Selecting Cotton Cultivars with Nematode Resistance and Tolerance. Check out this new resource from Extension at https://t.co/v4UGoFmEv0. By @JeffBarizon @MandyBish1 @StrayerScherer @bobkemerait @cropdisease @DaisyHAhumada @alabamaED @IanMSmall1 @intiazchowdhury @cropdoc08

Soybean Cercospora leaf blight disease cycle. This disease reduced soybean yield by more than 3.3 million bushels in 2024. Extension has resources at https://t.co/NBQK2iulo5 @ppp_trey @baldpathologist @LSUAgCenter @travisfaske @dsmuelle @ISU_IPM @SpurlockLab @T_birdPathology

“The impact of plant diseases on soybean...was estimated across 29 states and Ontario, Canada from 2020 to 2024...Diseases reduced soybean yield by an estimated 1.2 billion bushels...valued at $14.6 billion USD for the survey period. Per acre, this estimated mean economic loss

The best way to manage Goss’s wilt is to plant highly resistant corn hybrids. Additional control can be achieved by rotating crops with non-hosts (soybean, dry bean, small grains, alfalfa) to help reduce the primary inoculum for the next corn crop. Because the bacterial pathogen

Most corn hybrids are susceptible to southern rust, but a few resistant hybrids may be available. Resistant hybrids may contain a specific type of gene (known as an Rpp gene) that confers resistance to southern rust. Some moderately-susceptible hybrids may be available that do

“When SDS pressure was high (FDX ≥ 10), both SDS-targeted treatments had 7.0 to 9.0% more yield than the base.” From the @PlantDiseaseJ article "Soybean Seed Treatment Evaluation under Various Levels of Sudden Death Syndrome and Populations of Soybean Cyst Nematode"

Yield loss from corn disease: 2.5 billion bushels. Economic loss from corn disease: $13.4 billion USD. This is summary data from the newly published "Corn Yield Loss Estimates Due to Diseases in the United States and Ontario, Canada, from 2020 to 2023." Find out more at

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

“[Soybean cyst nematode] populations are slowly but steadily overcoming the resistance genes from the PI 88788 source of resistance and to a lesser extent Peking. Thus, it is critical that soybean growers rotate the sources of resistance in varieties they select.” From the

"Results emphasize that fungicide applications occurring at VT/R1 and when disease severity exceeds 5%, are more likely to result in positive economic gain." Read more in the new @phytofrontiers article at https://t.co/JRiORbl56C. From @NabinKDangal @badgercropdoc

Wheat streak mosaic, High plains disease, and Triticum mosaic are part of a virus disease complex found in most wheat growing regions of the U.S. and into Canada. This disease complex can cause major losses in spring and winter wheat. Some virus-resistant wheat varieties exist.

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

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. Initially, these areas are narrow, water-soaked lesions, but they turn

Congratulations to @JeffBarizon for earning a @cafnr Driver to Distinction Award! Jeff was surprised by Dean Daubert & the Division Director Buecking today. Well done, Jeff!

Ugly ears. Some may contain mycotoxins. Test grain and whole-plant silage for mycotoxins if 10% or more ears have rot. Obtaining a good sample for testing is critical for accurate results. Read more at https://t.co/uLeklcA3Jk. @badgercropdoc @baldpathologist @MartinChilvers1

The presence of ear rot diseases should be a key consideration when determining harvest timing. Fungi that cause ear rots can continue to grow, spread, and produce mycotoxins after corn reaches maturity and during storage if grain is not dry. Read more at

If corn ear rots are a significant problem, it's essential to test grain and silage for mycotoxins. Getting a good sample is critical. Find out how at Extension's https://t.co/uLeklcA3Jk. From @badgercropdoc @baldpathologist @MartinChilvers1 @travisfaske @dsmuelle @ppp_trey

Scouting is similar for all corn ear rots. Starting at late dent stage (R5), choose 20 ears from 5 areas in the field. Pull back the husk to see the entire ear. It's critical to identify ear rots in the field as several ear rot fungi produce mycotoxins, which can harm livestock

Severe foliar disease can weaken corn stalks. Test stalks using the pinch test and prioritize harvest for that field if 10 percent or more stalk rot. Ask local Extension for more info. @alisonrISU @DTelenko @MandyBish1 @maddishires @MartinChilvers1 @badgercropdoc @tjcksn
