Once you’ve sample your field, had it tested, and you have soybean cyst nematode (SCN), you’ll want to consider SCN-resistant varieties, but there are certain populations of SCN that can reproduce on certain SCN-resistant varieties so how do you know what resistant variety is best for your field – you find out the HG Type of your population – a costly test that UT is offering for free this year to TN farmers.

After harvest – don’t forget to soil sample!
After harvest is the perfect time to take soil samples not only for nutrient analysis but also to look for pathogens. You’ll never know if you have silent yield robbers lurking in the soil unless you look for them – Take the test, beat the pest! Continue reading
What’s the difference between nematodes?
The last two weeks we’ve published articles highlighting the free soil testing for 2018, which is screening for the ‘silent yield robbers’: pathogenic nematodes and charcoal rot. This article gives a brief description on how pathogenic nematodes differ – their effect on yield and different management options. Continue reading
Soilborne Pathogen Screening: 2017 Results and 2018 Screening
Last week’s article discussed soilborne pathogens as ‘silent yield robbers’ of crops in production fields and the importance of screening. This article elaborates on two of the most common pathogens found in soybean fields, soybean cyst nematode (SCN) and charcoal rot, and presents the results from our 2017 soil screening.

Free Soil Testing for Pathogens
Don’t miss out on the opportunity to have your soil tested for parasitic nematodes and charcoal rot at no cost for Tennessee Farmers ($15 fee for out-of-state samples). Continue reading
Reminder: Soybean Disease Field Day – Tuesday, Sept. 4, 2018
Wondering what’s been making your soybeans sickly? Come to The University of Tennessee Soybean Disease Field Day, held Tuesday, Sept. 4th, at the Milan Research and Education Center. Registration will be from 8:30-9:00 AM with the tour beginning at 9 AM and concluding with a box lunch. Preregistration is not required. Pesticide re-certification and CCA points will be available. Field demonstrations will include soybean disease identification, UT variety trials, fungicide efficacy trials and other UT disease research trials. Hands on disease identification will cover main soybean diseases that occur in Tennessee including frogeye leaf spot, target spot, Cercospora leaf blight, southern stem canker, sudden death syndrome, and others.
Soybean diseases, fungicides, and soil sampling
Most soybeans have gotten into reproductive growth stages and diseases may have started appearing although at low levels. To better identify diseases and guide management decisions use the resources below… Continue reading
Relatively low disease in Tennessee corn
With no reports of southern rust in Tennessee or to the south, it is a relatively quiet disease season in corn, with the exception of grey leaf spot and physioderm brown spot in Tennessee corn. Continue reading
