Good Evening,

This week I had the opportunity to attend the Western Ohio Forage Field Day with Phil Bauer.  This field day focused on grass interseeded into alfalfa, leafhopper resistant alfalfa trials, annual forage alternatives after wheat — conventional, no-till and slurry seeded, nutritional aspects of warm season annuals and corn silage and forage preservation, alfalfa management inputs for high yield, red and white clover variety trials, native grasses for forage and biofuel, grass variety trials, in addition to a hay mower-conditioner demonstration by John Deere and a hay tedder demonstration by New Holland.  I was also fortunate to get a tour of Phil’s Jersey dairy farm and learn how he bases his operation around forages and his new compost manure management barn.  I look forward to attending more field days and events with Hardin County farmers so let me know if you are thinking about attending one in the future.

The Hardin County Agriculture Hall of Fame Committee has updated its Purpose and Nomination form.  I have attached the updated form in both Microsoft Word and Adobe pdf formats for your use.  The committee would like to see someone nominated for this year’s Ag Hall of Fame from each school district so that we have good representation from the entire county.  Please take a minute to look over the form and if you know of someone who should be nominated, feel free to share the information.  The committee will also have copies of the form available in the Ag Hall of Fame booth in the Machinery Building at the Hardin County Fair.  Applications are due October 15 to the Extension Office.

There are some insects and late season diseases to be on the watch for in soybean and corn fields.  This week questions focused on soybean aphids and when it is necessary to treat for them.  See the following articles for further information regarding these and other issues that may be of interest to you.




What Soybean Diseases to Scout for Next  – Anne Dorrance

Downy mildew, Sclerotinia (white mold), Sudden Death Syndrome, and Soybean Rust are included in this article that can be found at  Images of soybean diseases can be found at  Take note of the recommendations for each disease if you see it in your field and be aware of the economic level for that disease when making management decisions about treatment.



Corn Growth and Yield Potential: Impact of Recent Cool Weather –  Peter Thomison

Have recent below average temperatures adversely affected corn growth and yield potential?  No, corn actually yields best with moderate temperatures (and adequate soil moisture). Temperatures that occur in Ohio in July and August (especially at night) are often warmer than optimum for corn. The ideal daytime temperatures for corn are about 80 to 86 degrees F (and higher if moisture is plentiful at all times).  Continue reading this article at



Keep Scab Resistance at the Top of Your List as You Select Wheat Varieties This Fall – Pierce Paul, Clay Sneller, Rich Minyo

Even though we did not have high levels of scab and vomitoxin this year, we still need to keep this disease in our minds as we select varieties to plant this fall. In the past, there were very few Ohio-grown winter wheat varieties with decent scab resistance, and some of those varieties yielded poorly or did not grow well under our conditions. Today we have far more varieties with very good scab resistance in combination with very good yield potential.  Read more about selecting wheat varieties at



Changes to Insecticide Labels Coming Related to Bees -Ron Hammond, Andy Michel

In an ongoing effort to protect bees and other pollinators, the U.S. Environmental Protection Agency (EPA) announced last week that they have developed new pesticide labels that prohibit use of some neonicotinoid pesticide products where bees are present. However, because few products containing these insecticides are used in field crops for foliar spraying especially during flowering or pollination (mainly on soybeans), any label changes should not have major impacts for field crops.  More information can be found at



Turfgrass Rust – OSU BYGL

Does your yard have rust on the grass?  Rust, a fungal disease (Puccinia spp.) of turfgrass, has been reported throughout the state.  Rust affects all common turfgrasses used in the United States but in Ohio it is most common on Kentucky bluegrass and perennial ryegrass.  Turfgrass rust is typically seen in late summer and fall.  Find out more about Turfgrass Rust which is caused by cool temperatures and moist conditions at
