Reason Registered for Early, Late and Tuber Blight

REASON, from Bayer CropScience, has been registered by the EPA for preventing early, late and tuber blight. REASON is classified as a reduced-risk fungicide.

With REASON, growers now have a locally-systemic, foliar fungicide with strong translaminar and anti-sporulant properties that kill at multiple stages during the pathogen life cycle,” said Rob Schwehr, product manager with Bayer CropScience. “REASON is a reduced-risk product that provides a fast-acting, consistently high level of control against the most economically important diseases of potatoes.”

The active ingredient, fenamidone, acts by disrupting electron transport in the mitochondria, effectively stopping disease before it can spread to healthy leaf tissue.

“This preventative activity, combined with a strong spore-killing effect, provides better protection than competing products,” Schwehr said.

REASON may be applied at a rate of 5.5 ounces to 8.2 ounces per acre with a length of control of five days to 10 days. REASON can be applied by ground, air or chemigation. A high-quality spreader/sticker, approved for use on growing crops, should be used with REASON.

REASON has demonstrated consistent, reliable control in nationwide external and internal field trials since 1999. Tests show that REASON provides potato growers many benefits, including penetrating leaf tissue to protect both sides of the leaf. REASON moves into new growth to protect new leaves and shoots at a competitive cost per acre with low use rates.

“REASON exhibits limited curative performance properties. However, Bayer CropScience strongly recommends applying REASON prior to the onset of disease for better overall protection of your crop,” Schwehr said.
