Emerged weeds have the potential to reduce crop yield. Agronomists and weed scientists recommend using more soil residual herbicides at full use rates to take weed stress off non-residual postemergence herbicides by introducing multiple, effective modes of action, different chemistries and controlling weeds for longer periods of time before they emerge. This strategy is called the Overlap System....More

If wet weather has delayed postemergence herbicide application to your soybean fields, there may be some large giant ragweed that needs treating. Mark Loux, Ohio State University, offers tips for herbicide application, depending on resistance levels....More
This installment of 5 ag stories to read offers tips on assessing early-planted corn hail damage. Consider global fertilizer outlook and Chinese purchase of soybeans, as well as pesticide use in U.S. agriculture for the past five decades. And, have a little fun with a new soybean meme!...More
The USDA Economic Research Service released finding from a pesticide use study. Over the last five decades, pesticide use on corn, soybeans and other crops, as well as active ingredients, has changed dramatically in U.S. agriculture, including herbicide and insecticide use.
Wet or windy conditions may have kept farmers from applying a preemergence herbicide this spring. However, Bill Johnson and Travis Legleiter, experts from Purdue Extension say that many of these herbicides are still safe for farmers to use after corn has emerged so long as they pay close attention to product selection and application timing....More

Due to late planting, and then wet, cool weather last week, some farmers were unable to apply a pre-emergence herbicide to corn. The University of Nebraska-Lincoln has some tips for applying a residual herbicide after corn emergence, including reminding growers to not apply herbicide with nitrogen, There is also a chart with corn stages, weed growth and the appropriate herbicides to apply....More
A recent trial by the University of Minnesota showed that using a preemergence (pre) herbicide in soybeans is beneficial, offering a significant reduction in weed densities early in the season. Weed escapes at the end of the season were nearly eliminated when using a pre herbicide, as well....More
