Polymorphs of 2-(3-cyano-4-isobutyloxyphenyl)-4-methyl-5-thiazolecarboxylic acid and method of producing the same

A plant metabolism regulating agent comprising as an active ingredient an alpha,beta or beta,gamma-un-saturated carboxylic acid or its derivative. It is useful for controlling the metabolism of a plant, facilitating the growth of a beneficial plant such as cereals by inhibiting the growth of undesirable plants or eradicating them, regulating the growth of a plant and dwarfing a plant.

Regulation of plant metabolism by alpha, beta-or beta, gamma-unsaturated

A plant growth promoter comprising as an active ingredient for plant growth promotion at least one phenylglycine selected from the group consisting of
