Abstract
The bioherbicidal fungus, Colletotrichum truncatum (Schwein.) Andrus & Moore, was tested at different inoculum concentrations alone and in combination with, prior to or following treatment with different rates of glyphosate ( N ‐[phosphonomethyl]glycine) (Roundup Ultra) for the control of hemp sesbania ( Sesbania exaltata [Raf.] Rydb. ex A.W. Hill) in Roundup Ready soybean field plots. Colletotrichum truncatum and glyphosate were applied in all pair‐wise combinations of 0, 1.25, 2.5, 5.0, and 10.0 × 10 6 spores mL −1 (i.e. 3.125, 6.25, 12.5, and 25 × 10 11 spores ha −1 ), and 0.15, 0.30, 0.60, and 1.2 kg ha −1 , respectively. Weed control and disease incidence were enhanced at the two lowest fungal and herbicidal rates when the fungal spores were applied after glyphosate treatment. The application of the fungus in combination with or prior to glyphosate application at 0.30 kg ha −1 resulted in reduced disease incidence and weed control regardless of the inoculum's concentration. At the highest glyphosate rates, the weeds were controlled by the herbicide alone. These results suggest that it might be possible to utilize additive or synergistic herbicide and pathogen interactions to enhance hemp sesbania control.
