Since the early 1990s, Ivan Wollenmann has been working with growers, co-ops and input companies to match solutions to need, according to a news release from the company. It will add his expertise to its team of experienced sales professionals as its new Regional Manager, Midwest.

In the new role, Wollenmann will be responsible for sales and marketing of the biopesticide leader’s extensive product line across midwestern states and into a diverse array of crop categories, according to the release. He will be based in Noblesville, Indiana.

Headquartered in Columbia, Maryland, Certis USA manufactures and distributes a broad line of biopesticide products for specialty agricultural and horticultural markets, as well as the home and garden market.

“We are seeing a tremendous amount of growth opportunity for biologicals into crops that have previously relied on synthetic chemistries and much of that trajectory falls in the Midwestern U.S.,” Certis USA’s Scott Peterson, national sales director, U.S. Ag, said in the news release. “Ivan’s vast network from his long career serving the input needs of growers will deliver a new set of solutions to these growers and continue serving the needs of our existing customers in the region.”

Wollenmann’s expertise was garnered through recent positions with SUL4R-PLUS and KOCH Agronomic Services where he introduced to the market two new nitrogen stabilizer products, according to the release. In positions with WinField United and LG Seeds, Wollenmann honed his skills in providing input solutions to growers and managing supply relationships with channel partners.

“I have spent my career in input specialties and have watched as the biologicals industry has skyrocketed, thanks in part to the pioneering leadership of Certis USA,” Wollenmann said in the release. “Being a part of that leadership now will give me more opportunity to help growers in the Midwest succeed in their businesses and livelihoods.”
