METHOD OF CONTROLLING SPROUT FORMATION IN POTATOES BY SELECTIVE APPLICATION OF CHLORPROPHAM, CARVONE, BENZOTHIAZOLE AND ETHYLENE

摘要

A method of controlling sprout formation in tubers includes application of CIPC and carvone or application of CIPC and benzothiazole and then storing the treated tubers. In a preferred embodiment of the method , tubers to be placed in storage are treated with a composition of CIPC and carvone or CIPC and benzothiazole utilizing thermal fogging techniques, with the average effective residue of C1PC on the tubers of approximately 16.6 ppm. When the tubers are to be used to grow tub er- producing plants, for example, when the tubers are to be used as seed potatoes, after removal from storage, the seed potatoes are treated with ethylene at planting, thereby stimulating sprout growth.
