Pyrimidine derivatives are provided wherein the 6-position carries the group OSO2NR5R6 and the 2-position carries the group NR1R2. R1 and R2 are preferably hydrogen or lower alkyl but both are not hydrogen and R5 and R6 are preferably lower alkyl, although these groups may form a cyclic ring. The 3-position and 4-position are preferably substituted with lower alkyl, although lower alkynyl or alkenyl may be used. The derivatives are compounded into compositions for combatting fungal pests. |
