Often times people get caught up in looking at the negative things that have happened. Delayed planting, washouts, replants and everything else in-between. In the end, focus on maximizing yield potential in the fields that are most uniform and are on pieces of ground that offer the best chances for a solid return on investment. It is impossible to fix problems with spacing or stand at this point, but it is the perfect time to make a good management decision. Maximize yield potential where you can in 2013.
Fungicide use has been increasing each year with many of you looking for ways to improve timing and rates. Some have a spray everything approach while others have the scout and spray approach. Each situation is different and every outcome can be different. In heavy disease pressure fields, such as multiple years of corn, the decision tree can look different. A two pass approach, one at V6-V8 to save on application costs with POST spraying, and a VT timing. Research has shown that if you are adding a second application, the V6-V8 window is a good place to start. Growers looking to continue to utilize a single application should target the VT timing. A single application at V6-V8 will not have the same yield potential benefits as a single application at VT.
For an early application, heavy residue is a good option as well because of the high likelihood for anthracnose infection. Anthracnose has two significant yield robbing stages – a leaf blight phase and a stalk rot phase. An early application can reduce the chances of experiencing a significant yield robbing infection by controlling the early leaf blight stage of the disease.
