Abstract

Attempts were made to extend the storage life of seed potatoes by treating them with trace elements as antimicrobial and antisprouting agents. In tests to measure the growth of Fusarium oxysporum and Erwinia carotovora subsp. carotovora, it was found to be decreased more by iron, copper and zinc than by boron, manganese and molybdenum. Dipping seed tubers in aqueous solutions of trace element salts decreased both sprouting and microbial spoilage during storage at ambient conditions. Field testing at the end of storage showed that treating seed potatoes with ferrous sulfate did not decrease the yield of tubers or increase their iron content. It is suggested that elements may be used to extend the storage life of seed potato tubers, in tropical conditions.
