Giant ragweed, if left unchecked, will compete with slower growing soybean plants for critical resources and can significantly reduce yield, with losses reaching as high as 30-90 percent in soybean field trials. The Plant Management Network (PMN) has released a new presentation entitled “Herbicide Resistance in Giant Ragweed” for growers, crop consultants, and extension agents discussing the biological characteristics that make giant ragweed problematic in soybean production and how its increased resistance to herbicide impacts potential control strategies. The webcast, developed by Bill Johnson, Professor of Weed Science at Purdue University, chronicles giant ragweed’s increasing resistance to herbicide varieties [...]
For soybean growers facing high seed costs and low commodity prices, any insights into reaching optimal seeding rates and planting times can help raise profit margins. The Plant Management Network (PMN) has released a new presentation entitled “Risk and Benefits of Changing Farmers' Common Soybean Seeding Rates” to help growers and crop consultants maximize economic returns on soybean seed investment. The webcast, developed by Peter Kyveryga, Director of Analytics at the Iowa Soybean Association, analyzes the results of multi-year field studies measuring how seeding rates, planting time, and other factors affect yield. The data indicates that planting date was [...]
Shawn P. Conley, professor of agronomy at the University of Wisconsin-Madison, produced a webinar focusing on how extreme weather events and climate variation over the past 30 years have affected soybean yields. Topics he reviews include which months are most susceptible to yield loss from extreme weather, the importance of developing a strategy specific to your location, and which areas are most prone to future monetary losses. View the 12-minute webinar here.
Sudden death syndrome wreaked havoc in fields across the Midwest U.S. and Canada in 2014, resulting in much yield loss and frustration for farmers. Although selection of resistant cultivars is the best management option for SDS, other management options may complement resistance. A new webcast titled “Soybean Death Syndrome Management Update” and published in the Plant Management Network’s Focus on Soybean resource, highlights three years of research focusing on these complementary options. The talk, authored by Dr. Daren Mueller, Extension Field Crop Pathologist at Iowa State University, offers practical information on SDS management through: Seed treatments Planting date Glyphosate [...]
Soil sampling is critical to ensuring adequate levels of nitrogen, phosphorus, and potassium, as well as managing soil PH. The payoff: achieving good nodulation and, in turn, high yields. The latest ‘Focus on Soybean’ presentation, titled “Soil Sampling to Make Fertilizer Recommendations” by Dave Mengel, Professor of Agronomy at Kansas State University, covers the ins and outs of soil sampling, from the process itself to interpreting data from the testing lab. In this talk, Mengel discusses: Where to take samples in a field How many cores are needed to make a good composite sample What depth the sample and [...]
Fungicide resistance management has become a priority issue in the soybean industry this year, especially as fungicide resistant strains of Cercospora sojina, the pathogen that causes Frogeye Leaf Spot, were confirmed in 10 states. To help manage and avert fungicide resistance, the United Soybean Board awarded a research and education grant to sustain fungicide effectiveness and help growers and crop consultants manage fungicide resistance through outreach. Dr. Carl Bradley, the principal investigator on the grant, teamed up with the nonprofit publisher Plant Management Network to produce the Soybean Fungicide Resistance Hub, a central destination for valuable information on soybean [...]
Now more than ever, growers are experiencing yield loss and crop quality due to fungicide resistance, forcing them to either use more fungicides or select disease-resistant varieties that aren’t necessarily the highest yielding for their growing conditions. Fungicides are an important weapon against plant disease and, now more than ever, it’s important for agricultural practitioners to manage this resistance. Through a United Soybean Board grant-funded research project led by Carl Bradley, Associate Professor of Plant Pathology and Extension Specialist at the University of Illinois, the Plant Management Network has published a new ‘Focus on Soybean’ webcast to help facilitate [...]
Fungicide resistance can be a major threat to soybean disease control, and this resistance can take hold quickly if fungicides and their applications are not properly managed. In an attempt to help combat this ever-present issue, the United Soybean Board funded a grant to ‘sustain fungicide effectiveness through fungicide resistance education for growers and crop consultants.’ As part of the outreach efforts for this grant, the Plant Management Network and a team of researchers led by Carl Bradley, Associate Professor of Plant Pathology and Extension Specialist at the University of Illinois, produced the first in a series of three [...]
The Illinois Soybean Association (ISA) checkoff and membership programs represent more than 43,000 soybean farmers in Illinois. The checkoff funds market development, soybean production and government relations efforts, while the membership program, Illinois Soybean Growers (ISG) and the Illinois Soybean Growers PAC actively advocates for positive and impactful legislation for farmers at local, state and national levels. ISA upholds the interests of Illinois soybean farmers through promotion, advocacy, research and education with the vision of becoming a trusted partner of Illinois soybean farmers to ensure their profitability now and for future generations.
