Evaluation of Wood Vinegar as an Herbicide for Weed Control

Wood vinegar, a by-product of wood pyrolysis, is mostly discarded. vinegar has phytotoxic effect and could be potentially used as naturally derived herbicide for weed control. The objective this research was to evaluate the efficacy from pyrolysis apple (Malus × domestica Borkh.) tree branch wastes control weeds. concentrations required inhibit 50% motherwort (Leonurus cardiaca L.), redroot pigweed (Amaranthus retroflexus Spanish needles (Bidens pilosa tall fescue (Festuca arundinacea L.) seed germination measured 0.51%, 0.48%, 0.16%, 1.1%, respectively. application rates (spray volume) provide 1911 L ha−1 653 ha−1, respectively, while highest evaluated rate at 4000 controlled 35% by 10 days after treatment (DAT). Common purslane (Portulaca oleracea increased 500 2000 ha−1. more effective in dark than light conditions controlling common purslane. By 5 DAT, averaged over rates, provided 95% 87% conditions, These findings suggest that obtained branches management.
