DESCRIPTION:

BRIEF SUMMARY
TITLE OF THE INVENTION

1. Field of the Invention
The present invention relates to novel phenylalkane amide derivatives and agricultural or horticultural fungicides containing the same as active ingredients.
2. Description of the Background
Heretofore, N-phenylacetaminonitriles such as N-(1-cyano-1-cyclopropylethyl)-2-(2,4-dichlorophenyl)acetamide and the like have been known as the intermediates of 3-arylpyrrolidin-2,4-diones (Japanese Patent Application, First Publication, No. Hei 6-220004 and Japanese Patent Application, First Publication, No. Hei 6-263731); however, the utility of the compounds as agricultural or horticultural fungicides are not known at all.
Recently, the fungicidal activities of the conventional fungicides may become degraded because of the emergence of resistant fungi after repeated use of the fungicides. For this reason, as well as because of environmental problems, it is desired to provide a novel fungicide which can efficiently control harmful fungi even at a low concentration.
In order to develop an agent having a superior fungicidal activity in comparison with the conventional fungicides, the present inventors have synthesized various novel phenylalkane amide derivatives and have carried out extensive research in connection with their effects on the biological activities of fungi. As a result, the present inventors have found that the novel compounds according to the present invention exhibit excellent fungicidal activities with regard to rice blast and the like, while at the same time do not hinder desirable plant growth.
