We have yet another round of fall armyworms infesting bermudagrass here at the station. Others have reported picking up some FAW larvae in late-planted soybeans. Continue reading

Bollworm in cotton and soybeans
20
Aug
2021
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. Continue reading

Another Round of Fall Armyworm
16
Aug
2021
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. Continue reading

Palmer amaranth Escaping Auxin Herbicides as well as Follow Up Liberty Application
26
Jul
2021
We have visited fields where growers have found that Palmer amaranth that escaped an auxin herbicide (Engenia, XtendiMax, Enlist One) application also escaped follow-up glufosinate (Liberty) application (Pictures 1 and 2). Auxin herbicide-resistant Palmer amaranth was documented in Tennessee last year. As such, it was not a surprise to find dicamba or 2,4-D fail to control pigweed. Glufosinate-resistant Palmer amaranth was documented in Arkansas last year. We have not found glufosinate-resistant Palmer amaranth on the Tennessee side of the river. However, the reports from these fields has us concerned the glufosinate-resistant biotype has indeed crossed the river. Part of the reason for the concern is that we had research fairly close to these suspect fields that showed similar poor Palmer control with dicamba or 2,4-D followed by glufosinate. Continue reading

Manage Large Palmer amaranth Escapes
16
Jul
2021
We have visited fields where growers assumed their Engenia or XtendiMax + glyphosate had controlled Palmer amaranth only to find that many had escaped and are now quite large (Picture 1). The question is what are some approaches to manage these escapes? Continue reading
