@erinm_nelson @MNelson_ISU Love this - especially the focused look on TJ’s face!😊

[Jim McDermott @jfmcde]

@erinm_nelson You just had a nightmare. 😩

[Jim McDermott @jfmcde]

Based on projected GDU accumulation, corn planted yesterday in Northern Iowa should emerge May 1 - 3. This will be the time to start to take stand counts. 👀@DKCAsgrowNWIA @Bayer4CropsUS

[DEKALB Asgrow Seed @Asgrow_DEKALB]

As farmers prepare to evaluate this year’s crop for the first time, learn about how corn and soybean stands are assessed and what to do after. 🌽🌿 https://t.co/EJPWp6IO15

[Jim McDermott @jfmcde]

Great info on soybeans as we get close to the start of the planting window in Northern Iowa. @DKCAsgrowNWIA @Asgrow_DEKALB @Bayer4CropsUS

@jim_mcbucket That’s exactly what I suggested.

[Jim McDermott @jfmcde]

@pete_90210 @DKCAsgrowNWIA Very good yields but variable. It’s early yet but not the best yields I’ve seen overall.

[Jim McDermott @jfmcde]

Harvest is going strong in NWIA with corn moistures in the low 20’s. Want harvest data this Fall - sign up below. @DKCAsgrowNWIA

@RosburgAg @DKCAsgrowNWIA Good to hear! Not bad for third week of September.

[Jim McDermott @jfmcde]

Northern Corn Rootworm Beetles having a party in NW Iowa. Easy to see why we have to manage for rootworm even on rotated acres. DEKALB has great options with traits like SmartStax Pro, SmartStax and VT4P. @Asgrow_DEKALB @DKCAsgrowNWIA @BayerTraits

[Jim McDermott @jfmcde]

@pete_90210 I believe that’s a buildup of Anthocyanins. Looks like no sink (ear) to move them into so they accumulate in the leaves and stalk.

[Jim McDermott @jfmcde]

This new DEKALB hybrid - DKC108-64 - has looked outstanding in the field. It also contains the SmartStax Pro trait which has shown to have superior corn rootworm control vs. anything on the market. Talk to your dealer early. @Asgrow_DEKALB @DKCAsgrowNWIA @BayerTraits

[Jim McDermott @jfmcde]

@rfeeck @Asgrow_DEKALB @DKCAsgrowNWIA @Bayer4CropsUS Thanks Ryan!

[Jim McDermott @jfmcde]

I’ve been proudly representing DEKALB hybrids for 28 years as of today. Two great ones here I’ll continue to represent going forward. I wouldn’t want to be anywhere else as an employee or as a customer! @Asgrow_DEKALB @DKCAsgrowNWIA @Bayer4CropsUS

[Jim McDermott @jfmcde]

@pete_90210 @Asgrow_DEKALB @DKCAsgrowNWIA @Bayer4CropsUS That’s awful nice of you to say Pete! Thanks.

[Jim McDermott @jfmcde]

@ToddClaussen @Asgrow_DEKALB @DKCAsgrowNWIA @Bayer4CropsUS Thanks Todd! That means an awful lot coming from you.

[Jim McDermott @jfmcde]

@PaulKassel Could that be DKC59-81 or DKC50-87?

[Jim McDermott @jfmcde]

With fungicide applications going on currently in this extreme heat, I would not be surprised to see this in Iowa. Good video. @DKCAsgrowNWIA

[Crop Protection Network @CropNetwork]

We requested a soybean disease update from @baldpathologist with @MSUExtService.

Dr. Allen talks fungicide phytotoxicity in soybeans in the video.

Current situation in Stress Degree Days. We’ll see what this looks like in a week. 😳

[Eric Snodgrass @snodgrss]

Heading into this week's Midwest heat wave, I wanted to post the current accumulated stress degree day map.

Calculated by adding degrees above 86°F for each day.
Example: if today is 95°F, 9 SDDs are accumulated

>140 SDDs could result in corn yield loss

Data: PRISM April 1

@alisonrISU @NicoleStecklein @PioneerVande @MNelson_ISU @rkvittetoe No - fairly decent tolerance. The Goss’s Wilt hasn’t spread much in the field or in the canopy yet.
