For superintendents looking for an effective and easy-to-use fungicide, ArmorTech Prothio 4L, by United Turf Alliance, is an excellent choice. It is safe for use on cool- and warm-season turf, features one low rate, and provides curative and preventative protection against some of the toughest diseases golf courses can encounter.
Powerful and Broad-Spectrum
Prothio 4L is a liquid, demethylation inhibitor-based (DMI) fungicide and is powered by prothioconazole (41%). This active ingredient fights hard-to-control diseases like dollar spot, brown patch, and anthracnose. It also controls a variety of other diseases, including fairy ring, mini-ring, and large patch. For a full list of controlled diseases—15 in total—see pages 10-12 of Prothio 4L’s label.
One Low Rate
Prothio 4L makes things easy for applicators with its use rate of 0.195 fluid ounces per thousand square feet—regardless of the disease being treated. The product should be applied in a minimum of 40 gallons of spray solution per acre for complete, uniform coverage. Retreatment timing varies between 14 and 28 days after the initial application, depending on the disease being treated.
See the “Use Information” column on pages 10-12 of the label for additional application protocols, including which diseases require preventative applications and which diseases require the product to be watered in.
