Interpretive Summary:

Technical Abstract: Weeds present in peppermint and spearmint reduce mint oil yield and quality. Flumioxazin combinations with clomazone and pendimethalin 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.
