Tropical Spiderwort:Every now and then, this weed emerges to remind producers it can be quite a formidable foe

摘要

Tropical spiderwort, also called Benghal dayflower, is a weed that came on the row-crop production scene in the early 1990s and continues to crop up from time to time. Although Palmer amaranth became the weed garnering most of the attention in. the last decade, tropical spiderwort never really went away. As production schemes change, and different herbicide regimes are used, producers will find this weed popping back up in their fields and commanding attention. Because of this, University of GeorgiaExtension weed specialist Eric Prostko continues to conduct research on management of this weed.
