Abstract: Disclosed herein are 4-phenylamino-3-oxazolin-5-one compounds and herbicides comprising as an essential effective ingredient 4-phenylamino-3-oxazolin-5-one compounds.

Abstract: Industrial antifungal compositions of the present invention contain as active ingredients both the compounds represented by the general formula (I) and the compounds represented by the general formula (II), said general formulas being mentioned below. By virtue of using two kinds of compounds mentioned above in combination in the compositions, antifungal properties of the present composition sharply augment and hence said compositions are found to have excellent antifungal properties as well as excellent antifungal activities against a wide variety of species of fungi and, moreover, the present compositions are excellent in safety and free from tending to accumulation. ##STR1## wherein R represents methoxycarbonylamino, ethoxycarbonylamino or 4-thiazolyl. ##STR2## wherein X represents halogen or lower alkoxy of 1 to 4 carbon atoms.
