Looking at my early-planted fields I am seeing weeds starting to emerge even with the “stronger” soil-applied treatments. Even with the best soil-applied herbicide programs, we expect to see weed breaks.
In addition, we are starting to see warmer days and weeds are going to be growing faster than during cooler weather. Weed will be reaching 3 to 4 inches sooner than had they emerged in early May.
Finally, the early planted corn is developing a canopy that can interfere with spray coverage.
Don’t get caught off-guard, be sure to scout these fields and devise a solid approach for your “next step”.
