Abstract
Compounds of the formula ##EQU1## wherein R is hydrogen; alkyl of 1 to 13 carbon atoms; alkyl of 1 to 13 carbon atoms substituted with alkoxycarbonyl of 2 to 4 carbon atoms, acyl of 2 to 4 carbon atoms, cyano, hydroxyl, acyloxy of 2 to 4 carbon atoms, ##SPC1## R.sub.1 is hydrogen, ##EQU2## X is oxygen or sulfur WITH THE PROVISO THAT 1. when R.sub.1 is ##EQU3## or when X is sulfur, R is methyl; 2. WHEN R is a cation, R.sub.1 is hydrogen; 3. when R is substituted alkyl, the total number of carbon atoms in R is less than 14; Such as 2-cyano-2-hydroxyiminoacetamide and 2-cyano-N-ethylcarbamoyl-2-methoxyiminoacetamide are useful in preventing fungus diseases in plants.
