Abstract
Mixtures of certain triazole fungicides (component I) and 4-cyclopropyl-6-methyl-N-phenyl-2-pyrimidinamine (component II) have a synergistically increased activity against fungus infestation. Components I and II can also be applied to crops individually in immediate succession.
Claims4
A synergistic, fungicidal, two-component composition, having an effective amount of an ergosterin-biosynthesis inhibitor of the triazole series as component I and a 2-anilinopyrimidine derivative as component II, wherein component I is 4-(4-chlorophenyl)-2-phenyl-2-(1,2,4-triazol-1-ylmethyl)-butyronitrile or a salt or metal complex thereof, and component II is 4-cyclopropyl-6-methyl-N-phenyl-2-pyrimidinamine of the formula ##STR2## or a salt or metal complex thereof, wherein the synergistic weight ratio of component I to component II is in the range of 2:1 to 1:20, together with a carrier.
A method of controlling fungi, which comprises treating a locus infested with, or liable to be infested with, fungi with an effective amount of an ergosterin-biosynthesis inhibitor of the triazole series as component I and a synergistically effective amount of a 2-anilinopyrimidine derivative as component II, in either sequence or simultaneously, wherein component I is 4-(4-chlorophenyl)-2-phenyl-2-(1,2,4-triazol-1-ylmethyl)-butyronitrile or a salt or metal complex thereof, and component II is 4-cyclopropyl-6-methyl-N-phenyl-2-pyrimidinamine of the formula ##STR3## or a salt or metal complex thereof, wherein the synergistic weight ratio of component I to component II is in the range of 2:1 to 1:20.
