From Across the Field – Keep Critters Out

Well where did October go? As I look at the calendar it feels like things are getting a bit hectic as we plan for Northwest Ohio Crops Day (February 8th), pesticide certification, and all of our other winter programming. Seems like the holidays will be here before we know it.

Significant progress was made in the last two weeks with regards to harvest, but with the recent and forecasted rainfall, it is looking like the remainder of harvest will be delayed for the time being. With a significant rain system heading our way and poor drying conditions it may take a while before fields are firm enough to access. This has raised some concerns over the standing corn stalk quality. Of course late harvest crop standability is largely weather dependent, however one can expect some lodging if a heavy wind come through the region. Continue reading

Get Ready for a Little Breaking and Entering

Our drop in temperatures throughout Ohio will no doubt convince fall home invading insects that it’s time to seek winter quarters.  These unwelcomed guests typically include Boxelder Bugs (Boisea trivittatus); Western Conifer Seed Bugs (Leptoglossus occidentalis); Magnolia Seed Bugs (Leptoglossus fulvicornis); Multicolored Asian Lady Beetles (Harmonia axyridis); and the most notorious of all, Brown Marmorated Stink Bugs (Halyomorpha halys).

From Across the Field – Feels Like Fall

Fall is here officially and the drop in temperature, certainly seems to confirm so. For the first time since spring, I threw a jacket in the truck, just in case the wind decided to blow. It would be nice for things to dry out so the crops can continue to mature, for a somewhat timely harvest. While it may have come too fast for some, I tend to enjoy autumn for many reasons, harvest occurs, leaves change, and Big 10 football just to name a few. Continue reading

Local Agronomic Insect Report – 8/27/18

For the week of 8/19-8/25. With western bean cutworm number back in the single digits trapping efforts will now focus in late generation corn borer, which can cause significant damage in late season corn. Barring a drastic increase in ECB moth numbers this will be the last agronomic insect report for the 2018 growing season.

Late-Season Pod Feeding by Bean Leaf Beetle or Grasshopper

By: Kelley Tilmon and Andy Michel, Ohio State University Extension, Previously published in the C.O.R.N. Newsletter

We have heard a few reports of either bean leaf beetles or grasshoppers increasing in soybeans. As we start to approach the end of the growing season the larger concern with these insects is the potential for pod feeding, rather than foliage feeding. Pod feeding directly impacts grain quality. Crop stage is also an important consideration. Continue reading

Japanese Beetles in Corn and Soybean

By: Kelley TilmonAndy Michel OSU Extension Entomologists, previously in the C.O.R.N. newsletter

We have been hearing reports of Japanese beetles in corn and soybean.  These beetles are large with a shiny copper and green color.  Foliage feeding in corn is almost never economic, though economic damage from silk clipping is possible (though rare).  Consider a rescue treatment when  silks are clipped to less than ½ inch and, fewer than 50% of the plants have been pollinated, and the beetles are still numerous and feeding in the field.  Continue reading

Local Agronomic Insect Monitoring Report – 7/31/18

For the week of 7/22-7/28. Western Bean Cutworm numbers have dropped significantly in a weeks time. If you are out scouting the economic threshold is 5 egg masses per 100 plants scouted. Eggs range in color from white to purple (close to hatching) are are usually found on upper leaves of the plant.
