Mowing Instructions
Turfgrass injury can be minimized by using one of the following options:
Mow 4 hours after the application of Quali-Pro® T-Nex® or Mow 1 hour before application of Quali-Pro® T-Nex®
Effective Temperature Range
Apply Quali-Pro® T-Nex® to actively growing turf. Use the lower rate of Quali-Pro® T-Nex® in situations when turf is going dormant due to high or low temperatures, or to lack of moisture
Surfactant Instructions
Use surfactants approved for application to turf. Check surfactant label before use
Before Seeding Instructions
Poa Annua Conversion / Renovation
When overseeding or renovating existing turf infested with strands of Poa annua, Quali-Pro® T-Nex® use allows better germination and seedling growth of the more desirable turf, results in fewer clippings, and thus reduces maintenance traffic on new seedlings. Quali-Pro® T-Nex® is foliarly-absorbed; therefore, it does not affect seed germination. Quali-Pro® T-Nex® should be applied 1 to 5 days before seeding and before verticutting, scalping, spiking, or other similar operations.
Temporary initial discoloration of turfgrass infested with Poa annua is possible with aggressive application rates of Quali-Pro® T-Nex®. In the subsequent spring season, apply Quali-Pro® T-Nex® at the higher rate for the turf type and setting listed in the APPLICATION RATE TABLE. As described above, the success of this treatment will also depend on other factors such as growing conditions, fertilization, rainfall, and other agronomic and environmental conditions. 

Bermudagrass Overseeding
In addition to normal turfgrass cultural practices, Quali-Pro® T-Nex® applications to Bermudagrass enhance the establishment of cool-season turfgrasses and help ensure new seedling vigor and growth, will result in fewer clippings, and less maintenance traffic on new seedlings. Since Quali-Pro® T-Nex® is foliarly absorbed, germination and seedling growth is unaffected by Quali-Pro® T-Nex®. 
Apply Quali-Pro® T-Nex® 1 to 5 days before seeding and before verticutting, scalping, spiking, or other similar operations to the bermudagrass.
Aggressive application rates of Quali-Pro® T-Nex® may cause temporary initial discoloration of turfgrass. To avoid discoloration, use the normal seeding rates for your area and turf setting (lawn, fairway, etc.). The success of overseeding will depend on a number of factors including growing conditions, fertilization, rainfall, and other agronomic and environmental conditions. See the APPLICATION RATE TABLE for maintenance application rates.
