Mark Loux OSU Soybean Researcher Field Leader

Mark Loux

Professor, Department of Horticulture and Crop Science

Mark Loux’s career in weed science is due in part to his dad, a chemist at one of the major ag chemical companies on the East Coast. “When I was getting a degree in plant science at the University of Delaware, he let me know about their internships,” Loux said. He ended up accepting a summer internship with a company in New York and then moved to Illinois to work at their research farm after graduating.

“In the middle of that, I figured out I wanted to go to grad school in weed science,” Loux said. After earning a Ph.D. from the University of Illinois, he took a position at The Ohio State University specializing in weed management.

“When I first started, we were still trying to just get control of a number of weeds because herbicide options were limited. The majority of our work was with the new herbicide candidates that were coming along,” Loux said. “Now, we really evaluate traits and whole systems. We have a lot of good traits and herbicides to control weeds, so it’s a matter of using them the right way with the right program and in the right system.”  

While many weeds are still effectively controlled, others are becoming more difficult.  

“Our focus is developing systems to control major problematic, herbicide-resistant weeds,” Loux explained, referencing Ohio’s troublesome ragweed, marestail and pigweed populations. “They are difficult weed species with complex biologies.”

Helping farmers prevent the spread of these herbicide-resistant weeds is one of his biggest goals. When he’s not writing articles or recording videos to post online, Loux is talking with farmers at county agronomy meetings, updating the Ohio, Indiana and Illinois Weed Control Guide and answering emails from growers asking for recommendations.

He credits the Ohio Soybean Council’s support as being essential to his mission to help farmers identify and manage problematic weeds before they cause yield losses.

“We use soybean checkoff funds to create educational materials we hand out at all kinds of meetings, including pesticide recertification classes in the winter. Over the past few years, we’ve probably distributed about 8,000 folders of weed management information that growers find really helpful.”

Anne Dorrance OSU Soybean Researcher Field Leader

Anne Dorrance

Professor Soybean Pathology, Host Resistance

Professor Anne Dorrance knew early in her career she wanted to find answers that would help growers improve their yields and bottom lines. With past experience in several different crops, she narrowed her research focus to soybeans upon joining the team at The Ohio State University in September 1997.

Originally from upstate New York, Dorrance was raised the granddaughter of a dairy farmer and the daughter of a college professor. She intertwined her roots in both agriculture and academia and now provides Ohio soybean farmers with innovative genetic solutions to control and prevent disease in their fields.

“In soybeans, the most effective way to fight disease is through genetics and resistance,” said Dorrance. “There is no need for farmers to utilize any further inputs and it is the most natural.”

Dorrance and her team at the Soybean Pathology Lab focus heavily on genetic improvement and the development of disease resistance in soybeans. She strives to provide growers with the best possible varieties for increased yields and maximized return on investment.

Throughout the summer, Dorrance spends several days a week out in the field observing her own data and working with students. She also assists crop consultants and county extension agents in troubleshooting severe pathogen problems as they arise on local farms.

When the growing season wraps up, Dorrance turns primarily to analyzing data and teaching classes like Field Crop Pathology. In addition to teaching, she advises graduate students, relaying her passion for developing disease-resistant soybeans to the next generation of researchers.

“My goal in life is to eliminate all soybean diseases,” said Dorrance.

Kelley Tilmon

Associate Professor, Department of Entomology, The Ohio State University

Entomologist Kelley Tilmon joined the faculty of The Ohio State University in 2016 after nearly a decade of serving as South Dakota State University’s soybean expert. Her lab’s approach is simple and practical:

“All our research is driven by what the farmers need,” said Tilmon.

These days, what Ohio soybean farmers need is advice on managing the brown marmorated stink bug. Its population has exploded in recent years, damaging soybean crops along the way.

Tilmon and her colleagues are working to develop more effective scouting techniques for soybean farmers. They’re still in the preliminary stages of adapting a method that has already seen success in fruit orchards: a plastic card coated with thick, sticky material and an irresistible insect pheromone designed to trap curious stink bugs.

Growers can count the number of insects collected and extrapolate that value into a general area population. Tilmon hopes that growers will eventually be able to use the cards in soybean fields across the state.

“It can save a lot of time when scouting insects,” said Tilmon. “Rather than literally beating all the bushes, farmers can let the stink bugs come to them.”

Another project on Tilmon’s radar pertains to good insects in the soybean fields, specifically, pollinators.

“Soybeans are self-pollinating, so we typically don’t think of pollinators as mattering that much,” said Tilmon. “But there are indications that having a good pollinator community in soybeans can provide a little bit of a yield advantage.”

