Well it’s a start anyhow. Most folks are dodging weather trying to get seed in the ground. With limited crops emerged, it is not too surprising that I’ve not been getting many calls about pest problems. The most frequent calls are listed below, along with some management tips and some photos. Continue reading
Questions continue to arise on management of glyphosate-resistant (GR) Johnsongrass in corn, soybean and cotton. GR Johnsongrass continues to become more of an issue with each passing year. The main threat with Johnsongrass is in corn where there are few POST applied options. Continue reading
Dr. Heather Kelly discusses seedling disease symptoms and scouting in our latest Call of the Week. Continue reading
Clearly this year, many are having trouble managing ryegrass and poa. Questions began months ago and continue today and have ranged from tactics to burn them down before planting to how to control them in a standing corn crop. What has become abundantly clear is that glyphosate is no longer an effective burn down option for either species across much of the state. Continue reading
In this podcast, Dr. Larry Steckel answers questions about the newly approved over-the-top dicamba product, Tavium, the looming May 15 cutoff for older dicamba formulations, dicamba volatility research and buffer zones. Click to listen.
A new, very impressive cotton planting conditions calculator has been created by Dr. Guy Collins and Dr. Keith Edmisten with help from the Climatology Office at North Carolina State University. In this post, I highlight a few of the features and provide an example of how the calculator works.
DRIER CONDITIONS BOOST PLANTING
Drier conditions allowed farmers back into the field on a limited basis. Corn, soybean, and cotton planting continued. Strawberry harvest and the first cutting of hay began. Winter wheat responded well to the warmer, drier weather, as did pasture and forage conditions. There were 4.7 days suitable for fieldwork last week. Topsoil moisture rated 73 percent adequate, and 27 percent surplus. Subsoil moisture rated 1 percent short, 71 percent adequate, and 28 percent surplus. Hay and Roughage Supplies rated 16 percent very short, 25 percent short, 52 percent adequate, and 7 percent surplus. Continue reading at TN Crop Weather 04_29_19.

All week we have discussed UTIA’s latest research on low-volatile dicamba formulations. We will end this series of blog posts with one of the first questions asked by TN soybean producers: Does adding glyphosate to low-volatile dicamba formulations increase its chances of moving outside the treated field via volatility?
