Soybean replanting decisions are almost always a tough call and a subjective decision. In 2023, favorable planting conditions in late March and early April have resulted in quite a few acres being planted. As we head into the month of May, let’s take a look at some objective factors that can help inform replant decisions. Continue reading
Mitigating Potential Herbicide Mixing Issues
This time of year as we move to burndown behind the planter we typically get some reports of mixing issues when either glyphosate or Gramoxone is added to the tank with residual herbicides like atrazine, metribuzin, Cotoran, Caparol, fomesafen or a pyroxasulfone containing product. What happens is the white herbicides will often clabber up and stop up screens and strainers in the sprayer. Continue reading
Thinking ahead: Vine Control in Corn
Practically every September some growers are dismayed at the vine infestations present at corn harvest. Often, these weed infestations emerged after PRE applied or early POST applied herbicides had played out. They grew very little until August and as the corn dried down and light became more available those established weeds started rapidly growing. Continue reading
Another April cold snap, too close for comfort
Yet another cold snap moved through the area this past weekend and several had questions concerning the possibility of this event to damage our wheat crop. I’ve pasted a copy of the NOAA observed low temperatures throughout most of Tennessee’s wheat producing areas, and as you can see from the image temperatures fell very close to dangerous levels. Additionally, frost was reported in several areas. Continue reading
Ryegrass Management in Corn
There were a number of reports of ryegrass escaping burndown in fields that either will soon be planted to corn or just had been planted to corn. Thankfully this issue seems less of a problem than a year ago. In most cases the ryegrass escaped glyphosate + dicamba early burndown. Paraquat application has the best probability of controlling ryegrass that has escaped early burndown. Continue reading
Little to no wheat diseases in Tennessee 2023
So far only some bacterial streak and Septoria/Stagonospora have been reported in Tennessee wheat. Continue reading
Tennessee Market Highlights- 04/14/2023
Corn and wheat were up; soybean was mixed; and cotton was down for the week.
On Friday, April 14, the old crop–new crop corn futures spread expanded to $1.06 ¼ per bushel the largest spread between the May and December futures contracts since May 16, 2022. The price spread is amplified in cash markets in Tennessee, due to strong old crop basis compared to current new crop basis offerings. There remains a large amount of uncertainty in price direction for new crop corn. However, based on current market information there continues to be a bearish undertone in new crop prices. Managing price risk through purchase of out-of-the money put option contracts, for the new crop, is worth considering at this juncture. This strategy can be used to mitigate a portion of the futures price risk and buy time until more information is known about the 2023 crop. If new crop prices rise, the option position can be exited and a portion of the premium recovered. Continue reading at Tennessee Market Highlights.
Application Time of Day Affects Gramoxone Performance on Some Weeds
With the planting season started, many people are thinking about using Gramoxone (paraquat) as a burndown for many weeds present at planting. Gramoxone is a very good broad-spectrum herbicide that has been the go to for burndown of many winter and summer annual broadleaf weeds. With Palmer amaranth starting to emerge, Gramoxone is the only sure thing that will control it. However, it is less consistent controlling some weeds like horseweed (marestail). Continue reading
