HERBICIDE CLASSIFICATION - Purdue University

1 HERBICIDE . CLASSIFICATION . REPEATED USE OF HERBICIDES WITH THE SAME SITE. OF ACTION CAN RESULT IN THE DEVELOPMENT. OF HERBICIDE -RESISTANT WEED POPULATIONS. MODE OF. by PREMIX. This chart groups herbicides by their modes of action to assist you This chart lists premix herbicides alphabetically by their trade by ACTION in selecting herbicides 1) to maintain greater diversity in HERBICIDE use and 2) to rotate among effective herbicides with different sites names so you can identify the premix's component herbicides and their respective site-of-action groups. Refer to the Site- (effect on plant growth) of action to delay the development of HERBICIDE resistance.
