There have been a good number of calls on sketchy Palmer amaranth control with a 12.8 oz/A of Engenia or 22 ozs/A of XtendiMax mixed with a quart/A of Roundup PowerMax. I visited a number of these fields last week and indeed anywhere from 14 to 20 days after application some Palmer amaranth were recovering. Continue reading
In this week’s podcast, Dr. Larry Steckel recaps highlights from the annual Weed Tour and addresses weed questions he has received this week. Listen.
Catchy title eh? No major insect problems are occurring on a wide basis, but the phone is ringing more frequently about several issues. Continue reading
Good early-season management of tarnished plant bugs relies on a sweep net, monitoring square retention, and making timely insecticide applications as needed. During the first two weeks of squaring, the recommended treatment threshold is an average of 8 or more plant bugs per 100 sweeps. After that, treatment is recommended anytime of infestations average 15 or more plant bugs per 100 sweeps Continue reading
A reminder that moth trapping data are updated weekly at http://www.utcrops.com/BlogStuff/2019MothTrappingData.pdf, and you can also access these data on the Quick Links of this site. Pheromone-baited traps are run for corn earworm (bollworm), tobacco budworm, and southwestern corn borer.
With the exception of some notable hotspots for southwestern corn borer, moth trap catches are generally low, as typically observed this time of year.
HOT, DRY WEATHER PREVAILS
Hot, dry conditions dominated most of the state allowing farmers to make significant progress planting corn, cotton and soybeans. These same conditions also placed stress on emerging crops and had some wishing for timely rains. Harvest of first-cutting hay continued to be a major activity as producers took advantage of excellent baling conditions. There were 6.3 days suitable for fieldwork last week. Topsoil moisture rated 8 percent very short, 31 percent short, 57 percent adequate, and 4 percent surplus. Subsoil moisture rated 5 percent very short, 22 percent short, 68 percent adequate, and 5 percent surplus. You can continue reading the Tennessee Crop Weather report at TN Crop Weather 06_03_19. Also, the U.S. crop progress report can be reviewed at US Crop Progress 06_03_2019.
Many questions continue to be asked on how best to manage grass in cotton. The sketchy performance of glyphosate on goosegrass, junglerice and Johnsongrass in 2018 is the main driver of these questions. Continue reading
