Abstract: Potato quality is improved by applying to the plant or to the locus of the plant a composition comprising (a) a compound capable of forming a chelate with iron or (b) a chelate of iron with a chelate-forming compound. Specific quality improvements include increasing the dry matter content, increasing the starch content and reducing the reducing sugar content. A preferred iron chelate is that of EDDHA, available commercially as SEQUESTRENE 138 Fe 100.

Abstract: Grape sugar development is improved by applying to the vine or to the locus of the vine a composition comprising an iron chelate. Advantages include increasing the overall sugar content of grapes and increasing the rate of development the sugar. A preferred iron chelate is the iron chelate of EDDHA, available commercially as SEQUESTRENE 138 Fe 100.
