Retailers and the basic suppliers are all very concerned about herbicide shortages in 2022. We all can recall similar concerns this past spring. In most cases applicators were able to get what they needed . However, this spring retailers were often able to fill shortages by accessing carryover from 2020. I have been told there will be no carryover herbicides to fill holes in 2022 so the probability of herbicides not being available is much more likely. Continue reading
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
Growers still interested in entering the Top Bean soybean yield contest should submit an entry form by end of day this Friday, September 3rd. Continue reading
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
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
Entry forms will be collected through Friday, September 3rd for the 2021 Top Bean yield contest. Continue reading
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
As soybean fields are blooming, disease scouting needs to start to guide fungicide application decisions. Continue reading
