Zusammenfassung:	New 1-(2-cyano-2-hydroxyimino-acetyl)- 3-cycloalkyl-urea derivs. are cpds. of the formula R1-NH-CO-NH-CO-C(CN):N-OR (I) and their salts and complexes (where R is H or Me and R1 is 5-12C cycloalkyl opt. substd. by 1-4C alkyl or 1-4C alkoxy). (I) are pesticides with strong fungitoxic activity against phytopathogenic fungi. In some cases they have curative activity. Rate of application is 0.1-5 kg/ha. In an example, a 0.2% dispersion of (I; R is Me, R1 is cyclohexyl) is sprayed on to vine plants which are kept 10 days, then artificially infected with Plasmopara viticola and kept 11 days under greenhouse conditions, only 15% of leaves show signs of fungal infection whereas in untreated controls the degree of infection is 70%.
