The invention relates to 5-alkyl-7-aminotriazolopyrimidines of the formula (I) and to the salts thereof. In said formula substituents have the following meanings: R1 and R2 each is a hydrogen atom or a group of alkyl, alcenyl, alcynyl, haloalkyl, cycloalkyl, phenyl or naphtyle, saturated, unsaturated or aromatic heterocycle having from five to six members which contain from one to four nitrogen atoms or one to three nitrogen atoms and one sulfur or oxygen atom, or R1 and R2 can form together with a connecting them nitrogen atom a cycle of 5 to 6 members containing from one to four nitrogen atoms or from one to three nitrogen atoms and one sulfur or oxygen atom, R3 is a cycloalkyl or bicycloalkyl group, R1, R2 and R3 can be substituted in conformity with a description, and X is an alkyl or alkyl halide group. The inventive methods and intermediary products necessary for producing said compounds, agents containing them and the use thereof for fighting against harmful mushrooms are also disclosed.

L'invention concerne des 5-alkyl-7-aminotriazolopyrimidines de formule (I), ainsi que les sels de ces composés. Dans ladite formule, les substituants ont les significations suivantes : R?1¿ et R?2¿ représentent chacun un atome d'hydrogène ou un groupe alkyle, alcényle, alcynyle, haloalkyle, cycloalkyle, phényle ou naphtyle, un hétérocycle saturé, insaturé ou aromatique à cinq ou six membres contenant un à quatre atomes d'azote ou un à trois atomes d'azote et un atome de soufre ou d'oxygène, ou R?1¿ et R?2¿ peuvent former avec l'atome d'azote qui les relie un cycle à cinq ou six membres contenant un à quatre atomes d'azote ou un à trois atomes d'azote et un atome de soufre ou d'oxygène, R?3¿ représente un groupe cycloalkyle ou bicycloalkyle, R?1¿, R?2¿ et R?3¿ pouvant être substitués conformément à la description, et X représente un groupe alkyle ou halogénure d'alkyle. L'invention concerne également des procédés et des produits intermédiaires nécessaires à la production de ces composés, des agents contenant ces composés et leur utilisation pour lutter contre des champignons nocifs phytopathogènes.