With the help of local soybean growers who let OSU researchers use their fields for study, Tilmon’s team has been able to identify several dozen species that make up the soybean pollinator community. It’s not just the typical honeybee at work, but a wide variety of native bees and flies also playing a part.

For Tilmon, collaborating with farmers to make these discoveries is really the best part of the job.

“Ohio farmers are just fabulous and interesting and engaged with Ohio State research, and incredibly supportive of the work we do,” said Tilmon.

She appreciates the insight they provide to her own study and the forward-thinking attitude they have toward the industry of farming.

“I find that farmers are very receptive to my thoughts about what might be important in the future,” said Tilmon. “For example, one thing we’ve been concerned about is an invasive insect call the kudzu bug. It can cause huge damage to soybean production, and its range has expanded into Kentucky, which runs along our southern border. The Ohio Soybean Council has been funding us to run a monitoring program in southern Ohio to monitor for kudzu bugs and give us an early warning if it shows up in our state. Farmers are aware that they need to look to the future and fund research on it.”

Laura Lindsey, Ph.D.

Assistant Professor, Department of Horticulture and Crop Science, The Ohio State University

Laura Lindsey grew up in rural Ohio, the daughter of a middle school science teacher. It was her mother who first encouraged her to conduct experiments in areas like corn production and soil science for the science fair. It caught on.

Lindsey, Ph.D., is now Assistant Professor at the Ohio State University Department of Horticulture and Crop Science. She works with statewide corn, soy and wheat growers through the OSU extension office, helping to bridge up-to-date science and current farming methods.

Summers take her out into the field for outreach activities and educational workshops with farmers. These focus on practical matters for Ohio growers, such as how to increase soybean yield even as the area faces more sporadic rainfall and higher temperatures than ever before.

“A lot of our research focuses on things that improve the farmers’ profitability,” said Lindsey. “I get excited about all of it. I think soybeans are fascinating.”

One major recent project her group has undertaken: a revamping of the Ohio Agronomy Guide, its first in a decade. The Guide was first published in 1966, and this newest 15th edition will continue its history of helping growers understand the latest production trends and recommendations. The Guide is available for free on Lindsey’s extension website, Step Up Soy.

Lindsey remains in close touch with the farmers she meets, who have her email and cell number and know they can call her anytime with questions or ideas.

In Lindsey’s experience, Ohio farmers truly appreciate the OSU extension network and the access it provides to world-class researchers and grower resources like the Ohio Agronomy Guide. And really, it’s a two-way street.

“I think Extension and farmers have a pretty good both give-and-take relationship here. We learn a lot from farmers as well” said Lindsey. “We do on-farm research. Farmers are really helpful letting us have access to their fields and equipment. They give us a lot of ideas of things to look at.”

OSU Researcher Andy Michel

Andrew (Andy) Michel

Associate Professor and Interim Associate Chair, Department of Entomology, The Ohio State University

Andrew Michel grew up in the suburbs of Chicago, far away from any farmland. When he enrolled in Purdue University, he fell in love with entomology and the world of agriculture.

“It felt like a whole new world opened up to me outside of the suburbs, a whole new area of research possibilities,” said Michel.  

Michel is now an associate professor at The Ohio State University Department of Entomology and a member of the OSU Soybean Center team. He is interested in how insects adapt to environmental changes on a genetic level and how that information can help farmers use sustainable tools like resistant plants to adapt to the insects.

His lab has been keeping a particularly close eye on the invasion of new pests like the brown marmorated stink bug. In neighboring states like Pennsylvania, the infestations are so bad that people can be found sweeping them off their porches into five-gallon buckets.

“A colleague told me a story of a combine that caught fire. As it was harvesting soybeans, the intake valve got so clogged with brown marmorated stink bugs that it just killed the engine,” said Michel.

Ohio hasn’t seen those kind of populations yet. Michel and his colleagues want to make sure they never do and that farmers are ready to ward them off and protect their crops.

He goes out into the field regularly to help farmers learn to identify and scout for stink bugs and other pests. Interacting with growers is Michel’s favorite part of the job.

“I love getting out in the field and talking to growers to come up with real, practical solutions that can help them,” said Michel. “It helps put my recommendations in perspective as well. It’s easy for me to tell a grower to spray or not spray but, at the end of the day, it’s not my livelihood out in that field. It’s theirs.”

He tries to spread the message of give-and-take learning to the younger generation of scientists as well. During the summers, he hires students from the local liberal arts college in Wooster who have suburban or urban backgrounds.

“When we get out to a field, I can show them soybean plants that have aphids all over them,” he said. “They quickly realize that, yes, sometimes growers do need to spray. It’s not all about organic or not using pesticides.”

Michel cites the Ohio Soybean Council’s funding as vital to his work developing resources for farmers, including the recent soybean aphid genome sequence.
