Adjuvants selected from liquid polyalkoxylated aliphatic alcohols, solid sodium hydrocarbyl sulfonates and polyalkoxylated trisiloxanes enhance the efficacy of fungicidal triazolopyrimidines. They can be incorporated into formulations of the fungicidal compounds or be added to spray mixtures (tank mix) as separately formulated additives in order to improve the efficacy, systemicity and spectrum of these fungicides.

Enhancement of the efficacy of triazolopyrimidines

Substituted benzophenone compounds are disclosed, having the formula: ##STR1## The compounds are useful as fungicides having high systemicities.

Fungicidal 2-methoxybenzophenones

An improved process for the preparation of (S)-1,1,1-trifluoroalkyl-2-amines of formula IIIA, ##STR1## where R.sup.1 is a C.sub.1-6 alkyl group, from the corresponding racemic mixture, which process includes treating 1 part by mole of the racemic mixture with approximately 0.3 to 0.7 part by mole of D-(-)-tartaric acid in the presence of an inert solvent.

Fungicidal trifluoromethylalkylamino-triazolopyrimidines

The novel compounds of formula I: ##STR1## wherein R.sup.1, R.sup.2, Hal and L.sup.1 through L.sup.5, are defined in the specification show selective fungicidal activity.
