The foundation of 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 stages. However, data shows by delaying weed removal until the POST trip, a significant yield reduction can occur. This highlights the negative impact of early weed competition and showcases the Power in the PRE.

One of the first steps to a successful herbicide program is starting clean to allow the pre-emerge herbicide to reach the soil surface. The burndown also allows the opportunity to utilize other “effective” sites of action (SOA) that can’t be used in-season such as Gramoxone® SL 2.0. Spraying early in the spring provides the opportunity to control winter annuals like marestail and emerging summer annuals such as giant ragweed. When evaluating spring burndown options, we must consider if the herbicide has burndown only activity or burndown plus residual activity. Products like Liberty® and Gramoxone SL 2.0 will not have any residual activity but will provide very effective burndown activity. Other burndown products such as Sharpen® or metribuzin will provide residual value depending on the herbicide rate.

Benjamin Franklin once said, “An ounce of prevention is worth a pound of cure.” This quote can be applied to weed management today. Preventing weeds from emerging protects yield. University data indicates that growers will sacrifice 2.5% of their final yield for every leaf stage that a postemerge application is delayed. When it comes to post-emerge applications, the best weed to control is a weed that never emerged.

In the weed science world, we spend a lot of time discussing soybean herbicide programs, but very little time talking about corn programs. Why is so little time spent on corn? One reason is the fact that we can use Group 27 or HPPD herbicides in corn to achieve effective weed control. HPPDs were approved in the late ‘90s, making them the most recently approved herbicide group to come to market. Therefore, there are fewer resistant weeds reported compared to many other herbicide groups. Today, Group 27 herbicides are the foundation to many successful corn herbicide program. However, in 2020, farmers in approved states/counties will have the option to use Alite™ 27 (isoxafl utole) for residual on tough-tocontrol small-seeded broadleaf weeds, such as pigweeds and marestail. Alite 27 has greater activity on smaller-seeded broadleaf weeds versus larger-seeded weeds like giant ragweed.

Need help controlling difficult-to-manage weeds this spring? Southern Illinois Practical Farm Research (PFR) Technician and Herbicide Specialist, Joe Bolte, has pre-emergent herbicide management tips to mitigate pesky weeds like marestail, morning glory, cocklebur, waterhemp, giant ragweed, pigweed, lambsquarter, velvetleaf, and foxtails.

Has weed control in soybeans become simple again? In the 2020 growing season, farmers will have more effective soybean post-emergence platforms to select from than ever before. Are the days of having problematic weeds such as waterhemp, marestail, and giant ragweed sticking above the canopy over?

As you start to plan your post-herbicide application trip for your soybean crops, you may be looking for ways to maximize weed control. With the ever-growing list of resistant weeds, proper weed management techniques are more important than ever. Heavy spring rains may cause the pre-emergent herbicides to break down earlier in some fields this year. Therefore, another layer of in-season residual herbicide will be critical this year.

Across the Midwest, finding a window to do field activity has been very challenging this spring. Many farmers find themselves wondering if they should change any of their management strategies as planting continues to be delayed. But, before you make any changes to your 2019 plans, let’s discuss some factors that could influence your growing season.

The fall of 2018 brought many challenges to the region, making it difficult for fall anhydrous applications or a fall burndown. The February issue of CropTalk had the first part of this series. We hope to give you insight on options for spring management if you did not finish your traditional fall fieldwork. The first article, available on the Beck's website, focused on considerations for applying spring anhydrous. This article will focus on how to maximize the efficacy of a spring burndown.

Spring will be here before you know it. So what should you be planning for this spring if you haven’t had a fall burndown put down? Joe Bolte, PFR Operator/Herbicide Specialist at our Effingham, IL., office, asks this question in our latest PFR Report, featuring insights from Dr. Kevin Bradley, State Extension Weed Scientist at Missouri University.
What has three years of implementing water management practices at our Practical Farm Research (PFR)® facility in southern Illinois (SIL) taught us? That in environments that struggle with drainage, tile has payed dividends. Despite the common belief that tile does not work on clay pan soils, our data has proved otherwise.
So, the question is, why did tile work? To gain a better understanding, we must first dig deeper into the soil moisture and temperature data we have gathered over the past three years with CropX LLC moisture sensors.

In times of lower commodity prices, it’s important for farmers to look for efficient ways that they can cut costs without impacting their crop. One area farmers can consider cutting soybean costs is in their fall burndown programs. Before making such a decision, however, it’s important to evaluate the benefits of a fall burndown.
Over the last two years, Beck’s Practical Farm Research (PFR)® team in SIL has tested various water management systems. These studies included drip-fertigation and sub-irrigation studies as well as a tile spacing and tile depth studies. These different water management systems have resulted in some of the highest yields ever recorded at the SIL PFR site to date. In the February 2018 PFR report, we discussed the yield advantages we have seen from tile drainage and irrigation, and many of you asked why we saw such a yield increase.

Beck’s Practical Farm Research (PFR)® data has shown that early planting is one of the keys to maximizing yield potential. In 2017, much of the Midwest faced adverse weather conditions which made it a challenge to find optimum windows to plant early. In such situations, many farmers find themselves wondering what options they have.

When it comes to weed control, a post-emergence (POST) herbicide is one of the keys to a successful herbicide program. Today, there are different options to choose from such as LibertyLink®, Roundup Ready® and Roundup Ready 2 Xtend®. Each platform will have strengths when it comes to weed control.
In times of lower commodity prices, we’re always trying to find new ways to cut cost. One area to consider is cutting costs on soybeans is your fall burndown program. But, before making that decision, you should evaluate the benefits of a fall burndown.

When it comes to growing double crop soybeans, one hurdle many growers face is weed control. One of the most challenging weeds to manage in a double crop soybean system is marestail. In fact, some biotypes of marestail have developed resistance to Group 2 (ALS) herbicides, which are the most commonly applied in wheat. If a population is resistant, the weeds will escape the herbicide application and thus, will be well-established at wheat harvest. The larger the weed, the more difficult it is for contact herbicides to have effective control.
