Abstract
The invention relates to plant protection compositions based on a two-component system of plant fungicides, one of which is 1-[2-(2,4-dichlorophenyl)pentyl]-1H-1,2,4-triazole and the other is Mancozeb, which is an [ethylenebis(dithiocarbamato)]manganese complex with [ethylene-bis(dithiocarbamato)]zinc of the formula II ##STR1## In the range from 1:3 to 1:100 the disclosed mixtures display enhanced fungicidal activities.
Claims5
A composition for controlling fungal diseases in agriculture and horticulture comprising a fungicidally effective amount of an admixture of:
- (a) 1-[2-(2,4-dichlorophenyl)pentyl]-1H-1,2,4,-triazole (compound I) and (b) an [ethylenebis(dithiocarbamato)]manganese complex with [ethylenebis(dithiocarbamato)]zinc of the formula II:
- ##STR4## the weight ratio of said compound I to said compound II being from 1:3 to 1:100, in combination with a solid or liquid carrier, wherein the amount of compound I is sufficient to potentiate the fungicidal activity of said complex.
A method of controlling fungal diseases in agriculture and horticulture which comprises applying to the plants or their locus a fungicidally effective amount of a mixture of:
- (a) 1-[2-(2,4-dichlorophenyl)pentyl]-1H-1,2,4,-triazole (compound I) and
- (b) an [ethylenebis(dithiocarbamato)]manganese complex with [ethylenebis(dithiocarbamato)]zinc of the formula II:
- ##STR5## the weight ratio of said compound I to said compound II in the mixture being from 1:3 to 1:300, in combination with a solid or liquid carrier, wherein the amount of compound I is sufficient to potentiate the fungicidal activity of said complex.
