Common Chinese herbal herbicides can prevent and control annual gramineous weeds, broadleaf weeds, Cyperaceae weeds and some perennial weeds in Chinese herbal medicine fields of Umbelliferae such as Radix Isatidis, Rhizoma Coptidis and Radix Angelicae Dahuricae. Herbicides are absorbed and transmitted to the roots of plants through stems and leaves, and the weeds are inhibited from dying due to photosynthesis.
In general:
The best release effect is in the 3-5 leaf stage of weeds. It is especially suitable for weeding Umbelliferae medicinal fields with high planting density and difficult manual weeding, saving time and labor.
