COMPOSITION AND METHOD OF SPROUT INHIBITION IN POTATOES

摘要

Compositions which include a mixture of CIPC and at least one substitutednaphthalene are disclosed. The compositions of the presentinvention are adapted for inhibiting sprout growth in tubers. When so used,the preferred substituted naphthalene in the compositions of thepresent invention are dimethylnaphthalene (DMN) and diisopropylnaphthalene(DIPN). A method of applying a CIPC/naphthalene mixtureis also disclosed. In a preferred embodiment of the method, tubers to beplaced in storage are treated with a composition of C1PC and asubstituted naphthalene utilizing thermal fogging techniques, with the averageeffective residue of CIPC on the tubers of from approximately21 ppm to 2.5 ppm. In the preferred embodiment, the weight ratio of averageeffective residue of CIPC to the substituted naphthalene isfrom approximately 1:1 to 1:4. In a most preferred embodiment, a compositionincluding CIPC and either DIPN or DMN is applied totubers utilizing thermal fogging techniques to obtain an average effectiveresidue on the outer surface of the tubers of approximately 14ppm C1PC and 14 ppm of the DIPN or DMN.
