Process for combating overwintering fungal diseases in trees by spraying the trees while in the dormant phase with an aqueous composition containing particular surface active agents, e.g. sodium dodecylbenzenesulphonate.

Process for combating fungi

Pyrimidine derivatives are provided wherein the 6-position carries the group OSO.sub.2 NR.sup.5 R.sup.6 and the 2-position carries the group NR.sup.1 R.sup.2. R.sup.1 and R.sup.2 are preferably hydrogen or lower alkyl but both are not hydrogen and R.sup.5 and R.sup.6 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.

Pyrimidine sulfamate fungicides

Compositions containing certain surface active agents are used to combat overwintering fungal diseases in plants. Particularly perferred surface active agents are condensates of alkyl phenols or straight or branched chain fatty alcohols with from 3 to 50 moles of ethylene oxide.
