Identifying weed species is the most important factor in developing an effective weed control program for corn and cotton crops.

Understanding the weed population in a crop gives a producer information necessary to select the proper herbicide, the right rate and the correct application timing, said Matt Matocha, AgriLife Extension program specialist—weed science, College Station.

A recent field day at the Texas A&M University field laboratory near College Station showcased the latest strategies in managing problem weeds in corn and cotton. The lab serves as a research and teaching platform for Texas A&M AgriLife.

The field day was sponsored by BASF Corp. and the Texas A&M AgriLife Extension Service.
