Field experiment conducted at the Crop Research Centre of G.B. Pant University of Agriculture and Technology, Pantnagar during 1985 and 1986 revealed that unrestricted weed growth reduced the herbage and oil yields of Japanese mint by 86.6 and 87.8%. respectively. Pendimethalin at 1.5 and oxyfluorfen at 0.3 kg/ha as pre-eme. application recorded the highest weed control efficiency and also produced the green herbage, oil and menthol yield compared to the yield of weed free treatment. Fluchloralin as preplant soil incorporation was toxic to mint crop. mint oil.
