A plant-microbicidal composition having synergistic action, comprising at least two active ingredient components, wherein component I is a compound selected from the group (IA) 1-[3-(2-chlorophenyl)-2-(4-fluorophenyl)oxiran-2-ylmethyl]-1H-1,2,4-triazole (“epoxiconazol”); (IB) 4-(4-chlorophenyl)-2-phenyl-2-(1,2,4-triazol-1-ylmethyl)-butyronitrile (“fenbuconazol”); (IC) 5-(4-chlorobenzyl)-2,2-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)-cyclopentanol (“metconazol”); (ID) 2-(2,4-dichlorophenyl)-3-(1H-1,2,4-triazol-1-yl)propyl-1,1,2,2-tetrafluoroethyl ether (“tetraconazol”); (IE) α-[2-(4-chlorophenyl)ethyl]-α-(1,1-dimethylethyl)-1H-1,2,4-triazole-1-ethanol (“tebuconazol”); (IF) 1-[4-bromo-2-(2,4-dichlorophenyl)tetrahydrofurfuryl]-1H-1,2,4-triazole (“bromuconazol”); or in each case one of the salts or metal complexes thereof; and component II is (IIA) 1-[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-ylmethyl]-1H-1,2,4-triazole (“propiconazol”) and/or (IIB) 4-cyclopropyl-6-methyl-N-phenyl-2-pyrimidineamine (“cyprodinil”), or in each case one of the salts or metal complexes thereof.
A plant microbicidal composition comprising at least two active ingredient components being component I and component II in a synergistically effective amount, together with an inert carrier, wherein said component I is metconazol or a salt or metal complex thereof, and said component II is propiconazol or a salt or metal complex thereof, wherein the weight ratio of component I to component II is in the range of about 1:10 to about 10:1.
A method of controlling and preventing the occurrence of fungi on plants, which comprises treating a site infested by or threatened with infestation by fungi with a fungicidally effective amount of a component I which is metconazol or a salt or metal complex thereof, and a component II which is propiconazol or a salt or metal complex thereof, wherein the weight ratio of component I to component II is in the range of about 1:10 to about 10:1, in any desired order or simultaneously.
