Sauk Centre Hay Auction Summary Sept 17 2015


I am listing links to view my summary information from the September 17 Sauk Centre Hay auction and other hay markets and crop news.
It was very difficult to make dry hay in some parts of Minnesota through the summer months; and difficult to combine and bale straw for small grain in some areas. It could be helpful to check for signs of moisture issues on hay and straw this year. As with other commodities, moisture can make a difference when buying "by-the-ton."

1. September 17, 2015 Summary - All loads sold, grouped and averaged based on bale and hay or bedding type.

2. History of selected lots - averages for recent years, and each sale so far this year, Grass Hay 5-9% Protein, Straw

3. Graph of Medium Square Groups from RFV 101-200. The Red Line is for the last year. For June through September, the black vertical line represents range in prices.

Updated forecasts indicate high corn yields, but stalk rots create harvest concerns

by Jeff Coulter, Extension Corn Specialist

Much of the corn in Minnesota is rapidly approaching maturity (black layer), with some corn already mature. Updated yield predictions on September 16 by University of Nebraska researchers continue to forecast high corn yields for most of the Corn Belt, including two locations in southern Minnesota: https://cropwatch.unl.edu/corn-yield-forecasts-sept-16-2015.

Herbicide resistant giant ragweed control: Alternative herbicide options are limited

by Lisa Behnken, Extension Educator, Fritz Breitenbach, IPM Specialist SE Minnesota, Jeff Gunsolus, Extension Agronomist, Weed Science, and Phyllis Bongard, Content Development and Communications Specialist, University of Minnesota

With the increase in herbicide resistant weeds and no new herbicide chemistries on the horizon, what options remain for good weed control? Achieving acceptable weed control is particularly challenging in parts of Minnesota where giant ragweed is resistant to both SOA 2 (ALS inhibitors) and SOA 9 (glyphosate) herbicides.

Agronomic Practices to Optimize the Rotational Benefits from Alfalfa to Corn

Jeff Coulter, Extension Corn Specialist

Corn crops that follow alfalfa usually benefit from reduced or eliminated nitrogen requirement from fertilizer or manure, increased yield potential compared to following other crops, and reduced pest pressure. A recent Extension bulletin describes agronomic practices for alfalfa termination and the two subsequent corn crops that help utilize the benefits of alfalfa: http://z.umn.edu/rotation.

Are you happy with your weed control in soybeans this fall?

by Lisa Behnken, Extension Educator, Fritz Breitenbach, IPM Specialist SE Minnesota, Jeff Gunsolus, Extension Agronomist, Weed Science, and Phyllis Bongard, Content Development and Communications Specialist, University of Minnesota

PRE-outlook-pursuit
Figure 1. Weed escapes in soybean treated with a single preemergence herbicide application of Outlook and Pursuit on May 5. Photo taken August 6.

With waterhemp becoming more widespread throughout the state and glyphosate resistance increasing, how do your soybeans look this fall? If they look like Figure 1, it may be time to change your weed control strategy.

One strategy for dealing with glyphosate resistant waterhemp is to layer soil residual herbicides. This approach is being evaluated in Rochester, Minnesota and includes a number of residual herbicides in single and two-pass applications. The herbicides in the trial include 1) Dual (s-metolachlor), 2) Outlook (dimethenamid-P), and 3) Warrant (acetochlor). They were selected because of their known effectiveness for controlling waterhemp and their flexibility in application timing. Pursuit (imazethapyr) does not control ​this population of ​waterhemp​ (ALS resistant)​​;​ however, ​it was applied in tank mixes with the pre-emergence herbicides to eliminate other broadleaf weeds.

Updated corn yield, maturity, and freeze injury predictions for the Corn Belt

By Jeff Coulter, Extension Corn Specialist

Much of the corn in Minnesota is in the dent stage and silage harvest is underway. Corn in Minnesota generally reaches maturity (black layer) at 55 to 60 days after silking, corresponding to September 15 to 20 for most of Minnesota’s acres this year.
