Hemp exhibited high level of sensitivity to most of the tested herbicides. Visual injury levels ranged from almost no injury (~5%) with only one herbicide, to some temporary injury (~20%) with a few herbicides and severe injury or death (60%-93%) with about 10 out of 18 herbicides tested.
Hemp exhibited relatively good tolerance to several products that can be used postemergence in industrial hemp. It is important to note that the conclusions are based only on one year of data. This study will be repeated in 2021 season.
