Planning management strategies for this disease will depend on how much you have and if it warrants action for the 2016 season, says University of Nebraska-Lincoln Extension.

Ben Pederson shares his journey to adopting strip-till and offers six lessons to other growers considering strip-till or zone tillage.

As you travel over your field with your herbicide this season, you may be considering adding a fungicide to that pass. If so, there are a few things to think about. In general, early fungicide applications on corn (V5-V7) have not been shown to provide much yield benefit over no treatment (average is +1 bushel per acre). In repeated trials across the country, we see the best opportunity for yield response with a treatment at tassel (average: +8 bushels per acre). However, there are some situations in which an early treatment may be more economical.

Corn is all over the board in terms of growth and development, ranging from V6 to R2. Late-planted fields are usually at greater risk for foliar disease development, and reports coming in indicate that gray leaf spot is already present on the lower leaves in some areas.

In 2011, University of Kentucky set up 3 commercial-scale, on-farm fungicide tests in fields of yellow and white corn in West Kentucky.

We have been receiving reports since corn harvest began this fall about an unusual phenomenon: yields of the outside 8 to 24 rows on the south or west edges of corn fields show lower or much lower yields than corn farther into the field. The damage tends to be relatively uniform down or across the field, and is on field edges that border a soybean field, road, ditch, or another short-growing crop (such as forage legumes or grasses) other than corn.

If we could predict or know that the planting season during 2014 would be like it was in 2012 (the dry spring), then we would say don't treat your seed at all. But if the season is like this past year, wet, the combinations of seed treatments did a much better job and at the higher rates. There have been lots of questions over the past few days on what fungicides to apply; what rates to use; and are insecticides always necessary. Here we try to parse it all out for you.

Syngenta and DuPont announced technology licensing agreements that will broaden each company's crop protection product portfolio and enable both to bring new products to market more efficiently.
