the weeds being sprayed, i.e. 500 to 1000 L/ha. Dense stands will require up to 1000 L/ha of spray mixture, whereas less dense stands will require less water. High volume application using hollow-cone nozzles for hand spraying is recommended.

Controlled Droplet Application (CDA) Equipment

4Farmers Glufosinate-Ammonium 200 may be applied through CDA row spraying equipment fitted with a solid (impermeable) shroud or skirt, at rates as recommended for boom or directed sprayers (refer to specific column in the list of weeds controlled), provided thorough spray coverage of weeds can be achieved. Apply preferably when weeds are less than 15 cm in height, with the equipment set up so that the spray dome only just touches the tops of the weeds. A total spray volume of 20 to 30 L/ha has been found to give good results. Do not mix residual herbicides or any spray adjuvants with 4Farmers Glufosinate-Ammonium 200 when using CDA equipment.
