Claims
- 1. A pyrazolylpyrimidine of the formula ##STR44## wherein R.sub.1 is hydrogen or C.sub.1-6 alkyl, R.sub.2 is hydrogen or C.sub.1-4 alkyl, X is oxygen or sulfur and R.sub.3 is phenyl or phenyl substituted with from 1 to 3 substituents selected from the group consisting of halogen, C.sub.1 -C.sub.4 alkyl, methoxy, methylthio, cyano, nitro, trifluoromethyl and carbethoxy; provided that when R.sub.1 is C.sub.1-6 alkyl, R.sub.2 is hydrogen and X is oxygen, R.sub.3 is said substituted phenyl, and excluding pyrazolylpyrimidines where R.sub.1 is C.sub.1-6 alkyl, R.sub.2 is C.sub.1-4 alkyl and X is sulfur.
- 2. A fungicide composition comprising as active ingredient, a fungicidally effective amount of a pyrazolylpyrimidine of the formula ##STR45## wherein R.sub.1 is hydrogen or C.sub.1-6 alkyl, R.sub.2 is hydrogen or C.sub.1-4 alkyl, X is oxygen or sulfur and R.sub.3 is lower alkyl, phenyl or phenyl substituted with from 1 to 3 substituents selected from the group consisting of halogen, C.sub.1-4 alkyl, methoxy, methylthio, cyano, nitro, trifluoromethyl and carbethoxy; provided that when R.sub.1 is C.sub.1-6 alkyl, R.sub.2 is C.sub.1-4 alkyl and X is sulfur, R.sub.3 is ethyl or when R.sub.1 is C.sub.1-6 alkyl, R.sub.2 is hydrogen and X is oxygen, R.sub.3 is said substituted phenyl in a suitable carrier.
