Manage Weeds Before They Thrive

Jun 13, 2022


Smaller waterhemp plants are manageable while larger plants get out of control.
Crop’s in. Weeds are growing. Time to scout and make sure your pre- and post-emerge herbicide applications are done on time.
 
Some growers may still be working on their pre-emerge spraying, but for those further down the road, “don’t let the weeds get more than 2-3 inches tall, 4 inches at most,” said Craig Loen, Federated agronomist at the Osceola location.
 
Remember that it’s easier to kill a weed with only one growing point than a weed that has taken off with 15-20 growing points. Once the weed canopies are established, herbicides can’t get down to the newer growing points on the lower parts of weed stems. And on the likes of waterhemp, those stems can be like young “trees” – very hard to kill, Loen described.
 
Get your post-emerge spraying done on time – within 28 days of the pre-merge herbicide application. Mark the dates on your calendar. If you planted on Thursday, four Thursdays later is the end of your spraying window, Loen noted.
 
“Get on Federated’s list [for custom application] and communicate with us,” he said. Let us know what kind of corn or what kind of beans you planted, and what sensitive areas are near your fields,” said Loen. Communication is critical for safe and timely applications.
