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.
Claims24
A method of inhibiting sprouting in potato tubers during storage, comprising
- simultaneously or substantially simultaneously applying during storage of the potato tubers a composition comprising
- i) one or more sprout inhibiting agents selected from the group consisting of
- α,β-unsaturated aliphatic aldehydes;
- α,β-unsaturated aliphatic ketones;
- C3 to C14 saturated aliphatic aldehydes;
- C3 to C14 saturated aliphatic ketones;
- C3 to C14 saturated or unsaturated aliphatic primary alcohols;
- C3 to C14 saturated or unsaturated aliphatic secondary alcohols;
- and
- ii) one or more sprout inhibitors selected from the group consisting of chlorpropham (CIPC), dimethylnaphthalene (DMN), diisopropylnaphthalene (DIPN), carvone, and an essential oil.
A method of inhibiting sprouting in potato tubers during storage, comprising
- applying one or more sprout inhibitors selected from the group consisting of chlorpropham (CIPC), dimethylnaphthalene (DMN), diisopropylnaphthalene (DIPN), carvone, and an essential oil to the potato tubers after wound healing and prior to sprouting at a rate that is lower than a label rate, and, when sprouts begin to appear,
- applying during storage of the potato tubers one or more sprout inhibiting agents selected from the group consisting of
- α,β-unsaturated aliphatic aldehydes;
- α,β-unsaturated aliphatic ketones;
- C3 to C14 saturated aliphatic aldehydes;
- C3 to C14 saturated aliphatic ketones;
- C3 to C14 saturated or unsaturated aliphatic primary alcohols;
- and
- C3 to C14 saturated or unsaturated aliphatic secondary alcohols.
A composition for inhibiting sprouting of potato tubers during storage, comprising
- i) one or more sprout inhibiting agents selected from the group consisting of
- C8-C14 saturated or unsaturated aliphatic primary alcohols;
- and
- C8-C14 saturated or unsaturated aliphatic secondary alcohols;
- and
- ii) one or more sprout inhibitors selected from the group consisting of chlorpropham (CIPC), dimethylnaphthalene (DMN), diisopropylnaphthalene (DIPN), carvone, and an essential oil.
