C. Comm<strong>on</strong> and chemical names of herbicides<br />
Chemical names of herbicides vary, depend<strong>in</strong>g <strong>on</strong> the standard adopted. The comm<strong>on</strong> standards are<br />
CHEMICAL ABSTRACTS (CA) and Internati<strong>on</strong>al Uni<strong>on</strong> of Pure and Applied Chemistry (IUPAC). When<br />
possible. this handbook used CA (which is also followed by the <strong>Weed</strong> Science Society of America).<br />
