Water Instructions
Irrigation and Rainfall: If soil moisture is not sufficient prior to QUIN KILL MAX application, irrigation may improve weed control.
For best results, DO NOT water or irrigate for 24 hours after application. If rainfall does not occur in 2 to 7 days after application,
irrigation of at least 1/2 inch is desirable.
After Seeding Instructions
DO NOT apply within 4 weeks after seedling emergence of Kentucky bluegrass, creeping bentgrass, fine fescue blends and
perennial ryegrass. DO NOT apply QUIN KILL MAX prior to and within 2 weeks after seeding seashore paspalum.

Instructions:
Under certain conditions, application of QUIN KILL MAX 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 QUIN KILL MAX + methylated seed oil are applied either before second tiller or as weed grasses mature.
