T-Nex Plant Growth Regulator
Quali-Pro T-Nex Plant Growth Regulator helps to impact the growth cycle of plants by minimizing the labor of growth and improving the warm- and cool-season quality of turf grasses. T-Nex contains 12% Trinexapac-ethyl as its active ingredient and works well to control grass foliage absorption in various areas such as lawns, turfs, and golf courses.

T-Nex Plant Growth Regulator, manufactured by Quali-Pro, is a micro-emulsion concentrate (with an active ingredient of 12% Trinexapac-ethyl) used to control the rate of growth and quality of cool and warm-season turf grasses. T-Nex is primarily used as a liquid plant growth regulator to control some of the turf's color quality, lateral stems, and root mass development.
T-Nex PGR is easy to measure and regulate turf grasses and lawns. It is formulated as a micro-emulsion, so it mixes thoroughly with water. It can be used as a tank companion to other pesticides and liquid fertilizers.
Because T-Nex is a plant growth regulator, it reduces the warm and cool season grass growth rate, minimizing the need for edging and mowing turfgrass. It also helps to withstand the stress of seasonal heat.
T-Nex Plant Growth Regulator is also durable as it will not easily wash off with rain after 3 hours of application.
Tools Needed
You may use a handheld pump sprayer, hose-end sprayer, backpack sprayer, or spray rig.
How to Use
- Step 1: Determine how much T-Nex Plant Growth Regulator you will need by measuring the square footage of the treatment area. To do this, measure the length and width of the area to be treated in feet, then multiply them together (length X width = square footage). To find the acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acres). Mix rates will vary on the targeted weed and treatment area. Residential and commercial cool-seasoned turf, use 0.60 oz. of T-Nex Plant Growth Regulator per 0.5 gallon of water per 1,000 sq. ft. Residential and commercial warm-seasoned turf, use 0.10 oz. of product per 0.5 gallon of water per 1,000 sq. ft.
- Step 2: Mix and fill your sprayer halfway with water, add the required amount of T-Nex based on your treatment area, then fill your sprayer the rest of the way with water. Close the lid and shake to ensure an even mix.
- Step 3: Apply the spray mixture to the turf area, making a uniform application. Spray the turf to the point of wetness, not runoff. For remarkable results, allow the application to be completed at least 3 hours before rain.
Where to Use
Quali-Pro T-Nex Plant Growth Regulator can be used on warm and cold seasonal turfs such as Golf Courses, Rough Grass Areas, established properties of lawns, commercial and residential turfgrass, and other residencies such as Golf Courses, Sod Farms, and underdeveloped turf.
When to Use
Apply during dry or humid days when rain is not predicted. The spray mixture must be completed for at least three hours before rain or irrigation is applied to actively growing turf for best results.
Safety Information
T-Nex Plant Growth Regulator is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when applying.
Special Considerations
Since this product requires foliar contact, you want to treat the turf area sufficiently. The spray mixture will not soak thoroughly into the area, but it must rest on the surface for accurate results.
