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. COPYRIGHT: (C)2006,JPO&NCIPI
