Resources for weed identification

Herbicide/Weed Database

The Herbicide/Weed database is an interactive tool to assist in herbicide selection.  Users can select from multiple options, such as crop type and weed species, to determine which herbicides could help with their particular weed control needs.

This database is intended to be a resource for choosing herbicides: it is not a replacement for any information contained on labels.  Always check product labels before applying herbicides to any crop.

The database can be accessed at: https://herbicides.hrt.msu.edu
