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.
Quali-Pro T-Nex is just a generic of the Primo Maxx with slightly more active ingredient and a different manufacturer, allowing for different rates to be used.
Quali-Pro T-Nex is applied at the rates below per 0.5-4 gallons of water per page 7 of the product label based on the type of Bermuda in your lawn.

Per the product label: T-Nex may be applied in the following manner:
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.
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.
We would suggest contacting the manufacturer Quali-Pro for instuctions on the best mix rate for Quali-Pro T-Nex to treat both both St. Augustine and Bermuda.

We recommend that you identify what type of desirable turf you have prior to applying T-Nex to your grass.
T-Nex is safe to use on residential centipede lawns.
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.
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.
When treating Bahia grass with T-Nex use one ounce per 1,000 sqft.
As long as you keep pets/children out of the area while you treat and until the T-Nex Plant Growth Regulator has had time to completely dry or settle it is safe for pets and people to return and resume normal activity typically after 4-6 hours. Always be sure to follow the product label instructions.
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.
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.
