Author:  Comments Off on Bicentennial Heritage Festival This Saturday (Jackson, TN)

Be sure to stop by the West TN Research and Education Center this Saturday (Oct. 9, 10:00 AM – 4:00 PM) for this event commemorating our agricultural and rural heritage on the bicentennial of many counties in the region becoming a bona fide part of Tennessee. This should be a great event for families and the weather is looking good!

Join us at 605 Airways Blvd, Jackson, TN, 38301


Stink bugs and kudzu bugs in soybeans

Author: and  Comments Off on Stink bugs and kudzu bugs in soybeans

Many soybeans in Tennessee have entered the reproductive stages and this is a critical time for scouting insects.  This is especially true for fields in the later development stages with seed forming in pods as they are very attractive to several species of stink bugs, which are seed feeders.

Bollworm in cotton and soybeans

Author: and  Comments Off on Bollworm in cotton and soybeans

The bollworm flight overall this year has been low, slow and a trickle flight.  Moth traps indicate that we have an increase in moth activity in spots and this is occurring later in the season than normal.  Bollworm can be a significant pest of cotton and soybeans, particularly late soybeans that are just flowering during the flight.  As such, the large 2021 wheat crop that was planted to double crop soybeans in June and July will need to be monitored.  Wide row soybeans are especially attractive to moths.

Another Round of Fall Armyworm

Author: and  Comments Off on Another Round of Fall Armyworm

We are currently experiencing another round of fall armyworm in bermudagrass here at the station in Jackson.  We wouldn’t be surprised if there were other outbreaks occurring elsewhere.  Please be vigilant in scouting bermudagrass pastures and sorghum Sudan grass.  These larvae can do a lot of damage in a short amount of time so please be on the lookout!  Please refer to a previous blog for treatment recommendations.

The fall armyworm outbreak of 2021 is going to be one to remember.  My colleague, Dr. Gus Lorenz in Arkansas called it “epic”.  We knew something was different this year when another colleague in Texas, Dr. David Kerns, gave us a warning over a month ago.  So what’s different? First, the fall armyworm flight is several weeks early, second, larval infestations have been unusually high, and third, for whatever reason, control with pyrethroid insecticides has been unusually poor (ranging from sometimes acceptable to a complete failure).

Using the Thrips Infestation Predictor for Cotton

Author:  Comments Off on Using the Thrips Infestation Predictor for Cotton

A reminder the Thrips Infestation Predictor for Cotton described in the article below, published last year, is still available for use.  However, the link has changed to  https://products.climate.ncsu.edu/ag/cottontip/.

———————————————————————-

The Thrips Infestation Predictor for Cotton is a useful tool for predicting whether a foliar insecticide application is needed for thrips control in cotton. It uses local weather data in association with a user defined planting date to estimate the size of the local thrips population, the susceptibility of seedling plants, and thus, the risk of thrips injury. The model is for tobacco thrips, by far the most common species infesting cotton in Tennessee. Continue reading

If you haven’t noticed, our UTcrops.com website has gotten a facelift.  You may not recognize it when you first visit us at  https://utcrops.com/.  However, it’s organized similarly to the old version.  I’m sure there are a few bugs that need to be fixed, but take a look!  This site gives you ready access to essentially all UT resources related to row crop production.
