Filed:

Dec 13, 2001

Appl. No.:

10/450233

Inventors:

Norman R. Knowles - Pullman WA, US
Lisa O'Rear Knowles - Pullman WA, US

Assignee:

Washington State University Research Foundation - Pullman WA

International Classification:

A01N035/02

US Classification:

504348

Abstract:

The present invention provides methods for inhibiting sprouting of potato tubers, the methods each including the step of contacting a potato tuber with an amount of a chemical agent including at least one aliphatic carbonyl compound selected from the group consisting of a Cto C, α,β unsaturated aliphatic aldehyde and a Cto C, α,β unsaturated aliphatic ketone, wherein the amount of the chemical agent is effective to inhibit potato tuber sprouting. Some aldehydes and ketones useful in the practice of the present invention are defined by formulae I and II, respectively, as set forth herein. In the practice of the methods of the invention the chemical agent is applied after the potato tubers have been harvested, but typically not later than the onset of sprouting.

Assignee:

WASHINGTON STATE UNIVERSITY - Pullman WA

International Classification:

A23B 7/154

US Classification:

426321, 426654

Abstract:

Compositions and methods for inhibiting the sprouting of potato tubers are provided. The compositions comprise combinations of i) α,β-unsaturated aliphatic aldehydes, and ketones,C3 to. C14 aliphatic aldehydes and ketones, and/or C3 to C7 saturated or unsaturated primary and secondary aliphatic alcohols; and 2) conventional sprout Inhibitors, The effect of the combinations is additive and/or synergistic, and less of the conventional inhibitor is required to achieve the same or improved levels of sprout inhibition.
