Answer your Tar Spot Questions with On-Farm Research

By:  Stephanie Karhoff

To growers’ dismay, 2021 is shaping up to be a “good” year for Tar Spot (“good” if you are a plant pathologist at least). Though the combine will have the last say on Tar Spot’s yield impact on corn fields across Williams County, it is already evident that Tar Spot has become more widespread across the county, state, and even the Corn Belt.

Last week, we discussed the possibility of a cold snap limiting any future fall armyworm outbreaks. We did have some fairly low temperatures last week—most areas had 40 to 60 straight hours of temperatures below 65oF (this was the temperature when mortality significantly impacted fall armyworm larvae).  Today, several OSU extension educators have noticed a very large number of adult moths caught in our expanded trap network.  Continue reading

National Farm Safety and Health Week 2021

Farm Safety Yields Real Results
September 19-25, 2021

National Farm Safety and Health Week is a time to turn the spotlight on far too overlooked practices in agriculture. Safety and health always seem to ride under the radar. This week provides a space and platform for safety and health professionals across the country to curate a collective of resources to help farmers address safety and health needs and practices. Yields, loans, conservation efforts, innovative technologies, weather, inheritance tax laws and carbon credits all seem to steal the thunder and the daily headlines, but farm safety yields real results and brings everyone home at night. Take some time out of your week to turn a focus to safety, not just this week but every week! Farmers are always short on time with a long list of to-dos but setting a pace that includes doing things safely can save lives. Put safety first! Talk with your employees and family members today. Schedule safety meetings with employees or conversations around the kitchen table with family to discuss safety rules and the safety culture on your farm. Decide to tackle one area and make it better, then another, and before you know it you will lead by example to your family, employees, and community. The daily topics of focus for this year are outlined below: Continue reading

Predictions for Round 2 of Fall Armyworm

By:  Andy Michel, Kelly Tilmon, Curtis Young, Mark Sulc, Aaron Wilson

“Could Ohio really face another generation of fall armyworm in the next few weeks?” This has been the most frequent question from many of our stakeholders—and rightfully so given the damage we have already seen in forage and turf.  Fall armyworm (FAW) is normally a tropical insect and can reproduce very fast in warm temperatures. In fact, our extension educators found fall armyworm egg masses in the field last week.  Whether or not a new generation of caterpillars will cause damage largely depends on one factor: temperature. Continue reading

Tar Spot more Widespread Cross the State of Ohio in 2021

By:  Pierce Paul, Mark Badertscher, Marian Luis

Contrary to what was observed over the last three growing seasons when tar spot was restricted to a few counties in the NW corner of the state, in 2021, the disease has so far been reposted in 21 counties, including as far South as Clark County and as far east as Holmes County. In the past, the disease was seen late in the season (after R4), but this year it was reported in some fields at or before silking (R1). In most of the effected fields, only a few stromata (black tar-like spots) are observed on a few leaves, but in other cases, large sections of fields are affected and there is evidence of an increase in disease severity (percentage of leaf surface covered with stromata) as the crop matures. Severely affected fields show premature drying and wilting of leaves. Another interesting observation is the different in the pattern of development of stromata among hybrids. Disease severity varies considerable among hybrids; some affected hybrids develop many small spots (stromata) that do not seem to increase in size over time, whereas other hybrids develop fewer, but much larger stromata.
