September 16, 2004 - new software program, the “Interactive Encyclopedia of North American Weeds” may be of interest to you.  It offers more than 2,400 photographs covering 447 of the most important weeds and crops in the United States and Canada. The illustrated glossary of 565 botanical terms is a program in itself!  A unique illustrated interactive identification key now covers all of the weeds in the program. The professionally narrated lessons provide nearly three hours of interactive instruction on the basics of plant taxonomy needed to identify plants.

After 12 years of development, the program provides a balanced and fully integrated teaching and reference resource for weed, crop, and plant identification. The DVD is an excellent resource for teaching plant taxonomy and weed identification courses, basic botany, agronomy, and horticulture courses, and high school biology and vocational agriculture courses. A presentation maker feature allows an instructor or presenter to create a custom path through the program. Professional agronomists, horticulturalists, grounds keepers, landscapers, turf managers, gardeners, herbalists, botanists, and all manner of plant enthusiasts will enjoy the extensive descriptions, distribution maps, habitat key, World of Weeds weed history articles, and the unique visual weed and crop identification key.
