A) How will Delaying Corn Harvest Affect Yield, Grain Quality and Moisture?-Research Findings - Peter Thomison, Allen Geyer, Rich Minyo

Leaving corn to dry in the field exposes a crop to unfavorable weather conditions, as well as wildlife damage. A crop with weak plant integrity is more vulnerable to yield losses from stalk lodging and ear drop when weathering conditions occur. Additional losses may occur when ear rots reduce grain quality and can lead to significant dockage when the grain is marketed. Some ear rots produce mycotoxins, which may cause major health problems if fed to livestock...

E) Fall Herbicide Treatments in Wheat - Mark Loux

There is time yet this fall to apply postemergence herbicides to wheat for control of winter annual weeds and dandelion. While winter annual weeds can be controlled with an early spring herbicide application, our research over the past 9 years or so in various crops indicates that herbicides are most consistently effective on winter annuals and dandelion when applied in fall...

F) Get Your Fertilizer Spread This Fall or Next Spring, But Avoid Frozen Ground Applications - Robert Mullen, Keith Diedrick

As you continue to harvest crops, plan on getting your fertilizer down this fall prior to frozen ground setting in or plan on waiting until spring after the thaw. Considering the number of acres that did not receive phosphorus or potassium last year with the prices we were facing, some of you may be in a situation where soil test indicates that you should make the application this year. If that describes your situation there is still time to make your applications this fall...
