Abstract
Chiral fungicides and compositions containing the same are provided. Also provided are methods for using the compositions of the present invention for inhibiting the growth of fungi, including phytotoxic fungi. The use of a single isomer in treating particular plant species and against particular fungi allows for selective inhibition of fungal growth with reduced fungicidal phytotoxic effects.
Claims11
A method for inhibiting the growth of fungus in association with a plant comprising applying to the locus of a plant a fungicidally effective amount of the (S)-enantiomer of 1-[2-(2,4-dichlorophenyl)-2-(2-propenyloxy)ethyl]-1H-imidazole, substantially free of the (R)-enantiomer.
A fungicidal composition comprising a fungicidally effective amount of the (S)-enantiomer of 1-[2-(2,4-dichlorophenyl)-2-(2-propenyloxy)ethyl]-1H-imidazole, substantially free of the (R)-enantiomer, and an agriculturally acceptable carrier.
A fungicidal composition comprising a fungicidally effective amount of 1-[2-(2,4-dichlorophenyl)-2-(2-propenyloxy)ethyl]-1H-imidazole enriched in the (S) enantiomer wherein the enrichment is at least 70 mol percent.
A fungicidal composition comprising a fungicidally effective amount of 1-[2-(2,4-dichlorophenyl)-2-(2-propenyloxy)ethyl]-1H-imidazole, said imidazole being enriched in the (S) enantiomer, wherein the enrichment is at least 70 mol percent and an agriculturally acceptable carrier.
