Sunnhemp’s allelochemical effect may be a useful attribute for weed
management in sustainable production systems.However, plant growth in the field in crops
such as bell pepper, tomato, onion, and turnip may be impacted as a result of allelopathic
activity of sunnhemp residues. Thus, weed management may be more effective when
sunnhempis grown in rotationwith crops that tolerate the allelochemicals fromsunnhemp,
resulting in optimization of the rotation effects.
