This recently revised guide is a 5.5" x 8.5", 164 page spiral bound book printed in color. The guide covers 75 plants species, including 60 broadleaf and 15 grass species. For each species the guide includes a photo of the cotyledon leaves, first true leaves, rosettes (where applicable), mature plants, and seeds.
Symbols in the upper left indicate whether the plant is primarily a weed of cropland or rangeland. Cotyledon leaf shape icons along with colored bars separate species by cotyledon shape (forbs) and ligule characteristics (grasses). An introduction covers basic tenets of weed management and how weed seedling identification is essential to a successful weed management program.
