The three-month outlook for July, August, and September currently depicts enhanced odds of warmer than normal temperatures. Meanwhile, the precipitation outlook for the same three-month time period places the region in an area of equal chances of above, near, or below normal precipitation totals (see the map).

Moth traps and southwestern corn borers
As always, moth trapping data for the season can be found on the quick links menu (http://www.utcrops.com/BlogStuff/2017MothTrappingData.pdf). We are now catching a few more corn earworm (bollworm) moths, but nothing too startling. However, it is clear that the second generation moth flight for southwestern corn borer is underway, and we will catch even more moths next week. Keep in mind that there is a lot of variation among locations. It can be a waste of money to treat for southwestern corn borers based on trap catches that are not near your fields. You should be running a few Continue reading
Corn Southern Rust Confirmed in west Tennessee
With the continued wet and warm weather, it didn’t take long to identify Southern rust in some Madison county corn, and additional fields are being scouted this week. Continue reading
Corn Southern rust still not confirmed in Tennessee

Foliar Diseases and Fungicide Applications in Corn
Trying to decide whether or not to spray fungicide on your corn? First, you should scout for diseases and consider your disease risk. Southern rust has been reported in TX, MS, AL, AR, GA, and FL and with the tropical storm there is a good chance spores have been blown in to TN and the wet, overcast weather provides the perfect environment for disease development.

Fall Armyworms Look to Make and Early Start (again)
It seems that fall armyworms have gotten a running start in recent years. This species does not overwinter in Tennessee, but it may survive warm winters in the extreme southern areas of coastal states during mild winters. It migrates into Tennessee each year. Often, fall armyworms don’t show in substantial numbers until late July or August. However, they are being found Continue reading
Don’t freak out about Japanese beetles
They’re back, but they don’t scare me! It is very unusual to see economic damage from Japanese beetles in cotton, soybean, or corn. They may cause defoliation in all crops. I’ve never seen enough defoliation in cotton or corn to justify treatment. On a few occasions, I’ve seen enough defoliation in soybean to catch my attention. They will hang around for a while, so in combination with other defoliators, they may cause enough damage Continue reading
