Mowing Instructions
Do not mow 2 days before or after applying Quali-Pro Quinclorac 75 DF.
Effective Temperature Range
To prevent leaf burn and turfgrass damage, do not apply Quali-Pro Quinclorac 75 DF when relative humidity and temperatures are high.
Water Instructions
If soil is dry before a Quali-Pro Quinclorac 75 DF application, irrigation of the turfgrass may improve weed control. For best results, DO NOT water or irrigate for 24 hours after a Quali-Pro Quinclorac 75 DF application. Irrigate the treated turfgrass with at least ½ inch of water 2 to 7 days after application if no rainfall is received within that period.
Before Seeding Instructions
Quali-Pro Quinclorac 75 DF will not significantly interfere with turfgrass seed germination and growth of those grass types identified as tolerant or moderately tolerant in the WEEDS CONTROLLED table if applied before or after seeding or overseeding a turf area.
