Abstract
Fungicidal compositions for the protection of turfgrass against crown and root rot are disclosed. The compositions comprise, as the active material, a mixture of (a) a monoester salt of a phosphorous acid (preferably aluminum ethyl phosphite), and (b) an ethylene bisdithiocarbamate contact fungicide (preferably manganese-zinc ethylene bisdithiocarbamate). Preferred compsitions comprise one part by weight of the monosester salt to two parts by weight of the ethylene bisdithiocarbamate.
Claims19
A process for treating turfgrass to enhance turf quality which comprises applying to said turfgrass in an amount effective to enhance turf quality:
- (a) one part by weight of a monoester salt of a phosphorous acid of formula (I):
- ##STR2## in which R is an alkyl radical having 2 to 4 carbon atoms,
- Me is an alkali metal, alkaline earth, or aluminum atom, and
- n is a whole number from 1 to 3 equal to the valence of Me;
- and
- (b) from 1.5 to 2.5 part by weight of an ethylene bisdithiocarbamate contact fungicide selected from the group consisting of manganese ethylene bisdithio-carbamate and manganese-zinc ethylene bisdithiocarbamate.
A process for treating turfgrass to enhance turf quality which comprises applying to said turfgrass in an amount effective to enhance turf quality:
- (a) one part by weight of a monoester salt of a phosphorous acid of formula (I):
- ##STR3## in which R is ethyl,
- Me is an aluminum atom, and
- n is 3;
- and
- (b) from 1.5 to 2.5 part by weight of an the contact fungicide manganese-zinc ethylene bisdithiocarbamate;
- wherein said applying step is carried out by applying said contact fungicide and said monoester salt to said turfgrass together in a common carrier.
