Quick Guide to Soybean Varieties for Iowa with Peking SCN Resistance

Nov 30, 2023

By Dr. Greg Tylka

A recent ICM News article summarized the updated list of soybean cyst nematode-resistant soybean varieties for Iowa, available online here. The publication contains information on 866 SCN-resistant soybean varieties and 5 blends available for use in Iowa for 2024. The list includes 87 varieties with Peking SCN resistance. Varieties with Peking SCN resistance can provide better SCN control and increased yields in fields where varieties with PI 88788 resistance were grown for decades. The tables below provide a quick look of varieties with Peking SCN resistance.

Consult the ISU Extension publication here for information about the herbicide resistance and iron deficiency chlorosis tolerance of the varieties.

The information above and in the ISU Extension publication was provided by the seed companies offering the varieties for sale. Variety availability changes from year to year, so an annually updated list is most helpful.

Video: Dicamba Returns for Georgia Farmers: What the New EPA Ruling Means for Cotton Growers

After being unavailable in 2024 due to registration issues, dicamba products are returning for Georgia farmers this growing season — but under strict new conditions.

In this report from Tifton, Extension Weed Specialist Stanley Culpepper explains the updated EPA ruling, including new application limits, mandatory training requirements, and the need for a restricted use pesticide license. Among the key changes: a cap of two ½-pound applications per year and the required use of an approved volatility reduction agent with every application.

For Georgia cotton producers, the ruling is significant. According to Taylor Sills with the Georgia Cotton Commission, the vast majority of cotton planted in the state carries the dicamba-tolerant trait — meaning farmers had been paying for technology they couldn’t use.

While environmental groups have expressed concerns over spray drift, Georgia growers have reduced off-target pesticide movement by more than 91% over the past decade. Still, this two-year registration period will come with increased scrutiny, making stewardship and compliance more important than ever.
