Heavy Weed Pressure Shows Value
If there’s one thing heavy weed pressure can do, it’s show the value of a residual herbicide. Earlier this summer, colleagues visited with Minnesota corn growers who started the season off well by averting planting delays seen by much of the Midwest. Due to a colder than normal spring, lambsquarters had not yet germinated when growers cultivated their fields, which left thousands of seeds to take root alongside the crop.
Growers who incorporated a residual herbicide into their program saw fewer lambsquarters problems, as well as fewer issues with other prevalent weeds such as waterhemp and ragweed. Shortly after my colleague visited, growers and retailers experienced a week of above average temperatures and rain. And, corn rapidly grew toward canopy leaving growers who used residual herbicides satisfied with the length of weed control encountered.
Can you tell the difference in fields that saw a residual application and those that only received a glyphosate treatment? To what extent do you think it will affect yields?
