Posted: May 12, 2011

EPA has registered Presidio for use on cole crops, root and tuber vegetables including potato.

Valent U.S.A. Corporation just announced that Presidio fungicide has been registered by the EPA for use on cole crops including broccoli, brussel sprouts, cabbage, cauliflower, kale, etc. for managing downy mildew, damping-off caused by Pythium spp. and Phytophthora root rot. On root and tuber vegetables (beets, radish, sweet potato, etc.) it was registered for managing Pythium diseases as well as cavity spot on carrot. Presidio can also now be used for managing late blight and pink rot of potato. For pink rot, an in-furrow or side-dress application is recommended. Applications for late blight must be applied preventatively when conditions are favorable for disease development.

Presidio is a FRAC Group code 43 and for resistance management it must be tank mixed with a labeled rate of another fungicide active against the target pathogen but in a different FRAC Group code and therefore have a different mode of action. See label for rates, methods of application, REIs and PHIs. The label can be found on the CDMS website ( by selecting the labels/MSDS link under the Services tab in the upper right corner and searching for the brand name.
