Weed Management in Double Crop Soybeans
Double the crop, half the weed control – that’s part of the allure of following wheat harvest with a second planting of soybeans. However, this approach involves different weed spectrums, residual herbicide timing decisions, and spray cut-off dates to consider.
IL Crop Conditions Getting Worse?
On the latest episode of the ILSoyAdvisor podcast, the Soy Envoys discuss Illinois crop conditions, emergence issues, "floppy corn," ongoing weed scouting, and pest concerns such as slugs, Japanese beetles, and stinkbugs.
Understanding the Crop Injury Risks of PRE Herbicides in Early-Planted Soybeans
As farmers continue to plant soybeans earlier, there are concerns about preemergence (PRE) herbicide injury to emerging seedlings. Supported by the Illinois Soybean Association, the University of Illinois Crop Sciences department is evaluating different PRE herbicides on early-planted soybeans to give farmers access to crop injury ratings for better weed management decisions.
Does Late Planting Mean Delayed Yields?
The 2024 planting season has been marked by significant variability, especially in planting dates. This raises the question: should soybean fields planted in mid-May be managed like those planted in April? According to IL Soy Envoy Drew Beckman, the answer is yes, and he provides reasoning in his latest blog.
Monitoring Root Development and Planning for Fungicide
Crop conditions across the state remain highly variable, and the IL Soy Envoys share their regional updates. This episode also covers wheat harvest, root establishment issues, slug damage, crops in the "ugly duckling" phase, herbicide misapplications, and notes for fungicide season.
Post Dicamba June 12th Cutoff & 85 Degree Temperature Reminder
The application cutoff date for dicamba use over-the-top of soybeans is June 12th, and the projected forecast for much of the state shows elevated temperatures for the week. IFCA understands the pressure ag retailer members face to control weeds with available crop protection products, but violations of the cut-off date, temperature restriction, or recordkeeping requirements will be considered willful violations of the Illinois Pesticide Act, so it is crucial to discuss label requirements with customers to ensure compliance.
Crop Scouting During the Awkward Junior High Stage
In a "normal" year, Stephanie Porter's focus would be on scouting V7 corn and R1 soybeans. However, with corn planted at varying intervals this year, it's essential to approach each field with a different mindset. Read on to see her photos and observations from the field.
Which Insect Pests and Diseases Cause the Most Damage to Soybean Stems in Illinois?
Researchers collected over 200 diseased stems from 59 counties in Illinois between 2022 and 2023 to address gaps in understanding soybean stem pests and diseases. Based on this data, Dr. Nick Seiter highlights the significance of dectes stem borer in no-till fields in south-central Illinois, while Dr. Jason Bond discusses prevalent diseases such as fusarium, stem-canker, and charcoal rot across various counties, offering management strategies to combat these issues.
“Way Too Early” Soybean Yield Predictions
In the latest podcast episode, the Soy Envoys share challenges posed by highly variable crop conditions, including yellowing in fields, persistent waterhemp problems, and root development issues. They also share their "way too early" soybean yield predictions and offer a detailed crop report from their region.
Soybean Phytophthora Stem and Root Rot Resistance Genes Have Become Less Effective
Managing soybean Phytophthora stem and root rot starts with variety resistance. A recent study led by Michigan State University determined that previously relied upon resistance genes are failing and there is a need for soybean breeders to incorporate new sources of resistance.
