Maximum Yearly Limits
DO NOT apply more than 128 fluid ounces of QUINCLORAC 1.5 L herbicide per acre (or 2.9 flozs per 1000 sq ft) in one year (1.5 lbs ae per acre per year).
Mowing Instructions
DO NOT mow 2 days before or after applying QUINCLORAC 1.5 L to maximize weed control and minimize potential turf injury. Clippings from the first three mowings afterapplication should be left on the treated area.
Effective Temperature Range
For best results, weeds should not be under stress from lack of water, excessive water, low fertility,mowing shock, excessive hot or cold temperatures, or injury from other herbicide applications.
Water Instructions
If soil moisture is not sufficient prior to QUINCLORAC 1.5 L application,irrigation may improve weed control. For best results, DO NOT water or irrigate for 24 hours afterapplication. If rainfall does not occur in 2 to 7 days after application, irrigation of at least 1/2 inch isdesirable.
Before Seeding Instructions
The use of QUINCLORAC 1.5 L before or after seeding or overseeding a turf area will not significantly interfere with the turf grass seed germination and growth ofthose grass types identified as tolerant or moderately tolerant in Table 1. Consult Table 4 for timingof applications concerning any seeding, overseeding or sprigging situation.
Surfactant Instructions
Methylated seed oil is the preferred adjuvant for postemergence applications. However, if an MSO is not available in your region, the use of a crop oilconcentrate or other high quality surfactant must be used in the spray tank at the time of application. (Refer to actual product label for use rates and directions.)

Instructions:
Under certain conditions, application of QUINCLORAC 1.5 L made to annual grasses at 2 to 4 tiller may not provide complete control. A sequential application will be required for grass control in these situations. Optimum control is achieved when applications of QUINCLORAC 1.5 L + methylated seed oil are applied either before second tiller or as weed grasses mature.

Optimum control is achieved when applications of QUINCLORAC 1.5 L + methylated seed oil are applied either before second tiller or as weed grasses mature. Biotypes of large and smooth crabgrass in California have shown varied response to QUINCLORAC 1.5 L. If control failure occurs following a full or split application, DO NOT reapply QUINCLORAC 1.5 L. Change to a herbicide with a different mode of action.
