There are disclosed .alpha.-(1-triazolyl)-keto-derivatives of the general formula: ##STR1## in which R is alkyl, alkenyl or phenyl optionally substituted; R' is alkoxycarbonyl, alkylcarbonyl, arylcarbonyl, aminocarbonyl or cyano; R' has the meanings of both R and R'. These compounds are endowed with high fungicidal activity.

Alpha-(1-triazolyl)-keto-derivatives having fungicidal activity

There are disclosed derivatives of five-membered nitrogen-containing heterocycles substituted on the nitrogen atom in position 1 by polyfunctional alkenyl groups. Said compounds are endowed with phytogrowth-regulating activity and, in higher doses, with herbicidal activity. A process for synthesizing the compounds and their use in agriculture are also disclosed.

Derivatives of azoles having phytogrowth regulating activity

There are disclosed N-aryl-1,3-oxazolidine-2,4-diones of the formula: ##STR1## wherein: R=C.sub.1 -C.sub.5 alkyl; C.sub.1 -C.sub.5 haloalkyl

N-Aryl-1,3-oxazolidine-2,4-diones exerting a fungicidal, systemic action

A series of condensed heterocycles, more particularly condensates of triazolones with pyrazolones, which exhibit antibotrytical activity, are disclosed. A process for producing the new heterocycles, which are pyrozolo-triazol-triones, by reacting carbethoxy pyrazolones with isocyanates, in the presence of tertiary amines, is also disclosed.
