GENERAL INSTRUCTIONS

APPLICATION Affinity Force Herbicide is an early post-emergence herbicide for the control of certain broadleaf weeds in winter cereals and pyrethrum, and sedge weeds in rice. Affinity Force is a fast-acting contact herbicide that controls weeds through a process of membrane disruption. The foliar uptake of Affinity Force is rapid, and plant desiccation can occur within 1 to 4 days of application. Application of Affinity Force should target small actively growing weeds. Subsequent germinations will not be controlled. Affinity Force should always be tank mixed with MCPA amine in winter cereals.

SYMPTOMS Affinity Force is rapidly absorbed through the foliage of plants. Within a few hours following application, the foliage of susceptible weeds shows signs of desiccation, and in subsequent days necrosis and death of the plant. Due to environmental conditions and certain spray tank additives, some herbicidal symptoms may appear on the crop in the form of leaf spotting. However, the crop recovers quickly, usually within two to three weeks of treatment. Extremes in environmental conditions, e.g., temperature and moisture, soil conditions, and/or cultural practices may affect the activity of Affinity Force.

RICE In rice, when applied to permanent flood water, Affinity Force is rapidly absorbed through the foliage of plants. Within a few days following application, the foliage of susceptible weeds shows signs of necrosis and later death. Herbicidal symptoms may appear on the crop in the form of leaf yellowing on submerged leaves and bronzing on exposed leaves. In most cases, seedlings usually recover rapidly. DO NOT apply Affinity Force to the long grain rice varieties Kyeema and Doongara.

Annual Grass Control Affinity Force should not be mixed with selective grass herbicides, as grass weed control is significantly reduced, and excessive crop injury may occur. Instead, allow a 10-14-day interval between separate broadleaf and grass herbicide applications.

USE OF SURFACTANT/ WETTING AGENTS/ OIL ADJUVANTS DO NOT add wetters, spray oils, or oil/surfactant adjuvants to the tank mix of Affinity Force plus MCPA. The addition of wetters, oils, and oil/surfactant blends will greatly increase crop injury without any significant improvement in weed control.

TIMING Application should be made to small, actively growing weeds generally less than 6 to 8 leaf in stage - refer to growth stages for specific weeds. As Affinity Force is a contact herbicide, best control is achieved when weeds are exposed and are not shielded by other weeds and/or the crop.

MIXING Add half the required volume of water to the spray tank and start agitation. Then add the measured amount of Affinity Force. In cereals, add the required volume of MCPA amine next, then add buffering agent if required, and then the balance of water to the tank. Maintain good agitation at all times until spraying is completed.

APPLICATION Apply Affinity Force (plus MCPA amine in cereals) as a broadcast application. Use conventional boom sprayers with either mechanical or by-pass agitation. Spray equipment should be properly calibrated to ensure correct application. Use a spray volume of 50 to 150 liters per hectare. Experience has shown that using a minimum spray volume of 100 L/ha can improve weed control.

WATER MANAGEMENT It is essential to lock up bays 1 day prior to application and hold water for at least 5 days after application. To optimize weed control and minimize crop injury, ensure there is sufficient water to cover the crop at application.

SPRAYER CLEAN OUT Thoroughly clean all spray equipment using the following procedure when you have finished spraying highly active materials such as carfentrazone-ethyl. In addition to the following procedure, ensure proper equipment clean-out for any other products mixed with Affinity Force as specified on the other product labels.
