Today, it’s not nearly as simple to achieve adequate weed control in soybeans as it was 10 years ago. Weeds have evolved and herbicide resistance has created some considerable challenges over time. Below are a few reminders of management practices you might consider with your specific soybean technology.

Herbicide with Fungicide & Insecticide?
Many times when discussing post herbicide programs with farmers, we get the question, “Can I apply my fungicide at the same time as I apply my post herbicide?” Ensuring successful weed control must be our top priority. A dead weed will not produce viable, resistant seed. So optimal timing of our post herbicide should be dictated by weed pressure and weed height. In most all situations, a post herbicide treatment will be needed prior to the R3 growth stage. If you remember back to our PFR Insight Meetings in January, we shared the results of our fungicide and insecticide timing study with you. As you can see below, timing is everything. With commodity prices as they are today, it is critical to get our fungicide and insecticide applied at the R3 growth stage to be profitable with this input. Not only is timing critical, but the correct nozzle to produce finer droplets and the correct gal./A. are also important components to a positive ROI with a fungicide application. So in most cases, all the stars will not align to make this into a single application without making a sacrifice to either weed control or disease management.
R3 growth stage: 3/16 in. pod on any of the top four nodes on the main stem.
