Click on diagram to enlarge. It also has been contended that some herbicides, particularly atrazine, have specific mechanisms of action in aquatic frogs and fish, including developmental abnormalities (Hayes et al. This publication provides herbicide mode of action, group number, site of action, chemical family, active ingredient, and example trade names for herbicides currently registered in Wisconsin. PDF/X-1:2001 This narrative generally follows the diagram top to bottom, left to right. startxref They are fast acting: effects on foliage are visible within minutes of application. Sources associated with urban development (e.g., stormwater runoff) and industry (e.g., herbicide manufacturing plants) may discharge effluents containing herbicides into streams. The site navigation utilizes arrow, enter, escape, and space bar key commands. It is therefore important to be aware of weed resistance in your field and region, and develop a strong management program containing multiple effective herbicide sites of action.
