In the era of increasing weed resistance to herbicides, establishing a successful weed management program is crucial to every growing season. However, for this management program to be successful, growers must identify the adversary in the field. Doing so, will help them tailor their program to target specific weeds.
But, accurately pinpointing damaging weeds can be problematic as some weeds can easily be mistaken for one other. When simple identification mistakes are made, the result can lead to incorrect management decisions and potential yield loss.
An ally in weed identification
To help growers classify the enemy in their field, BASF has developed a series of weed identification videos. The videos outline subtle, yet important details in diagnosing broadleaf and grass weed issues on any operation.

Chad Brommer, technical market manager for herbicides with BASF, offers tips growers can use to help lead to cleaner fields. He also emphasizes the importance of correct weed identification. "Putting identification knowledge to the test by scouting early and often can build a strong weed control program for growers," he says.
Spotting fugitive weeds in your field
Two aggressive weeds that can often be misidentified are waterhemp and Palmer amaranth. As both are in the amaranthus family, waterhemp and Palmer amaranth have the potential to grow up to 2 inches per day, putting a lot of pressure on growers to implement quick, effective weed control solutions.
Both weeds have substantial visual similarities, but as Brommer explains, knowing to look for subtle, yet significant features can go a long way to correct identification.
"Recognizing key characteristics like leaf shape, color and finish will help distinguish weeds from one another and lead to an effective management strategy for the growing season," he says.

Are you confident you know the best ways to prepare your sprayer for the season ahead? Are you sure you know the best practices for minimizing herbicide spray drift? Read through these best practices to make sure you are on the right track.
Brommer also notes that the same weed species will often show up in a field year after year, meaning truly understanding your land and paying attention to trends can certainly benefit growers in weed identification. Once weeds are properly identified, growers can adjust their weed management program to specific targets, helping enhance the effectiveness of weed control, he says.
