Abstract
There is described a fungicidal composition which comprises a synergistic amount of (a) propyl 3-(dimethylamino)propylcarbamate or an acid addition salt thereof, and (b) a compound selected from the group consisting of zinc propylenebis(dithiocarbamate) polymer (propineb), zinc ethylenebis(dithiocarbamate) polymer (zineb), manganese ethylenebis(dithiocarbamate) polymer (maneb), zinc ammoniate ethylenebis(dithiocarbamate)-poly(ethylenethiuramdisulphide) (metiram), tetrachloroisophthalonitrile (chlorothalonil) and copper(I)oxide, as well as carriers and/or other additives, the ratio of component A to component B being preferably from about 1:0.1-3.
Claims9
A fungicidal composition comprising a synergistic fungicidally effective amount of the mixture of
- (a) propyl 3-(dimethylamino)propylcarbamate or an acid addition salt thereof, and
- (b) a compound selected from the group consisting of zinc propylenebis(dithiocarbamate) (propineb). zinc ethylenebis(dithiocarbamate) (zineb), manganese ethylenebis(dithiocarbamate) (maneb) zinc ammoniate ethylenebis(dithiocarbamate)-poly(ethylenethiuramdisulphide) (metiram), and a carrier, wherein the ratio of component A to component B is from about 1:01.1 to 3.
A method of combating a fungus which comprises applying to the fungus or its locus a synergistic fungicidally effective amount of a mixture of
- (a) propyl 3-(dimethylamino)propylcarbamate or an acid addition salt thereof, and
- (b) a compound selected from the group consisting of zinc propylenebis(dithiocarbamate) polymer (propineb). zinc ethylenebis(dithiocarbamate) polymer (zineb). manganese ethylenebis(dithiocarbamate)-poly(ethylenethiuramdisulphide) zinc ammoniate (metiram), wherein the ratio of component A to component B is from about 1.0.1 to 3.
