' WATER MANAGEMENT - RICE (Irrigation and Flood Water) Optimum weed control with QUINSTAR@ 4L is highly dependent on proper use of irrigation, including effective flush irrigation to maintain moist soil conditions and timely establishment of permanent flood water.Soil applications and residual activity from foliar applications require moist ' soil conditions for weeds to uptake the herbicide and be controlled.Therefore, keep the soil moist to maintain weed control. If the soil is per- mitted to dry and weeds emerge,flush irrigate the field to reactivate the residual activity of the herbicide while weeds are small(1" or less). If required, make additional QUINSTAR®4L applications as needed, but limit total usage to 16 fluid ounces per acre per season. In water-seeded rice plantings and in pin-point flood culture, drain all water from the rice field and ensure seedling rice has at least two leaves before apply- ing QUiNSTAR®4L. Rice seedlings without 2 leaves may be injured. Flood water levees should be formed prior to applying QUiNSTAR®4L for ' more consistent weed control.Residual weed control on the levee is dependent on moist soil conditions on the levee.If soil on the levee dries, erratic weed control may result. If a heavy rain occurs after applying QUINSTAR8 4L,drain the excess water from the rice field to avoid possible rice injury. APPLICATION INSTRUCTIONS - RICE Whenever possible, spray mixtures should be applied using ground spray equipment. Ensure ground and aircraft spray equipment is properly calibrated and spray coverage is uniform.Always use spray nozzles and other equip- ment designed to reduce accidental spray drift.Always use drift control products and limit spray applications to periods when wind and other weather conditions do not favor spray drift beyond the border of the rice field. Preplant/Pre-emergence and Delayed Pre-emergence: Water Volume:Apply 10-40 gallons of water per broadcast acre. ' Spray Pressure: Use 25-40 psi. Postemergence: Water Volume:Apply 10-20 gallons of water per broadcast acre. ' Spray Pressure: Use 25-40 psi. Air Application: Water Volume:Apply a minimum of 5 gallons of water per acre. Spray Pressure: Use a maximum of 40 psi. Soil Applications: QUINSTAR&4L can be applied to the soil surface before,during,or after planting of dry-seeded rice.When applied to the soil surface and acti- vated by rainfall or irrigation, roots of susceptible grasses and broadleaf weeds uptake the herbicide resulting in commercially acceptable ' control before weed competition reduces rice productivity. Soil texture and clay content determines the proper use rate for optimum weed control,with heavier soil textures and higher clay content requiring higher use rates as directed in Table 1. Foliar Applications: QU1NSTAR@ 4L can be applied to the foliage of susceptible grasses and broadleaf weeds in dry-seeded and water-seeded rice.When applied ' to weed foliage, leaves and stems partially uptake the herbicide. It is essential that rice be flushed after a foliar application to maximize root absorption resulting in commercially acceptable weed control. Additionally, the herbicide reaching the soil surface moves into the soil with rainfall or irrigation providing residual weed control. In general,smaller weeds are more effectively controlled with lower use rates,with larger weeds requiring higher use rates for more complete control.The use rates in Table 1 are directed for foliar applications to provide commer- cially acceptable control of susceptible weeds based on weed size or growth stage. ADDITIVES - RICE For postemergence applications only, adding 2 pints of crop oil concentrate per acre will improve leaf and stem uptake of the herbicide and ' enhance weed control. Drift Control products: Drift control products should always be added to the spray solution to affect spray droplet size and other characteristics,reducing the poten- tial of off-target accidental spray drift. ' TANK MIXING INFORMATION - RICE While QUiNSTAR@ 4L herbicide is effective in controlling a broad spectrum of annual grasses and broadleaf weeds, more effective weed con- trol may be obtained or additional weeds may be controlled by tank mixing QUiNSTAR®4L with other herbicides labeled for weed control in ' rice.The table below describes some weed situations where tank mixing is appropriate. Read and follow all use directions, precautions, and restrictions for each herbicide in the spray mixture.The most restrictive labeling applies to tank mixes. 7
