Over the last two seasons we have conducted field trials that have examined the economics of commercial weed control programs in corn and soybeans that are currently being marketed to Michigan growers.

These studies compared weed control, crop injury, yield, and the economic returns of dominant weed control programs being marketed to Michigan growers. Each major herbicide company was asked to submit up to four weed control programs for these studies based on soil type and weed infestation history at each site. Results comparing the different weed control programs are now available online as a pdf at the CAT Alert web site at:
