TebuStar 45WSP (tebuconazole), EPA# 42750-102, READ THE LABEL Tebuconazole provides effective control of powdery mildewand black rot with post-infection, antisporulant, and limited protectant activity, with moderate risk of disease resistance development. Apply TebuStar at 4 oz. per acre per application and a maximum or 2 pounds per season. For powdery mildew control, apply on a protective schedule with applications made 14 days (preferable in mostcircumstances) to 21 days apart. For black rot control, apply on a 7 to 14 day schedule, OR within 72 hours of the start of an infection period, but not within 7 days of a previous application. Tebuconazole is a sterol inhibitor (DMI) fungicide, and powdery mildew resistance to the DMI fungicidesis common where they have been used for several years. Use a good resistance management strategy in your vineyard by limiting the number of DMI applications to a maximum of 3 per year, and use a rotational program with other non-DMI powdery mildew fungicides. Rotating with other DMI fungicidesis NOT an effective disease resistance management approach. 12 hour reentry interval, 14 days to harvest. 2 pounds in 2 ounce water soluble packets Material Safety Data Sheet: Tebustar MSDS.pdf
