After splitting stems, the pith of a plant infected with SDS will be white even if roots are severely rotted...
SDS management strategies include planting soybean varieties with SDS resistance, managing SCN, using effective fungicide seed treatments, improving soil drainage in fields with recurring SDS, rotating crops, avoiding or reducing soil compaction, and maintaining proper pH and fertility levels. Growers must plan on implementing an integrated SDS management strategy, because a single management tactic alone is not likely to adequately control the disease."

If your ISU Extension Field Agronomists were to host multiple Fertilizer and Finance workshops (2-3 hours) around the state to help you make fertility plans for this fall, when do you prefer to attend? Feel free to share this post.
ISU Hay Day - July 13 in Boone!
ISU Hay Day is a half-day program packed with practical knowledge for anyone making hay in Iowa. Join us from 9:30 AM - 2:00 PM.
No cost to attend. Lunch provided.
Registration: https://t.co/ggptY3zzku
More Info: https://t.co/kWkUla3dfe
@BobGunzy @LDBell8675309 @DanAllred1 Some fields through Monroe county look very similar. Plus ~13 inches of rain since June 1 near Russell. Mother Nature giving SC IA all of the challenges that it can think of thus far.
Some significant storm damage occurred through Lucas, Mahaska, Marion, and Monroe county (likely others as well) this week with hail, wind, and flooding all occurring. Check out https://t.co/WwdYZjnQeR for more information about assessing damage following the storms. #ISUCrops
Alright, I think we’ve had enough fun with you Mother Nature. 😬
Crop Scout School is always one of my favorite events each year! A big thanks to @IAStateWeedSci @alisonrISU @ashleyn_dean @LoganMccrea @VirgilSchmitt @Tunweeds and Mark Licht for helping teach. Time to hit the fields! #ISUCrops #CropScout
Some SC IA March planted soybeans doing their best to fight through the mud… hope they’re ready for a couple more rounds of storms. #ISUCrops
We’d like to interrupt March Madness with this announcement:
📣 Registration is now OPEN for the 2026 ISU Crop Scout School. We will be offering two Crop Scout Schools this year, but space is limited!

Last day of Planter U here in Otley. Great conversations and learning being had. Big props to @ISUDigitalAg for all of their hard work this week. #ISUCrops @rkvittetoe
Have you registered for a Crop Advantage Series meeting yet? 12 locations with tailored, locally relevant sessions at an affordable price! https://t.co/3my2wpDvPw #ISUCrops
We are thankful for all the 2025 Integrated Crop Management Conference sponsors! Two days, 33 sessions, up to 14 CCA continuing education credits, and LOTS of coffee and networking! Thanks for joining us this year! #ICMConference #ISUCrops
Private pesticide applicator training #1 of too many to count down! Thank you to Mahaska county for a good crowd yesterday.

Out here checking rootworm traps and think I took a wrong turn into the Oompa Loompa factory… wait that’s just the southern rust popping up across south central Iowa! 😅 @ashleyn_dean @alisonrISU
Bit of a wet morning that turned into a beautiful afternoon for the Hay Day at McNay. Smaller but mighty crowd with tons of great interaction and conversations. Thanks to @Tunweeds for presenting during lunch! @ISUCropNews
@JansenStuart Very valid points. It’s tough planning haying extension events as when it works good for us is when it also works good for producers. And we certainly don’t want you all to skip out on good haying weather! Thank you for the feedback.
