Fungicidal compositions for the enhancement of turf quality

摘要

Fungicidal compositions for the protection of turfgrass against crown and root rot are disclosed. The compositions comprise, as the active material, (a) a monoester salt of a phosphorous acid (preferably aluminum ethyl phosphite), (b) an ethylene bisdithiocarbamate contact fungicide (preferably manganese-zinc ethylene bisdithiocarbamate), and (c) a benzoporphyrin compound. Preferred compositions comprise 1 part by weight of the monoester salt, 2 parts by weight of the ethylene bisdithiocarbamate, and between about 0.01 and about 0.1 parts by weight of the benzoporphyrin compound.
