I was thinking it might be 2021 or at least 2020 before we would start getting reports of Xtend soybean fields that were wrapped up with Palmer amaranth. Wrong! It is 2019. I visited several soybean fields this week where, judging by the Palmer amaranth regrowth, Engenia had been applied to Palmer that was 2 to 6″ tall (Picture 1). A small percentage died and the rest went on to over run several Xtend soybean fields (Picture 2). In another field a follow-up Engenia application was made and it did improve the pigweed control some but the field was still far from being a success story. Continue reading
CORN PRODUCERS PREPARE FOR HARVEST
Hot, dry weather prevailed over most of the state, providing ample opportunities for fieldwork. Corn producers were busy preparing for harvest with some expected to begin harvesting as early as this week. Soybean and cotton growers sprayed for insects and applied fungicides. Hay baling continued to be a major activity with farmers working on their second and third cuttings. Despite the heat, pastures and cattle looked good for this time of year. There were 6.4 days suitable for field work. Topsoil moisture was rated 4 percent very short, 27 percent short, 67 percent adequate, and 2 percent surplus. Subsoil moisture was rated 3 percent very short, 26 percent short, 64 percent adequate, and 7 percent surplus. The entire report can be read here: TN Crop Weather 08_19_2019. The USDA also released the latest national crop progress report as well. It can be viewed here: US Crop Progress 08_19_2019.
I’ve resisted writing this post for 5 years because I think estimating lint yield from boll counts only provides enough insight to differentiate between poor, decent and good cotton. Still, I understand the temptation to count one’s chickens before they hatch. In this blog, I highlight a few issues with estimates and define the number of bolls required to produce one and two bales at various row spacings and patterns. Continue reading
The Tennessee Wheat Variety Trial data from 2019 is now available. To access the publication, click the below image or navigate to this web address: http://news.utcrops.com/wp-content/uploads/2019/08/Wheat-Variety-Performance-Tests-in-Tennessee-2019.pdf
The USDA released the lastest crop production forecast for Tennessee. Corn production in Tennessee was forecast at 160 million bushels, up 38 percent from the previous crop. Yield was estimated at 174 bushels per acre, up 4 bushels from the 2018 level. If realized, this would be the highest corn yield on record. Soybean production for Tennessee was forecast at 73.5 million bushels, decreased 4 percent from 2018. Yield was estimated at 50.0 bushels per acre, up 4.0 bushels from a year ago. If realized, this would tie the highest soybean yield on record. Tennessee farmers expect to harvest 14.9 million bushels of winter wheat during 2019. The expected crop for 2019 would be down 20 percent from the previous year.
Tennessee cotton production is projected to be 940,000 bales, up 22 percent from last year. Cotton yields are forecast to average 1,128 pounds per acre, up 87 pounds per acre from the previous year. Producers expect to harvest 400,000 acres, up 45,000 acres from 2018. The entire report can be read here: Crop Production Forecast for TN 2019.
POP-UP SHOWERS DO LITTLE TO HINDER FIELDWORK
Hay baling was the dominant activity across the state last week with pop-up showers doing little to slow the second or third cuttings of hay. Other activities included spraying of fungicides on soybeans and the topping of tobacco. Pastures continued to look good due to the rainfall received over the past few months, but the elevated heat and humidity seen by most of the state placed a great deal of stress on livestock. There were 5.0 days suitable for field work. Topsoil moisture was rated 1 percent very short, 14 percent short, 77 percent adequate, and 8 percent surplus. Subsoil moisture was rated 1 percent very short, 13 percent short, 74 percent adequate, and 12 percent surplus. You can read the entire report here: TN Crop Weather 08_12_19. The USDA also realeased an updated crop condition report that can be viewed here: US Crop Progress 08_12_2019.
Despite a relatively lack luster moth flight, corn earworms (a.k.a. bollworm or soybean podworm) are showing up in some late maturing soybean fields, and as usual the action in centered in the river bottom. The treatment threshold for corn earworm is based on sweep net sampling and using the table below. Continue reading
