Interpretive Summary: Technical Abstract: Tropical spiderwort (also known as Benghal dayflower) has gone from relative obscurity as a roadside curiosity to troublesome weed with widespread economic impact in Georgia in less than 10 years. South Georgia and Florida are currently plagued by tropical spiderwort, but isolated populations have been discovered in Alabama, South Carolina, and North Carolina. A weed in warm temperate regions throughout the world, tropical spiderwort has recently invaded US cropping systems in response to significant recent changes in cropping systems. These changes include, but are not limited to, elimination of the use of PRE herbicides with soil residual activity in cotton, adoption of reduced tillage (coupled with elimination of cultivation as a weed control tactic), reliance on glyphosate-based systems in cotton, and a large increase in cotton acreage in Georgia. Peanut is one of the crops in which tropical spiderwort can be effectively managed with many herbicides, including s-metolachlor, gramoxone, impazapic, and imazethapyr. The purpose of this symposium is to share the latest research on this troublesome weed within the southeast region. Tropical spiderwort research is truly a regional effort, as evidenced by the affiliations of the various presenters, to rapidly increase our knowledge of this weed. |
