Application was straightforward, and I did notice some reduction in growth rate, which meant slightly less mowing. That part held true—this product is designed to slow vertical growth and redirect energy into thicker turf, and it does seem to help in that regard. That said, the overall effect felt a bit more subtle than expected. I was hoping for a more noticeable difference in growth suppression and lawn appearance, but the results were somewhat modest on my lawn. It may work better with very consistent applications or under ideal conditions, but it wasn’t a dramatic transformation for me. ## Frequently Bought Together - Primo Maxx Plant Growth Regulator - Southern Ag Chelated Liquid Iron, 1 Gallon --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nz/products/451849633-syngenta-primo-maxx-plant-growth-regulator](https://www.desertcart.nz/products/451849633-syngenta-primo-maxx-plant-growth-regulator) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-04-25*
