Abstract

Practical herbicides are classified into several groups according to their mode of action by the Herbicide Resistance Action Committee (HRAC) in cooperation with the Weed Science Society of America (WSSA). The actual classification is composed of 15 groups with 9 subgroups and currently contains a total of 269 kinds of herbicides. Chapters 1–8 deal with representative herbicides belonging to 8 HRAC groups; B (acetolactate synthase inhibitors), F1—F3 (carotenoid biosynthesis inhibitors), G (EPSP synthase inhibitors), H (glutamine synthetase inhibitors), A (ACCase inhibitors), K3 (very long-chain fatty acid, VLCFAs biosynthesis inhibitors), L (cellulose biosynthesis inhibitors) and E (protoporphyrinogen-IX oxidase, PPO inhibitors). Each group contains 50, 19, 2, 2,16, 21, 4 and 26 kinds of practical herbicides, respectively. This chapter briefly summarizes agrochemical characteristics and major synthetic routes for these modern herbicides and chronologically reviews the structural evolution of related compounds (more than 900) disclosed since 1990 except for the PPO inhibitors since 1995.
