Prosper® 500 EC is a Froup 5 fungicide treatment to establish early-season powdery mildew control.

Prosper is best used for disease prevention and is one of the few fungicides used on powdery mildew that can reduce very low level new infections on the green foliage.

When applied to vineyards, 30% of the active ingredient is taken up into the vine within 10 minutes, with the remainder being almost completely taken up within 3 hours.
