For treating Brown Patch in turfgrass, Propiconazole 14.3 Select Fungicide is applied at the rate of 1-2 fl oz per 1000 sq ft. For prevention, begin applications in May or June before disease is present and it is recommended to tank mix Propiconazole with a registered contact fungicide such as Azoxy 2SC at the labeled rate for best results.
Under conditions of high temperatures and high humidity, use the higher rates of Propiconazole 14.3 Select Fungicide and shorter application intervals. Repeat applications every 14-21 days while disease is present is suggested. Please view the product label for more information.
