University Response to Plant Health Label for Headline Fungicide

By WCM Staff on 5/28/2009 8:42 AM

During the past winter, BASF was granted a supplemental Plant Health label for Headline® fungicide. In Wisconsin, the following crops are currently labeled: barley, corn, edible legumes, oats, oilseed crops, rye, and soybean. To date, there have numerous fungicide trials conducted at the University of Wisconsin in field crops like corn and soybean as well as winter wheat over the past few years, including trials that examine multiple active ingredients, different application timings, different crop rotations, and differences in genetics.

Considering Foliar Fungicides for Corn in 2009 - Part 2

By WCM Staff on 5/14/2009 11:35 AM

Much like how we have spent the past few years trying to understand if foliar fungicides are effective in corn grain production, we have received numerous questions regarding their use for corn silage. This is Part 2 of a two part article series explaining the results of out trials.

Considering Foliar Fungicides for Corn Grain in 2009 - Part 1

By WCM Staff on 5/12/2009 11:53 AM

University of Wisconsin Cooperative Extension Service and UW College of Agricultural and Life Sciences initiated a coordinated effort to generate data from replicated on-farm large strip and small plot trials in 2007 and 2008 (and continuing in 2009). The results are presented in this two part article series.

Frost Injury to Alfalfa

By WCM Staff on 5/7/2009 1:32 PM

We are seeing some frost injury to alfalfa leaves. It appears as the misshapen leaf tips shown in the circles of the picture below. Frost can damage leaves in early stages of development and then damage becomes visible as the leaves mature.

Alfalfa winter survival in spring 2009

By WCM Staff on 5/7/2009 8:28 AM

Alfalfa stands have come through the winter in varying conditions depending on previous management and the locally occurring weather conditions this past winter.

Sampling and Managing Soybean Cyst Nematode

By WCM Staff on 5/7/2009 8:15 AM

As we move into planting for the 2009 growing season, this is a perfect time to remind growers of the importance of soil sampling and testing for the presence and population of Soybean cyst nematode (Heterodera glycines; SCN) in fields.

Predicting When Soybeans Will Emerge

By WCM Staff on 4/29/2009 12:00 PM

Ten years ago, very few people outside of academia were concerned about the number of growing degree units (GDU) required for soybean emergence. Today however, things are dramatically different.

Spring Removal of No-till Alfalfa in Wisconsin

By WCM Staff on 4/29/2009 11:23 AM

Many of the same herbicides used in the fall are also effective in the spring and are listed in table 1 along with rate ranges and plant-back restrictions for field corn.

Alfalfa stand assessment, new video online

In this video Dr. Dan Undersander, UWEX forage agronomist, visits an alfalfa field and demonstrates steps you can take to answer this question. Is this stand good enough to keep? >>>http://www.youtube.com/watch?v=jujW3-FE4zE

New article on soybean seeding rates

A new publication from Shawn Conley and John Gaska titled, Factors to Consider When Lowering Soybean Seeding Rates in 2009, can be found at this link. http://soybean.uwex.edu/documents/Factors_to_Consider.pdf

Wheat Stand Assessment

By WCM Staff on 4/16/2009 11:34 AM

Most winterkill that growers experienced in 2008 was related to prolonged ice sheets that limited plant respiration and ultimately lead to plant death. In 2009, Wisconsin wheat growers are again dealing with winterkill; however the culprit this year appears to be death by exposure (lack of snow cover).

Corn plant density

By WCM Staff on 4/9/2009 12:09 PM

The plant density that maximizes corn grain and silage yield has been increasing through time. The economic optimum plant density is a function of corn yield and quality responses, seed cost, and grain or silage price. The economic plant density is lower than the plant density that maximizes yield.

Application techniques Fact Sheet for boom sprayers
