A maximum of twice the recommended Quali-Pro T-Nex rate from the Application Rate Table may be applied in order to ensure extended growth suppression of up to 8 weeks and when temporary discoloration can be tolerated, otherwise the use rates lead to approximately 50% growth inhibition over a 4-week period.

1. Mow 4 hours after the application of Quali-Pro
T-Nex should be applied 1 to 5 days before seeding and before verticutting, scalping, spiking, or other similar operations. T-Nex is foliarly-absorbed; therefore, it does not affect seed germination.
The application rates for Quali-Pro T-Nex vary depending on the type of turfgrass you have. You can view these rates on the chart on pages 6-7 of the product label here. Please let us know if you need further assistance.
The grass needs to be actively growing for a T-Nex application to be effective and useful. So if you are applying now, that would likely be your last application for the year since the T-Nex can last 8 weeks, and you would not apply after frost.
When treating Bahia grass with T-Nex use one ounce per 1,000 sqft.
We recommend that you identify what type of desirable turf you have prior to applying T-Nex to your grass.
T-Nex Plant Growth Regulator is measured in oz per 1,000 feet and not oz per gallon. Most people will measure off 1,000 sq, fill their tank with water, then walk and spray at a normal pace. If at the end, you find it takes you 1 gallon of water to cover 1,000 sq then that is how much water you use when mixing and so forth and so on. Typically it takes about 1-3 gallons of water to cover 1,000 sq feet.
Quali-Pro T-Nex can be applied to healthy, actively growing turf before the onset of stress and may continue to be applied throughout the growing season as long as the turf remains healthy. Do not apply more than 7.0 fl oz per 1000 sq ft per year.
T-Nex is safe to use on residential centipede lawns.

The main difference between T-Nex and Ethephon 2SL besides the active ingredient is that T-Nex is only for use as a growth regulator for turfgrasses. Ethephon is labeled is labeled to also be used to prevent undesirable fruit on certain trees, mistletoe removal and turfgrass growth, but not on residential lawns.
You can add iron (or quick-release Nitrogen) to an application of T-Nex Plant Growth Regulator in accordance with the product label to reduce any potential discoloration. Discoloration to actively growing turfgrass should last only about a week, if there is any at all. Typically you would not reduce the label rates when applying T-Nex unless the turf were growing under stress from factors such as low fertility or compaction. If you can tolerate some discoloration, then you can actually apply up to twice the listed rate (1.2 oz per 1,000 sq ft on KBG) to get control for up to 8 weeks.
We recommend that you calibrate your sprayer with just water if you are not sure how much water you need to cover your lawn. We have a video here to assist you with how to calibrate your sprayer.
The discoloration can last for a few weeks after applying T-Nex Plant Growth Regulator. The application rate will depend on your needs. Please read over the full product label to find the correct rates for your applciation:
T-Nex Plant Growth Regulator should be applied when the lawn if actively growing and will last for 8 weeks. Depending on the type of turfgrass you have, the application rates should be adjusted based on the grass height at application. Please view the Application Rate Table on the product label for application rates for your turfgrass. The lower the height of cut of the particular turfgrass species, the less material is required to provide the desired turf growth regulator effect.
