ABSTRACT:
Oxalyl hydrazide-hydroxamic acid derivatives of the formula I ##STR1## where the substituents have the following meanings: R, R.sup.1, R.sup.2 and R.sup.3 independently of one another are
hydrogen, substituted or unsubstituted alkyl, alkenyl or alkynyl or
substituted or unsubstituted cycloalkyl or cycloalkylmethyl,
substituted or unsubstituted cycloalkenyl or cycloalkenylmethyl,
substituted or unsubstituted phenyl, phenylalkyl, phenylalkenyl, hetaryl- or hetarylalkyl radicals, where R.sup.2 and R.sup.3 may also. together with the nitrogen atom whose substituents they are, form a 5- or 6-membered ring, or
R.sup.2 together with R.sup.3 is the group ##STR2## where R.sup.4 and R.sup.5 are one of the radicals R, R.sup.1, R.sup.2 or R.sup.3, or R.sup.4 together with R.sup.5 and the carbon atom whose substituents they are, are monocyclic or polycyclic cycloalkyl, or
R.sup.4 together with R.sup.5 and the carbon atom whose substituents they are, form a 5- or 6-membered, saturated heterocycle containing O, S or --N(R.sup.6)-- as a hetero group, and fungicides containing these active ingredients.
