    More and more reports are coming in of corn testing positive for vomitoxin, with levels as high as 6-10 ppm in some cases. Some of these numbers are taking producers by surprise. Although the weather has been favorable for ear rot development, and consequently, grain contamination with vomitoxin, test results could be misleading in some cases, and may even be incorrect. Since there is not a lot you can do about grain contaminated with mycotoxins, you should at least check to make sure that you got a fair test.

    While never a recommended practice, this is definitely not the year to “store” corn in the field and delay harvest. Reports of lodging and downed corn are increasing across the state. Stalk rots are largely responsible for the problem which have been promoted by stressful production environments and susceptible hybrids. Affected corn stalks are characterized by internal plant tissue that has disintegrated and often appears “hollowed out”. These symptoms are also often present in the crown of the plant.

    This harvest season, safety should be a priority within the farm operation. Consider that it is a time that involves long hours and the need for multiple pieces of farm equipment working simultaneously to complete a crop harvest. The continuous activity, diminished daylight and stresses that can be associated with harvest can often lead to agricultural related injuries. Common injuries during fall harvest include slips, trips and falls; blunt trauma incidents; sprains / strains; and injuries due to fatigue.  Some simple ways to reduce the risk of an injury during harvest include:

  5. (Editors note: The following article is being reissued as it appeared in 2011 when we had a very wet fall. The information in it is still relevant today. Unlike 2011 we have had a nice dry fall when we can actually use tillage when it is needed to alleviate compaction, such as ruts left this summer during spraying or over the previous few years.

    Ohio's corn and soybean crops experienced exceptional growing conditions in 2015, including record rainfall in June and July followed by a drier than normal August conditions in many areas. The persistent rains saturated soils and caused localized ponding and flooding. These conditions resulted in root damage and N loss that led to uneven crop growth and development between and within fields. Agronomists often question the value of test plot data when adverse growing conditions severely limit yield potential.

    This season, farmers are at high risk of having a field fire during corn harvest.

    The conditions present during harvest season include dry plant material and grain dust that are highly combustible.  Hot equipment or engine sparks are great ignition sources.  It is not uncommon for exhaust pipes or catalytic converters to exceed 1,000°F. Add a little wind and there is a perfect opportunity for a field fire.

    Protecting grain quality and ultimately the economic value of the grain begins long before the first acre is ever harvested.  This pre-harvest activity is to prepare grain harvesting, handling and storage equipment and structures for the soon to be harvested corn and soybeans.

    This is the time during the growing season when crop tours and seed companies start posting yield predictions for corn. Most of the corn crop in Ohio is probably at the dough stage (R4). Given the tremendous variability in crop quality across the state and between and within fields, it will be particularly interesting this year see how close yield estimates come to matching what's harvested this fall. Moreover, although there may be little or no yield from many fields damaged by excessive rainfall and saturated soil conditions (and related problems, e.g.
