    • PROBLEM TO BE SOLVED: To provide agrochemicals and the like utilizing the effect of induction of systemic acquired resistance of plants, and to provide a proliferation inhibitor not only to plant pathologenic bacteria but also to harmful microbes.
      SOLUTION: Rare sugars are used for inducing a systemic acquired resistance to plants or for suppressing proliferation of microbes. Compositions having these rare sugars as effective components are used as agrochemicals utilizing the effect of induction of systemic acquired resistance of plants; plant disease suppressing agents; and agents for inducing plant growth control factors such as for disease resistance, pest resistance, maturing of fruits, dormant breaking, germination control, dryness resistance, and also environmental stress resistance such as low temperature resistance, high temperature resistance, salts resistance, heavy metal resistance, and an agent for inducing phytohormone-like action comprising promotion of flowering; and also as proliferation inhibitor of microbes. The rare sugars are aldoses such as D-allose, D-altrose, or L-galactose; or ketoses such as D-psicose, or a mixture of D-psicose and D-fructose.

    • PROBLEM TO BE SOLVED: To provide a novel disaccharide containing a rare saccharide as a constituent monosaccharide; and its synthetic method. SOLUTION: The novel disaccharide containing a rare saccharide as a constituent monosaccharide is α-D-glucopyranosyl-(1→2)-β-D-psicofuranoside with a molecular weight of 342.30. The novel disaccharide is synthesized by using sucrose as a starting material and by the coupled reaction of sucrose phosphorylase with D-tagatose 3-epimerase in the presence of an inorganic phosphoric acid. Another synthetic method is also provided, by which the novel disaccharide is synthesized by causing sucrose phosphorylase to act on α-glucose-1-phosphoric acid and a ketohexose selected from rare saccharides. The ketohexose selected from rare saccharides is at least one ketohexose selected from the group consisting of D-psicose, D-tagatose, D-sorbose, L-fructose, L-psicose, L-tagatose, and L-sorbose.
