Vivando Fungicide (metrafenone), EPA# 7969-284, READ THE LABEL
Vivando provides excellent control of powdery mildew with protectant, post-infection, and antisporulant activity, with moderate to high risk of disease resistance development. Apply at 10.3 to 15.4 fluid ounces per acre per application on a 14 to 21 day schedule (use of the lower rate on a 14 day schedule is typical in New York State), and no more than 46.2 fluid ounces per acre per season. Do not make more than 2 sequential applications before alternating with another effective powdery mildew fungicide, and do not make more than 3 application per season. The minimum interval between applications is 14 days. Vivando is unrelated to any other fungicide product currently in the market, so use in a rotational program with other effective powdery mildew fungicides is a good resistance management strategy. 12 hour reentry interval, 14 days to harvest.
