Storage and Disposal (Cont.) Triple rinse or pressure rinse container (or equivalent) promptly after emptying. Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank and drain for 10 seconds after the flow begins to drip. Fill the container 1/4 full with water and recap. Shake for 10 seconds. Pour rinsate into application equipment or a mix tank or store rinsate for later use or disposal. Drain for 10 seconds after the flow begins to drip. Repeat this procedure two more times. Pressure rinse as follows: Empty the remaining contents into application equipment or a mix tank and continue to drain for 10 seconds after the flow begins to drip. Hold container upside down over application equipment or mix tank or collect rinsate for later use or disposal. Insert pressure rinsing nozzle in the side of the container, and rinse at about 40 psi for at least 30 seconds. Drain for 10 seconds after the flow begins to drip. Refillable containers 5 gallons or larger: Container Reuse: Refillable container. Refill this container with pesticide only. Do not reuse this container for any other purpose. Cleaning the container before final disposal is the responsibility of the person disposing of the container. Cleaning before refilling is the responsibility of the refiller. To clean the container before final disposal, empty the remaining contents from this container into application equipment or a mix tank. Fill the container about 10% full with water and, if possible, spray all sides while adding water. If practical, agitate vigorously or recirculate water with the pump for two minutes. Pour or pump rinsate into application equipment or rinsate collection system. Repeat this rinsing procedure two more times. Nonrefillable containers 5 gallons or larger: Container Reuse: Nonrefillable container. Do not reuse or refill this container. Offer for recycling if available. Triple rinse or pressure rinse container (or equivalent) promptly after emptying. Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank. Fill the container 1/4 full with water. Replace and tighten closures. Tip container on its side and roll it back and forth, ensuring at least one complete revolution, for 30 seconds. Stand the container on its end and tip it back and forth several times. Turn the container over onto its other end and tip it back and forth several times. Empty the rinsate into application equipment or a mix tank or store rinsate for later use or disposal. Repeat this procedure two more times. Pressure rinse as follows: Empty the remaining contents into application equipment or a mix tank and continue to drain for 10 seconds after the flow begins to drip. Hold container upside down over application equipment or mix tank or collect rinsate for later use or disposal. Insert pressure rinsing nozzle in the side of the container, and rinse at about 40 psi for at least 30 seconds. Drain for 10 seconds after the flow begins to drip. General Information Clincher®^ SF herbicide is a postemergence herbicide for selective control of grass weeds in drilled and water seeded rice. A spray volume of 10 gallons or more per acre (gpa) and uniform coverage are required for optimum performance. Clincher SF is rainfast within 2 hours after application and has no preemergence or soil residual activity. Only actively growing grass weeds emerged at the time of application are controlled. Clincher SF will not control broadleaf weeds or sedges. The product may also be applied for control of susceptible grass weeds in ratoon rice up to 60 days before harvest. General Use Precautions and Restrictions
For extremely heavy grass densities, a sequential application program of Clincher SF can be made at 15 fl oz per acre 7 to 10 days after permanent flood, followed by a second application of Clincher SF at the rate of 10 fl oz per acre between 10 and 14 days later. If Clincher SF is applied as a postflood salvage treatment to previously untreated areas, to fields with previous failed herbicide applications, or areas of extremely high grass weed density, total control of labeled grass weeds should not be expected. Regrowth of these grass weeds may occur. Water Seeded Rice Before permanent flood: Allow grass weeds to germinate before application. Good soil moisture conditions (saturated soil) and actively growing grass weeds are essential. Residual water remaining in the field does not adversely affect grass weed control so long as grass weeds are at least 70% exposed. Ground application of Clincher SF is not recommended as weed control may be reduced. If fields are drained at application, they should be re-flooded beginning 2 hours after application and within 24 to 48 hours after application to prevent germination of new grass weeds. After permanent flood (postflood): Maintain the flood at application so long as grass weeds are at least 70% exposed. Following application, it is important to maintain a flood of 2 to 4 inches across the field to reduce the risk of grass weed regrowth. A permanent flood following application provides the best results. For extremely heavy grass densities, a sequential application program of Clincher SF can be made at 15 fl oz per acre 7 to 10 days after permanent flood, followed by a second application of Clincher SF at the rate of 10 fl oz per acre between 10 and 14 days later. If Clincher SF is applied as a postflood salvage treatment to previously untreated areas, to fields with previous failed herbicide applications or areas of extremely high grass weed density, total control of labeled grass weeds should not be expected. Regrowth of these grass weeds may occur.
