This database was created by Dr. Bernard Zandstra in the Department of Horticulture at Michigan State University. It contains data from Dr. Zandstra's herbicide research program, peer-reviewed research articles, and product labels. The database will be updated regularly as new herbicide label information is available.

For questions about herbicide efficacy, crop-specific herbicide recommendations, or other herbicide related inquiries, contact Dr. Zandstra at zandstra.msu.edu or 517-353-6637.

To report missing or incorrect data or for issues accessing or using the database, please contact one of Dr. Zandstra's technicians: Colin Phillippo at phill394@msu.edu or Monique Hemker at hemkermo@msu.edu
