The last few irrigations of the growing season are important management decisions to ensure a successful crop without wasting resources. Many growers think of Labor Day as the unofficial end of the irrigation season, but will that leave us with enough moisture in the root zone to carry the crop to maturity? Assuming we won’t get any help from Mother Nature or have an adequate irrigation water supply, here are a few factors to consider when planning your final watering.

Most of the management of a corn crop is completed during the first half of the growing season. Establishing a consistent stand, managing weeds, and applying nitrogen and other nutrients are all tasks completed before tassel. We might apply a fungicide, insecticide, or foliar nutrition as needed after tassel, but unless irrigation is an option, August and September are usually spent preparing for harvest and praying for optimal weather – warm days, cool nights, and ideal rainfall.
Many growers experience Physoderma Brown Spot in their corn crops each year. Disease pressure has increased over the past decade due to higher yield conditions and excess water. The disease is caused by Physoderma maydis, a fungus that overwinters in the residue of previous crops.
Pre-plant and planting applications are the most critical passes through the field each growing season. Ensuring that fields are weed free, that there are proper nutrients in the soil, and making a perfect planting pass contribute to a successful, high-yielding crop. Here are some helpful products and practices to ensure your winter wheat crop gets off to a great start.
Over the last ten years, Italian ryegrass has become an increasingly more significant issue throughout the Delta. This weed poses the potential for substantial yield loss in many crops grown throughout the region, especially corn. It is highly competitive with corn during the early portions of the growing season.

The R5 growth stage signals the beginning of the end of the grain fill stage. Many believe that once the grain is fully dented, the crop is safe from yield loss, but that is hardly the case. Much is left to be gained or lost during the “dent stages” of grain fill.
Harvest soybeans as quickly as possible to reduce the likelihood of increased quality issues. Seed quality rapidly declines once problems begin due to inclement weather in the fall. If poor-quality grain is present when bad weather hits, you might see a more rapid deterioration in a short period, regardless of weather patterns and rainfall.

Target Spot is a soybean disease caused by the Corynespora cassiicola fungi. Before 2010 it would have been considered a minor disease in soybeans in the Mid-South and Southeast regions of the United States. However, detection of the pathogen has significantly increased in recent years. Many would argue that it is one of the more prevalent diseases observed in soybeans in the South and in cotton fields. Susceptible cultivars can experience yield losses of up to 18 to 32% when favorable conditions are present but rarely result in significant yield losses in the Mid-South.

Has Tar Spot spread to your area? What are the impacts of this disease on corn in the Midwest? Steve Gauck, Beck’s Hybrids Eastern Team Regional Agronomy Manager, hosts a panel of Eastern Agronomy Team Field Sales Agronomists to discuss the latest corn disease to hit the Midwest – Tar Spot. Steve receives answers from agronomists Mike Hannewald, Aaron Brooker, and Travis Burnett on Tar Spot ranging from its history, key identification tips, and management practices to lessen its impact on yield and plant health.
Applying Enlist One® + glyphosate at 10 gal./A. never resulted in greater than 70% (waterhemp) and 75% (fall panicum) control. However, by upping our spray volume from 10 to 15 gal./A., waterhemp control increased by 17%, and fall panicum control increased by 20%. Why did two systemic herbicides, Enlist One and glyphosate, have such a large response to carrier rate? Even though complete coverage is not as crucial, the herbicide must still reach each plant. Putting the Power in the Pre™ generally leads to reduced weed pressure and greater control; therefore, a pre-emerge was withheld from these demonstration plots to ensure enough vegetation was present at the time of the post-emerge treatment. When increasing from 15 to 20 gal./A., we saw less response with Enlist One + glyphosate vs. Enlist One + Liberty®. When Enlist One + glyphosate was applied at 20 gal./A. (compared to 15 gal./A.), waterhemp control only increased by 3% and fall panicum control by 1%. Note that in heavy vegetation scenarios, 20 gal./A. may still be needed with Enlist One + glyphosate.

The XtendFlex® system allows farmers to utilize an approved dicamba formulation as well as Liberty® and glyphosate. Beck’s Practical Farm Research (PFR)® data shows that using multiple effective SOAs in the pre-emerge resulted in fewer waterhemp for the post-emergence application to control. What is the relationship between the pre-emerge application and post-emergence application? If more money is spent on the pre-emerge application, can less be spent on the postemergence application? In 2021, the Beck’s PFR team set out to determine how the pre-emergence application impacted the post-emergence application and, conversely, how the post-emergence application impacted the pre-emergence application in the XtendFlex system. This study was designed to evaluate various programs in the XtendFlex system that target heavy, medium, and low waterhemp pressure.

XtendFlex® provides farmers the opportunity to utilize an approved dicamba formulation such as XtendiMax® or Engenia®, as well as Liberty® and glyphosate. Though some of our problematic weeds are resistant to glyphosate, there are several that glyphosate remains highly effective against. Glyphosate is also strong on many of the weeds that Liberty is weak on, such as cocklebur, velvetleaf, and grasses. Growth regulators such as Engenia or XtendiMax will be highly effective on broadleaf weeds but have no activity on grasses. The XtendFlex system allows farmers the opportunity to utilize Engenia or XtendiMax in the pre-emerge or early post-emergence application, providing short-term residual with no potential crop response. An additional option could include applying Liberty, separately, in-season to control any escaped weeds.

The foundation to a successful herbicide program starts with the Power in the Pre™. A successful pre-emerge herbicide can help reduce the amount of weed pressure in the post-emergence application. Many post-emergence applications are sprayed in the earlier vegetative stage. However, data shows by delaying weed removal until the post-emergence trip, a significant yield reduction can occur. This highlights the negative impact of early weed competition and demonstrates the Power in the Pre.

The Enlist™ system provides farmers the opportunity to utilize 2,4-D choline, Liberty®, and glyphosate. Beck’s Practical Farm Research (PFR)® data shows that utilizing multiple, effective SOAs in the pre-emerge resulted in less waterhemp for the post-emergence application to control. In 2021, Beck’s PFR set out to determine how the pre-emergence application impacted the post-emergence application and, conversely, how the post-emergence application impacted the preemergence application in Enlist E3® soybeans. The study was designed to evaluate various programs in the Enlist system targeting heavy, medium, and low waterhemp pressure.

Coverage is king with Liberty®. However, when tank-mixed with Enlist One®, how does nozzle type, orifice size, and PSI restriction change our Liberty management? Products like Enlist One are systemic herbicides, so coverage is not as crucial compared to contact herbicides like Liberty. With Liberty, we strive to have medium droplets to ensure proper coverage. However, tank-mixing Liberty with Enlist One will restrict our droplet size from medium droplets to coarse and ultra-coarse droplets. Applications of Enlist One require a specific PSI as well as nozzle. These restrictions result in different management practices vs. applying Liberty by itself, or Liberty with glyphosate. Enlist One + Liberty provides very effective control of glyphosate-resistant waterhemp. It’s key to understand these management practices if planning to utilize this tank-mix. Beck’s Practical Farm Research (PFR)® data has shown an advantage to Enlist One + Liberty over Enlist One + glyphosate for waterhemp control.
