For the week of 6/17-6/23. No traps at the economic threshold for treatment for Western Bean Cutworm (WBC), European Corn Borer (ECB), or Brown Marmorated Stink Bug (BMSB).
WBC:
Freedom – 3
Monroe – 0
Pleasant – 0
Bartlow – 0
NWARS – 0
ECB:
Freedom – 0
Bartlow – 9 army worm moths in trap
BMSB:
Flatrock – 0 male; 0 female; 0 nymphs
All insect traps have been set. I will report trap counts based on the township the traps are in. In 2018 in Henry County I have traps set for Western Bean Cutworm (WBC), European Corn Borer (ECB), and Brown Marmorated Stinkbugs (BMSB). There is also a WBC trap at the NW Agricultural Research Station near Hoytville.

One billion dollars. Prior to Bt technologies farmers lost $1 billion annually to corn rootworm—in the form of chemical costs or actual yield loss. With resistance to traits that once killed the pest on the rise, it might just nibble its way back to a billion-dollar price tag.
Corn rootworm (CRW) poses a double threat—the adult snips corn silks, and if unchecked could prevent successful pollination and kernel development, and the larvae munch on roots which leads to risk for disease and plant stress. CRW was once controlled by traits but with resistance on the rise is now at risk of running rampant: it’s time to find a solution to slow the spread of resistance.

Late planting in many areas, the small size of both soybean and corn plants, and damp, cool conditions in some areas all lead to a greater damage potential from slugs. Although all fields should be scouted for slugs, focus on no-till fields or those fields with cover crops, a history of slug problems, poor weed control, or a lot of residue left on the field. We don’t have good economic thresholds for slugs in corn or soybean, yet the following guidelines are to helpful in scouting for their presence and intensity. Continue reading The Season for Slugs

The larvae of alfalfa weevil can cause considerable damage, especially when alfalfa is just starting its growth in the spring. When temperatures are greater than 48oF, the adults become active and start to lay eggs. After hatch, the plump and green larvae (which resemble little worms) feed, with 3rd instar (mid-aged) larvae being the hungriest. The heaviest feeding can occur between 325 and 500 heat units. Right now, the heat units (base 48oF) for the Western Ag Research Station in South Charleston are 98, and for the South Station in Piketon is 175. Scouting for larvae should begin at around 250 heat units. Continue reading When to Begin Alfalfa Weevil Scouting
As we progress through the final month of 2017, field operations are winding down across the county. I estimate that there is around 1 percent of the corn crop yet standing and that soybean harvest is all but complete. Still quite a bit of tillage happening in parts of the county, otherwise the 2017 crop year wrapped up. From a very wet start to insect and weed pressure, mix in a dry spell, and finish with a wet end, this year figures to be one talked about for quite some time.

Imagine yourself as a student on the campus of The Ohio State University. It’s a nice, sunny day outside. Students are walking to class, others are having conversation beside Mirror Lake, and in the distance, you see your entomology professor running around with a crazed look in his eyes while waving a comically-sized insect net.
Yes, the latter really happened. The man in question is known as the BugDoc, professor emeritus of entomology at The Ohio State University, Dr. David Shetlar. I had the pleasure of visiting with him recently to ask him something that bugs my brain every year at this time, no pun intended.
Old wives’ tales are something of a hobby for farmers in Ohio it seems, especially when it comes to predicting winter weather. Everything in the Lord’s creation is up for grabs when it comes to telling us how bad the upcoming winter will be. Whether its corn husk thickness, leaf amounts, or wool growth on sheep, something somewhere will tell us winter is coming. Continue reading Do Woolly Worms Really Predict the Winter Ahead?
October is one of my favorite months of the year. It finally feels like fall, harvest is trucking along, there is apple cider aplenty, Buckeye football, and last but not least October is National Pork Month. October received this distinction as it was traditionally the month when most pigs went to market. Therefore, take some time and celebrate by having a pork chop or two in the coming weeks. Continue reading From Across the Field 10/11/2017

Now that fall is officially in the air, a number of insects and spiders are poised to make their way into Ohio homes. Indeed, with the recent spate of cool temperatures, I’ve already gotten a few reports of gnat-like Hackberry Psyllids (Pachypsylla spp.) buzzing around homes and various spiders marching across floors.
