Make the “wait and see” approach to weed control work

Your agronomist, retailer, consultant, crop insurance rep and many others likely recommend planning ahead for next season. And that’s good advice.  But it isn't always possible, especially since the weather is so unpredictable.

If you are more of a “wait-and-see” manager, you can still make at least your weed control program work. If you prefer to “wait and see” what shows up in your field before spraying, start with a pre-emerge residual herbicide.  Even with limited time this spring, it can be worth the effort.
Pre-emergence residual herbicides make choosing between and 1-pass and 2-pass herbicide system a realistic possibility. With early season weeds out of the way, you can scout to see if a second application is needed. Even university weed scientists note that good pre-emerge programs can sometimes eliminate the need for additional post applications.
Note that whatever your approach to this late spring, you should probably still give your crop protection dealer a heads-up, so they are prepared to “wait and see” with you.
