It is cover crop burndown time. There is no one size fits all recommendation for cover crop control. It really depends on the environment and the cover crop species in the field. With respect to environment, cover crop burndown can be tricky during periods of long stretches of saturated soil conditions. This is particularly true with systemic herbicides where translocation of those herbicides to growing points can become limited. Continue reading
There are three newer corn herbicide premixes available: Acuron GT, Armezon PRO and Resicore. Below are some thoughts on these newer premixes as well as some that have been around for a spell: Continue reading
This spring some fields seem to be infested more heavily with wild garlic, grape hyacinth and in a few cases, star-of-Bethlehem. These three weeds, in the Lily family, are often mistaken for each other as they all derive from bulbs and are low-growing perennials. Continue reading
Prickly sida or tea weed has increasingly become more of an issue in soybeans. There are two reasons for this. First, the Group 15 herbicides (Dual Mag, Warrant, Zidua) are the most common PRE-applied herbicides utilized. Though that group of herbicides provides good residual control of pigweed and grasses, it provides no help on sida. Second, is that glyphosate nor dicamba has ever been very effective on this weed. The only POST option that can give some control is Liberty. However, even Liberty is limited to controlling only very small (<3”) prickly sida. Continue reading
The combination of some lingering supply chain issues, most notably Sharpen and Verdict are in tight supply, with the ever-increasing presence of herbicide resistant weeds has made burndown time more of a challenge. On a positive note, glyphosate is in great supply and down in price about 40% compared to last year. Continue reading
We have gotten several reports of wheat showing metribuzin injury this week. In some cases it clearly was caused by metribuzin (Picture 1). In other cases, the visual injury would suggest frost damage (Picture 2). Continue reading
The Environmental Protection Agency (EPA) has proposed additional mitigations and regulations on the use of atrazine. The open comment period will close this Friday October 7. If you are interested in commenting see this link. I know that it is a very busy time of year but please consider making a comment on this topic. You all are the experts since you steward this herbicide, on many acres, each spring and your comments have more value than many that are sent. Continue reading
Every fall we travel around the state and observe the overall success or failure of weed control in our row crops. From the Palmer amaranth standpoint a few too many fields look like a failure. Particularly, from Gibson county across to Lauderdale county cotton and soybean fields ranged from clean fields to fields with more weeds than one would like (Picture 1) to completely grown up pigweed messes (Picture 2).
