What’s in your Grain Dust?

Information provided by Dr. S Dee Jepsen, State Leader of the OSU Extension Agricultural Safety & Health Program

As many farmers know, grain dust contains more than meets the eye. Moreover, the dust you inhale may also contain microbes, insects, and additional plant fodder. All of which are affected by temperature and humidity fluctuations. It is important to better understand what is in your grain dust, since many biological contaminants have been linked to health conditions like asthma and chronic bronchitis. That is why the OSU Extension Agricultural Safety & Health Program wants to sample your grain dust during a loud out period. See below for study details:

Frogeye Leaf Spot – Is It Worth Spraying in 2019?

By:  Anne Dorrance, Ohio State University

Frogeye leaf spot

Several reports over the last two weeks of heavy frogeye leaf spot pressure in some fields as well as low to moderate pressure in others.  This disease will continue to increase and infect new foliage as it develops on these late planted soybeans. Based on our previous research, only once (2018) in 14 years of studies did applications at the soybean growth stage R5 contribute to preserved yield.  At the R5, the leaf at the terminal is fully developed and the pods at any one of the top four nodes is fully expanded, but the seeds are just beginning to expand.

Estimating Yield Losses in Stressed Corn Fields

By:  Peter Thomison

Many corn fields are still silking (and some are just past the mid-vegetative stages)….so, it may seem a little early to discuss estimating grain yields. However, according to the most recent  NASS crop report, for the week ending Aug. 8, 2019,  25% of the corn crop has reached the dough stage (compared to 63% for the 5 year average). Corn growers with drought damaged fields and late plantings may want to estimate grain yields prior to harvest in order to help with marketing and harvest plans. Continue reading

Identifying late-season caterpillars feeding in corn ears

By:  , Department of Entomology

In the last two weeks, I’ve had many calls, texts and pictures of caterpillars in corn ears (hey, at least some fields have ears). It is important to correctly identify which species are feeding in infested fields, not just to make the right management decision but to be sure that Bt traits are working as expected.

The body surface of corn earworm is rough with small, black spines and dark spots. It varies in body color (brown, yellow, pink, green) and has prominent colorful striping. Photo credits: C. DiFonzo, C. Bauer and M. Roth.
