Abstract

Novel Substituted benzoxazine derivatives of the formula ##STR1## in which X is oxygen or suophur, and R.sup.1 and R.sup.2 each independently is hydrogen, alkyl, alkoxy, akylthio, halogenoalkyl, alkanoyl, aroyl, halogen, cyano, nitro, nitroso, amino or the suophonic acid grouping, with the restriction that either of R.sup.1 and R.sup.2 does not represent hydrogen if the other represents hydrogen, the 6-methyl group, the 6-ethyl group, the 6-butyl group or the 6-acetyl group and X is oxygen, which possess fungicidal activity. A few related compounds, though known, also possess such activity.

Dependencies are inferred from the claim text.
