The invention relates to triazolopyrimidines of the formula I in which the index n and the substituents R, R<SUP>1</SUP>, R<SUP>2 </SUP>and X are as defined below: X is nitro, a group -C(S)NR<SUP>3</SUP>R<SUP>4</SUP>, a group -C(-N-OR<SUP>5</SUP>)(NR<SUP>6</SUP>R<SUP>7</SUP>) or a group -C(-N-NR<SUP>8</SUP>R<SUP>9</SUP>)(NR<SUP>10</SUP>R<SUP>11</SUP>), R is halogen, cyano, hydroxyl, cyanato, alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, alkoxy, alkenyloxy, alkynyloxy, haloalkoxy, cycloalkyl, cycloalkenyl, cycloalkoxy, alkoxycarbonyl, alkenyloxycarbonyl, alkynyloxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, alkoximinoalkyl, alkenyloximinocarbonyl, alkynyloximinoalkyl, alkylcarbonyl, alkenylcarbonyl, alkynylcarbonyl, cycloalkylcarbonyl, or a five- to ten-membered saturated, partially unsaturated or aromatic heterocycle which contains one, two, three or four heteroatoms from the group consisting of O, N or S; R<SUP>1 </SUP>is alkyl in which one carbon atom may be replaced by a silicon atom, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, phenyl, naphthyl, or a five- to ten-membered saturated, partially unsaturated or aromatic heterocycle which is attached via a carbon atom and which contains one, two, three or four heteroatoms, independently of one another selected from the group consisting of O, N and S, as ring members; where R<SUP>1 </SUP>may be substituted as defined in the description; R<SUP>2 </SUP>is alkyl, alkenyl or alkynyl which may be substituted as defined in the description; R<SUP>3</SUP>, R<SUP>4</SUP>, R<SUP>5</SUP>, R<SUP>6</SUP>, R<SUP>7</SUP>, R<SUP>8</SUP>, R<SUP>9</SUP>, R<SUP>10 </SUP>and R<SUP>11 </SUP>are, independently of one another, selected from the group consisting of hydrogen, alkyl, cycloalkyl, alkenyl or alkynyl, where the 4 lastmentioned radicals may be substituted as defined in the description; or R<SUP>3 </SUP>and R<SUP>4</SUP>, R<SUP>6 </SUP>and R<SUP>7</SUP>, R<SUP>8 </SUP>and R<SUP>9 </SUP>and/or R<SUP>10 </SUP>and R<SUP>11 </SUP>together with the nitrogen atom to which they are attached form a four-, five- or six-membered saturated or partially unsaturated ring which may be substituted as defined in the description; and n is 0 or an integer 1, 2, 3 or 4; and the agriculturally acceptable salts thereof, to crop protection compositions comprising at least one compound of the formula I and/or an agriculturally acceptable salt thereof and at least one liquid or solid carrier and to a method for controlling phytopathogenic harmful fungi.
