    Despite the cold snap a couple of weeks ago, we have continued to catch large numbers of fall armyworm moths (we caught >10,000 moths the last week of September), have found eggs, and have even had reports of damage in cover crops, alfalfa and other forage. The good news is that the extent of the damage is less than we saw during late August and early September. However, the continued warmth over the next week or so may allow fall armyworm caterpillars to do a bit more feeding until the first frost.

    In general, the best time to plant wheat is the 10-day period starting the day after the fly-free safe date. 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 winterhardiness. The effect of planting date on wheat yield is shown in Figure 6-2 of the Ohio Agronomy Guide.
