Perennial Weeds: Characteristics and Identification of Selected Herbaceous Species

For the student, instructor, or practitioner dealing with perennial weeds on a daily basis, this work uses 28 weed species to illustrate the ways in which perennial weeds propagate vegetatively. The author has taken care to use examples of perennial weeds that are troublesome on a national scale, or representative of principal agricultural regions within the United States and Canada. Using both tables and text to assist the reader in identifying each weed species, the book includes 67 illustrations that highlight reproduction, over-wintering, and perennating parts. It also corrects some misconceptions in the weed science literature as to whether the perennating organ is a root or a rhizome. Not just another identification guidebook, Perennial Weeds takes the reader through root systems and rhizome anatomy to discuss exactly how perennial weeds propagate, so that eradication can be achieved in the most environmentally sound ways. It emphasises why perennial weeds are so difficult to control and offers suggestions for their control.
