  • Patent number: 7913453
    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.

  • Publication number: 20070261453
    Abstract: The invention relates to novel mixtures of N,N?-ethylene-bis(hydroxyphenyl)glycines comprising a mixture of o,p-and o,o-isomers, wherein the ratio of o,pto o,o-isomer is higher than 0.8:1. The novel mixtures have improved characteristics for supplying crop plants with essential metal chelates required as plant nutrients. With the novel mixtures, in particular the short-term supply of metal chelates is improved, while the long term supply is maintained as for known chelating agents comprizing only the o,o-isomer of N,N?-ethylene-bis(hydroxyphenyl)glycine. The invention further refers to metal complexes of the isomer mixture, their use in the field of agriculture as plant nutrient or as component of fertilizers for plants and for treatment of chlorosis in crop plants.
