If you missed the Corn Inservice webinar, we’ve broken out the five presentations, which are available to view now at the UT Crops YouTube channel.
The University of Tennessee Extension is working with our State USDA Farm Service Agency (FSA) to increase awareness of CFAP money that is available to assist crop, livestock, and dairy producers. Continue reading
Generally, a nutrient deficiency occurs as a result of low soil nutrient levels. However, prevailing environmental conditions, soil properties, and growth conditions may restrict nutrient uptake and induce deficiencies in crops even if soil nutrient levels are deemed sufficient for optimum yield. For example, low or high soil pH, soil compaction, and excessively wet or dry soil may prevent nutrient uptake. A handy diagnostic tool to identify nutrient deficiency in crops is via visual symptoms. In some instances, this tool may not provide a definite diagnosis of the nutrient status of the plant. Keep in mind that there are other conditions that are cable of inducing symptoms that closely resemble those of nutrient deficiencies. Visual symptoms should be corroborated with tissue and/or soil testing. Adequate knowledge of visual symptoms and tissue testing may help guide corrective actions in-season or preventive action in the following season to avoid yield loss.
This past week samples from Chester, Lauderdale, and Montgomery Counties in Tennessee were confirmed to have southern corn rust, so the question is do you need to put out a fungicide application… Continue reading

A reminder that moth trap catches are reported weekly for corn earworm (bollworm), tobacco budworm, and southwestern corn borer. You can find these data under the Quick Links menu of this web site which takes you to the link below.
We are also seeing an increase in bollworm moth catches. I’m hopeful many of these moths will target later corn rather than cotton or soybean, but Continue reading
Relatively low disease has been observed in Tennessee so far. The warmer winters most areas had may have allowed survival of disease inoculum and paired with storms coming from the south could result in more disease development this season, so scouting and correctly identifying diseases are important.

It’s been a generally quite week for insect problem but below are some reminders and suggestions.
Cotton: Most cotton is past the stage where thrips are a concern. Tarnished plant bugs will now be our primary focus for much of the season. Thus far, most reports indicate a slow and sporadic start with plant bugs, but treatments are now being made more widely. However tempting, I encourage people to avoid using Continue reading
