    In April we reported that University of Kentucky true armyworm moth counts were higher than average.  These moths migrate northward, so if our southern neighbor reported high catches, many moths also likely made it into Ohio. After migrating and establishing, armyworms begin to lay eggs in grasses, including wheat fields and cover crop fields (that may have corn planted soon). Larvae feed for about 3 weeks before pupating. This article discusses armyworm management in corn and small grains.

    Adult cereal leaf beetles have been spotted in a few areas across OH.  Adults do not normally cause yield loss in wheat, but, if present in high numbers, they could lead to heavy larval infestations over the next few weeks.  Adult cereal leaf beetles are shiny, metallic blue and orange and are best found using a sweep net or by walking the field.  Cereal leaf beetle larvae are small, gray and moist, resembling bird droppings, and are easily found on wheat leaves.  Foliar damage on wheat occurs when larvae feed and strip the leaves, causing a “frosted appearance.”  Economic threshold of cere

    There are many reasons why on-farm grain storage is used by producers across Ohio. It may be part of the marketing strategy, feed storage for farm use, and/or income and tax management to complete grain sales before and/or after the new calendar year. Regardless of the reason, an essential requirement is to maintain quality grain during the storage period to preserve the grain for end usage and economic value. 2016 presented some grain quality challenges, especially for corn so it will be important to manage the grain during the next several months.
