Although some parts of Illinois have started to get beans in the ground, most of us are still waiting for soils to dry out and warm up. Something that should be on our radars in the week or two before planting are soilborne insect pests that may affect our soybeans. Wireworms and white grubs are the two pests of importance in Illinois, and on occasion these insect larvae can cause significant reductions in stands and early season plant vigor.... Read More →

Webinar: Solutions to Effectively Manage SCN and SDS
March 13, 2017
Jason Bond, plant pathologist at Southern Illinois University, and Nick Tinsley, SeedGrowth™ technical representative at Bayer CropScience, discuss the basics of SCN and SDS management. They review where these pests thrive, symptoms of infestation and impact on yield, as well as conventional management practices and how new seed and seed treatments provide control.
Key Takeaways:
- About SCN
- 80% of Illinois fields are infested; growers should assume they have it
- Once a field is infested, it’s always infested
- Resistant varieties are widely available, but most of the resistance is from a single source
- You can have no visible symptoms and still have 30% yield loss
- 80% of Illinois fields are infested; growers should assume they have it
- About SDS
- Since 2004 the disease has been localized
- Quantitative resistance
- Controlled by multiple genes
- Difficult to test in the field
- Resistance is stable
- Since 2004 the disease has been localized
- Short- and long-term implications
- Very few farmers sample their fields for SCN
- SCN problems are going to get worse in the near future
- A frequent sampling program will help growers keep it in check
- Varieties with different sources of resistance are coming to the market thanks to recent genetic discoveries about the parasite
- Select seed treatments can help mitigate SCN for the time being
- Very few farmers sample their fields for SCN
- ILeVO®
- Protects again both SDS and SCN, including:
- Root rot
- Nematodes
- Foliar symptoms of SDS
- Not a replacement for fungicide-based system
- Affects multiple stages of the SCN infection cycle
- Primarily affects hatching and motility
- Protects again both SDS and SCN, including:
Illinois Soybean Association
The Illinois Soybean Association (ISA) checkoff and membership programs represent more than 43,000 soybean farmers in Illinois. The checkoff funds market development and utilization efforts while the membership program supports the government relations interests of Illinois soybean farmers at the local, state, and national level through the Illinois Soybean Growers (ISG). ISA upholds the interests of Illinois soybean producers through promotion, advocacy, and education with the vision of becoming a market leader in sustainable soybean production and profitability.
