SW Iowa | Iowa State Extension has a free weed guide pdf with info on herbicide premixes (a lot of common products are a combination of 2 or more actives). I think other states have similar resources.
If I see something being discussed I'm not familiar with I'll often just look up a label on CDMS ( http://www.cdms.net/LabelsSDS/home ) -- actives are listed on the label as a legal requirement, and it usually only takes an online search or two to figure out what something is or has common ingredients with. | |
