The Environmental Protection Agency has registered SmartBlock, a potato sprout-inhibitor from Amvac Chemical Corp., Newport Beach, Calif.

State registrations are pending.

The active ingredient, 3-decen-2-one, is a naturally occurring molecule, according to a news release.

It was discovered as a sprout inhibitor by Washington State University and licensed exclusively to Amvac.

The Food and Drug Administration already had approved it as a food additive and the EPA, a biopesticide.

It is exempt from tolerances.

SmartBlock works by burning off peeping sprouts. It only targets the actively growing sprout tissue.

When applied through typical fogging equipment, it forms true vapor, moving throughout the potato pile.

CIPC, the potato industry's main sprout inhibitor, is under fire from the EPA, because it's a carbamate—an older chemical class.
