Corn Newsletter : 2014-34

    Cool, wet weather and delayed soybean harvest may result in planting wheat late.  Generally, the best time to plant wheat is the 10-day period starting the day after the fly-free-safe date.  In northern Ohio, we are close to the end of that 10-day period.  In central and southern Ohio, we still have about a week before the end of the 10-day period.  When wheat is planted more than 10-days after the fly-free-safe date, there is an increased chance of reduced fall growth and reduced winter hardiness.  The effect of planting date on wheat yield is shown in Figure 6-2 of the Ohio Agronomy Guide

  2. Soybean Aphid on Overwintering Host Buckthorn.
    Author(s): Andy Michel

    Two observations on soybean aphids surprised us in 2014.  First is that we saw soybean aphids at all.  Since 2001-when soybean aphids were first detected in Ohio-we have had aphid outbreaks every other year (i.e. in odd numbered years).

    We are now in transition season.  We expect the rest of October to become more active with rain chances every 2-4 days.  We will be in a battle zone between high pressure near the East Coast and low pressure near the central U.S. leaving Ohio and the Ohio Valley in the transition zone for stormy weather.  Temperatures will swing from above to below to above normal with the overall trend close to normal for temperatures.  Frost and freeze chances will be increasing but we are on track for about a normal frost and freeze season in October.
