Control and translocation of saflufenacil in fleabane (Conyza spp.) according to plant integrity

Efficient herbicide absorption and translocation, satisfactory weed control can be affected by the site of application. However, during harvesting crops previous soybean sowing, cutting process made harvesters on fleabane may generate a difficult management in pre sowing crop limiting leaf area herbicide. Experiments were conducted to evaluate efficiency translocation potential saflufenacil plants with different stem conditions. Experiment I was arranged 2x10 factorial scheme, factor A corresponding integrity, B levels injury Weed evaluated at 7, 14, 21 days after treatment (DAT), dry matter DAT. II consisted applying structures, where percentage necrotic 1, 3, 5, 7 Fleabane higher than 75% all treatments application, greater previously defoliated. Saflufenacil application 10 20 cm hairy also efficient treatments. old showed larger area, while resulted lower area. The main pathway for is via xylem proved element when limited.
