Technical Abstract: Weeds present in peppermint and spearmint reduce mint oil yield and quality. Mustard seed meal applied at 1 and 2 ton/acre to newly planted peppermint reduced annual weed emergence for several weeks without injuring peppermint. Field pennycress seed meal applied at similar rates did not suppress weeds. Flumioxazin alone or in combinations with clomazone, pendimethalin, or terbacil applied to dormant peppermint controlled prickly lettuce and flixweed without significant injury to the crop. Low rates of flumioxazin and sulfentrazone applied immediately after the first cutting of hay and prior to mint regrowth, controlled redroot pigweed with minimal peppermint injury. Fluroxypyr controlled prickly lettuce well in peppermint when applied alone, but activity on prickly lettuce was reduced in tank mixtures with bromoxynil. Bromoxynil tank mixed with fluroxypyr improved control of common groundsel and flixweed compared to fluroxypyr alone.
