Recent developments - including an increased usage of low-till crop systems; environmental concerns; and the need for better weed control - have all combined to create a need for a revision of the text. This edition brings the previous text up to date with current principles and practices.

Also included are guidelines on weed--control practices for specific crops or situations, such as small grains, row crops, horticultural crops, lawns and turf, range land, brush, and aquatic plant life. Generously supplemented with 300 drawings, photographs, and tables, Weed Science is an essential book for students taking an introductory course in weed science, as well as a reference for agricultural advisors, county agents, extension specialists, and professionals throughout the agrochemical industry.
