Dr. Joseph C. Neal —
IXth International Bioherbicide Group Workshop
The IXth International Bioherbicide Group (IBG) Workshop on February 8, 2009, was conducted as a satellite conference of the Weed Science Society of America (WSSA) / Southern Weed Science Society (SWSS) joint meeting in Orlando, FL. We hope that conducting this workshop in conjunction with the WSSA annual meeting facilitated the exchange of information among biological control researchers and “traditional” weed scientists; and fostered a greater understanding of the role biological control may play in weed management systems for agroecosystems and public lands. The workshop was facilitated and supported by a conference grant from the US Department of Agriculture.
In addition to the volunteer presentations at the IBG workshop, a field tour of weed biocontrol sites Monday February 9th was organized by Dr. Jim Cuda of the University of Florida and the local Cooperative Extension staff. Tuesday February 10th the WSSA sponsored symposium: "Plant Pathogens and Biological Control of Weeds: A Symposium in Honor of Dr. R. Charudattan" was a huge success.
Abstracts and Papers
Abstracts submitted through the WSSA on-line registration system are published in the on-line WSSA abstracts. Printed copies of the IBG Workshop Proceedings were distributed at the workshop. An pdf version of the proceedings is avaliable through this link.
