The present invention relates to a plant disease control agent containing a compound represented by the following formula (1) or salt thereof as an active ingredient (in the formula, Rand Rrepresents a hydrogen atom or methyl group but excepting cases where Rand Rare the same), a plant disease controlling method applying the plant disease control agent on plants suffering from diseases, and a novel compound represented by formula (1) or salt thereof. 

Plant disease control agent

A microorganism selected from the group consisting of asp. ITB090 strain (NITE BP-01725), asp. ITB100 strain (NITE BP-01726), and asp. ITB105 strain (NITE BP-01727), or a variant strain derived therefrom is used to control plant diseases, control nematodes, promote plant growth, and the like.

Method of promoting plant growth

The present invention relates to thesp. strains AT-332 (NITE BP-1095) and AT-79 (NITE BP-1094) isolated from nature; and a plant disease control agent, a nematode control agent and a plant growth promoter containing the strains as active bacteria. Thesp. strains AT-332 and AT-79 strain are effective in controlling both a wide range of various plant diseases and nematode-damage and capable of promoting the growth of useful plants, due to a culture containing a secondary metabolite of the strains or cultivated and isolated live bacteria of the strains being introduced to a plant body or to the culture soil.

[object Object]

An inhibitor for tobacco axillary bud growth, containing chlorthal-dimethyl and aliphatic alcohol selected from decyl alcohol, 2-ethyl hexanol and geraniol in combination; and a method for inhibiting tobacco axillary bud growth, which includes applying the inhibitor for tobacco axillary bud growth.

Tobacco axillary bud growth inhibitor and method for inhibiting tobacco axillary bud growth

An inhibitor for tobacco axillary bud growth, the inhibitor containing one or more cell division inhibitors selected from pyridine-based compounds and benzamide-based compounds. This inhibitor may further include an aliphatic alcohol having 6 to 20 carbon atoms in combination with the one or more cell division inhibitors.

Tobacco axillary bud inhibitor and tobacco axillary bud-inhibiting method

The present invention relates to an inhibitor for tobacco axillary bud growth, the inhibitor comprising, as an active ingredient, one or more kinds of very-long chain fatty acid synthesis inhibitors such as a chloroacetamide-based herbicide, fentrazamide, cafenstrole or indanofan; an inhibitor for tobacco axillary bud growth, the inhibitor comprising the aforesaid very-long chain fatty acid synthesis inhibitor together with clorthal-dimethyl or an aliphatic alcohol having 6 to 20 carbon atoms; and a method for inhibiting tobacco axillary bud growth which comprises applying the inhibitor for tobacco axillary bud growth. The inhibitor for tobacco axillary bud growth of the present invention shows sustained drug efficacy at a low concentration, induces neither chemical injury nor disease, and can contribute to the improvement in labor productivity.
