Abstract
Methods and products for inhibiting growth of fungus and fungal disease on a plant. Methods comprise contacting at least a portion of a plant or plant seed together with a fungicidal composition comprising a fungicidal carboxamide. Products comprise any of leaves, crowns, roots, stolons, seed, seedlings, sod, and any combination thereof, treated with a fungicidal carboxamide. Preferred pathogens are of the genus Colletotrichum, preferred disease is anthracnose, preferred fungicides are carboxamides, and preferred plants are turfgrass.
