You may notice some grassy weeds, like crabgrass, turning white in our test areas near number one tee, nine hill and between eighteen cart path and hole sixteen. This niche product has the ability to work both pre and post emergent on undesirable grassy weeds and some broadleaf weeds too. One of the pluses is its ability to be used in newly seeded areas without injuring juvenile seedlings. An application in which other crabgrass preventatives fall short.
Tenacity inhibits a plant enzyme called HPPD that is essential to photosynthesis and prevents formation of carotenoids in susceptible plant species. Without carotenoids, light energy and by-products of photosynthesis will destroy chlorophyll (the green color in leaves) and cell membranes. This results in the bleaching of leaves followed by the death of the plant.
