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

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

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!

“Fall soil samples collected after harvest (up to 6 weeks after the R8 growth stage) can be useful to monitor changes in [root-knot nematode] population densities or to make management decisions for the subsequent cropping season. Soil samples should be collected at an 8 to 10-inch (20 to 25-cm) soil depth within the root zone of the previously existing crop.”

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 will reduce inoculum.

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 to wear proper personal protection equipment, if necessary, for examining grain bins.

Anthracnose is likely the most prevalent stalk rot in the eastern United States. Affected plants have shredded pith and die prematurely. Anthracnose also causes a distinctive blackening of the stalk rind.
The fungus overwinters in corn residue and infects plants through the roots or by spores that splash onto the stalk or are carried by insects that may introduce them into feeding wounds. The disease usually does not appear until late in the season and occurs more severely where corn follows corn, especially in reduced tillage.
Resistance to anthracnose is available in some hybrids. If a hybrid is resistant to stalk rot, it is not necessarily resistant to the leaf blight phase. Rotation and tillage will reduce inoculum.

Many diseases survive in crop residue like tar spot, northern corn leaf blight, red crown rot, sudden death syndrome, and Fusarium head blight.
Knowing the risks for your field can help inform future management decisions, like choosing disease-resistant hybrids or varieties for next season.
