Frequently Asked Questions

Q: What is Trinexapac-Ethyl and how does T-Nex work?
A: Trinexapac-ethyl is a gibberellin biosynthesis inhibitor. T-Nex slows vertical shoot growth by blocking the plant’s ability to produce gibberellin hormones, resulting in slower, more compact turf growth with improved stress tolerance and visual quality.

Q: How does T-Nex compare to Primo Maxx?
A: T-Nex contains the same active ingredient (trinexapac-ethyl 12%) as Primo Maxx but is available at a more competitive price point. It delivers equivalent performance for professional turf management programs.

Q: What grasses can I apply T-Nex on?
A: T-Nex is labeled for use on bermudagrass, zoysiagrass, Kentucky bluegrass, perennial ryegrass, tall fescue, fine fescue, and creeping bentgrass among other turf species. Always consult the label for full use-site and grass-type listings.

Q: How much T-Nex do I need per acre?
A: Application rates vary by grass type and desired growth suppression. Common rates for cool-season turf range from 0.25 to 0.5 oz per 1,000 sq ft (1–2 fl oz per 1,000 sq ft depending on conditions). Refer to the label for precise rates.
