Screening of Preemergence and Postemergence Herbicides for Weed Control in Dill (Anethum graveolens), Fennel (Foeniculum vulgare), Coriander (Coriandrum sativum), and Basil (Ocimum basilicum)

One of the limiting factors in aromatic crop production in Canada and in the United States is the lack of registered herbicides for weed control. Greenhouse experiments were conducted to screen 30 postemergent and five preemergent herbicides for weed control in the aromatic crops dill, coriander, basil, and fennel. Our results suggested that the following herbicides could be used for weed control in the four crops: pyridate, linuron, trifluralin and pendimethalin in dill, sethoxadim, isoxaben, linuron, trifluralin and pendimethalin in coriander, sethoxadim, fluzifop-p-butyl and propyzamide in basil, and ethofumesate, fluzifop-p-butyl, sethoxidim, linuron, trifluralin and pendimethalin in fennel.
