NEMATODE MONDAY: symptoms of Root-knot nematode damage on roots of soybeans in the field and in the lab after a thorough washing. A close examination in the lab gives a clear view of the large root galls (knots) incited by this pathogen. This helps to distinguish root-galls from trogen-fixing nodules (common on legumes), which rub off easily and are pink/soft inside #Nematode @CropNetwork @soydisease #Soybean

Factors influencing nematicide root protection:

Movement in root: Seed-applied nematicides do not move through the vascular system toward the growing point of the root system, so the amount that comes off individual seeds must come directly into contact with nematodes in soil to mpedes infection. Nematicides that bind to the seed coat are less likely to move into the soil water phase, limiting the “zone of protection” around roots.

Movement in soil: Nematicides that have low water solubility are less likely to be distributed in the soil water phase than those with a moderate solubility. Nematicides that have limited movement in the soil water phase, due to low water-solubility, have a smaller “zone of protection” with less protection further from the seed.

Nematode population density: Seed-applied nematicides are marketed for use at low nematode densities. When nematode densities are severe, this usually means there are more nematodes outside the zone of root protection, but still within the zone of root expansion. In this scenario, risk of infection remains high, as roots expand beyond the nematicide “zone of protection.”

Red crown rot is familiar to many in the southeastern U.S., but Midwest farmers should be paying attention, too.

We sat down with Dr. Carl Bradley of the University of Kentucky to discuss the disease and its growing impact.

Foliar fungicides boost yield only when disease is present, says @ISUExtension #SoyResearch funded by @IowaSoybeans. Trials provide data for decision tools and reveal the prevalence of fungicide resistance in common diseases. #SoyCheckoff bit.ly/3UIwVi1

Storing mycotoxin-affected grain:

✅Dry affected grain quickly.
✅Remove damaged grain.
✅Manage your grain bins.

The hardest part about soybean grain quality analysis…..finding a place to stash the mountain before you can evaluate it! That’s the “finished” pile!! @T_birdPathology @JMHuoni

🤝 Ento crew for the assist today

Winding things down this week…..cotton harvest coming to an end in Stoneville @TylerBTowles @JMHuoni @T_birdPathology

Are farmers really using disease predictive models? 🤔
Who's actually using these tools? Agronomists, farmers, or bankers?

What's your take?

NEMATODE MONDAY: shooting a video to promote the Soybean Nematode Management Guides with my take on Root-knot nematode. We have developed guides on soybean cyst, root lesion, reniform & root-knot nematode. All excellent resources for soybean farmers @CropNetwork @SON_nemaweb

Attention Span Crisis: The 6-Second Rule

We test the best corn hybrids in fields all across the state.

This provides impartial data to help select hybrids and enhance profit.

Thanks to all the growers, eight participating seed companies, and Extension agents who make this happen.

Wondering if ripping increases soybean yield? Our 2026 data show a 5.5 bu/ac increase from fall ripping compared to no ripping at the 75% confidence level on non-irrigated ground in Starkville. More to come from @MSSOY @MSU_AG @MSUEFieldCrops

On this episode of I See Dead Plants, we're digging into the science of plant disease forecasting and exploring how models can help growers anticipate disease risk before the damage is done!

Fusarium stalk rot causes shredded pith that may be tan to light pink. Brown streaks may be observed on the lower internodes.

The fungi overwinter in corn residue, other dead plant residue, and in corn seed.

Resistance to Fusarium stalk rot is available. Rotation and tillage @DTelenko @badgercropdoc @MandyBish1 @MartinChilvers1 @maddishires @alisonrISU @TamraJacksonZ @baldpathologist @NationalCorn #corn #harvest26

Working through purple seed stain and grain quality plots this week. Honestly, very little purple seed stain….but have a few plots with a good bit in a large Cercospora leaf blight variety trial @T_birdPathology

Regularly monitor bins for potential issues.

If grain becomes wet, use fans to increase airflow and reduce grain moisture levels, preventing fungal growth.

If mycotoxin-producing fungi begin to grow in high-moisture corn, mycotoxin level in stored grain can increase. Be sure protection equipment, if necessary, for examining grain bins.
