Abstract
A method of treating potatoes sequentially with chemically-different sprout inhibitors is disclosed. Sprouting of stored potatoes may be eliminated or minimized by a treatment with CIPC followed sometime later by a treatment with a substituted naphthalene such as 1,4-DMN. Also, an initial treatment with 1,4-DMN soon after the potatoes are harvested may be advantageous in addition to the later treatments with CIPC and 1,4-DMN.
Claims2
A method of inhibiting sprout formation in tubers during storage and post-storage comprising:
- a) applying a first treatment of DMN at an application rate of less than about 20 ppm to effect a residue on said potatoes of about 0.5 ppm to about 2 ppm to the potatoes while said potatoes are still healing cuts and bruises;
- b) applying a first treatment of CIPC to the potatoes after healing has occurred in an amount to form a residue of about at least about 4 ppm after said first DMN treatment;
- and
- c) applying a second treatment of DMN at an application rate of less than about 20 ppm to the potatoes after said CIPC treatment to effect a residue on said potatoes of about 0.5 ppm to about 2 ppm.
