Kenley I ABSTRACT The 16 1h annualNortheastWeedScience Societycollegiateweed contestwas held on July20, 1999 in Blacksburg, Virginia, on the campus of Virginia Polytechnic Institute and State University and the nearbySmithfieldPlantation. A total of 57 studentsfrom 10 universities competed in the contest, which was an 8-hour event that began at 8:00 a.m. and lasted until 5:00 p.m. Schools competing in the contest included Cornell University, North Carolina State University, Penn State University, State University of New York - Cobleskill, University of Delaware, University of Guelph, University of Kentucky, University of Maryland, University of Nova ScotiaAgriculturalCollege.andVirginiaPolytechnicInstituteandStateUniversity. There were a total of 9 graduate and 9 undergraduate teams along with 2 graduate individuals and I undergraduateindividualcompetingin thecontest. Contestants tested their skills in weed identification, herbicide symptomology, sprayer calibration, and solving grower problems throughout the course of the day. Students were requiredto identify 20 weeds by common name and 5 weeds by scientific name in the weed identificationevent,and 10 unknownherbicidesin the herbicidesymptomologyevent. Threeof the growerproblemsin this year's contestwere associatedwith turfgrass,one probleminvolved pumpkinproduction,andthe remainingthreeproblemswere associatedwith com production. North Carolina State University (Shawn Askew, George Scott, Andrew McRae coached by John WHcut), finished first in the graduate contest, while Virginia Polytechnic Institute and State University (Rob Richardson, Peter Sforza, Andy Bailey, Greg Armel, coached by Dan Poston) finished second. Penn State University (Wade Esbenshade, Steve Josimovich, coached by Dwight Lingenfelter) finished third place in the contest. The first place graduate individual in the contest was Rob Richardson from Virginia Polytechnic Institute and State University. Second place in the graduate individuals went to Shawn Askew from North Carolina State University, while third place went to Art Graves from Virginia Polytechnic Institute and State University. George Scott andAndrew McRae, both from North Carolina State University, tied for fourth place. The winner of the undergraduate contest was Nova Scotia Agricultural College (Kerry Cluney, Gordon Murray, Peter Burgess, Stephen Crozier, coached by Glen Sampson), followed by State University of New York - Cobleskill (Steven DuBois, Andrew Miller, coached by Doug Goodale) in second place andNorthCarolinaStateUniversity(Kevin Clemmer,John Lowery.

VIRGINIA TECH'S ONLINE WEED IDENTIFICA nON AND PEST MANAGEMENT GUIDE K. W. Bradley, P. Sforza, and E. S. Hagood I ABSTRACT The Virginia Tech Weed Identification Guide and the Pest Management Guide for Field Crops have been available on the internet since 1996 at the web sites http://www.ppws.vt.edu/weedindex.htm and http://www.ppws.vt.edu/-pmg/intro.htm. Collectively, these guides serve as an important resource for many growers and agrochemical dealers throughout Virginia and the eastern United States. More recently, the weed identification guide has developed into a valuable educational resource in undergraduate weed science courses taught at Virginia Tech and at other universities across the nation. The weed identification guide currently has 180 separate weed species available for viewing, however additional weed images are being added daily. Each web page provides an average of 3 to 4 images of each weed. These images illustrate specific features of each weed that are important for identification, such as flowers, fruit, and leaf shape. Many of the weed pages have a botanical description accompanying each image and additional descriptions will be included in the future. The weed identification guide is primarily intended to assist in the identification of common weeds and weed seedlings that normally occur in most pastures and field crops of the eastern United States. However, several aquatic weeds and weeds commonly associated with turfgrass are also included in the guide. The online pest management guide contains current weed control recommendations for alfalfa, com, cotton, pastures, small grains, sorghum, soybeans, peanuts, and tobacco. The recommendations included in the guide are based on research conducted by several extension weed specialists at Virginia Tech and throughout the northeastern United States. Recommendations are given for some of the more common and troublesome weeds associated with each crop, along with specific use-rates for each herbicide listed. The web pages also contain a guide to prepackaged herbicide mixtures, a guide to single active ingredient herbicides, and rainfree periods for most postemergence herbicides. The internet guide is updated regularly and is a direct reflection of the information published in the annual Virginia Cooperative Extension Pest Management Guide for Field Crops. 'Grad. Res.
