Tropical spider wort now a reality in S. Mississippi

Tropical spider wort - AKA Benghal dayflower - was identified this year in 6 cotton and 4 peanut counties in George and Jackson Counties in south Mississippi, according to a report in this month's Agronomy Notes, published by the Miss. State University Cooperative Extension Service. Weed scientist John Byrd reported that it also had turned up in one field of ryegrass.

This weed - which can be annual or perennial - has been a tough customer in parts of Alabama, Florida and Georgia, particularly where growers rely heavily on glyphosate-resistant crops.
