Invisible Pest Management

In today’s episode we explore how nematodes might be impacting your crop without you even knowing it. These microscopic worms are everywhere; they are the most abundant multicellular organism on the planet. But often, they go completely unnoticed because they can’t be seen without a microscope. What we most often see in agriculture is their impact on crops. Whether you grow row crops like soybeans, specialty crops like vegetables, or permanent crops like grapes, it’s important to know your nematodes. Corteva nematologist Dr. Tim Thoden discusses his work both from the perspective of someone fascinated with nematodes, and someone who acknowledges the enormous impact they can have on farmers.  “It is believed that the damage that nematodes globally do is around $120 billion to $150 billion US dollars per year…it's a huge economic damage.” - Tim Thoden, Ph.D.California raisin grape grower Michael Logoluso has seen the impacts of nematodes for the past three decades. He is a farm manager for Lion Farms which is a large grower and packer of dried-on-the-vine California raisins.“We need a few tools in our toolbox, right? So Salibro would be one of them…I think going forward it's going to make the other tools that we have available at this current time have a little more life on the shelf.” - Michael LogolusoLogoluso and Thoden discuss the economic impact of nematodes, modern agricultural practices for managing these microscopic pests, and the development of new solutions like Corteva's Reklemel, a synthetic nematicide sold under the name Salibro. They cover the complexities of nematode management, the role of healthy soils, and integrated pest management strategies while emphasizing the need for continuous innovation and respectful treatment of the environment.Some takeaways from this episode include: The sheer volume of these organisms. They are the most abundant multicellular organism on the planet, and three out of every four multicellular organisms are nematodes. The fact that scientists are not only looking for effective solutions, but targeted solutions that don’t hurt soil biology. This emphasizes the need for products that are intended to fit into an integrated approach by being effective against pests but not taking away from soil health. How much these organisms fly under the radar because they can’t be seen by the naked eye. The pest might be invisible without a microscope, but the devastation they can cause is very real.Agriscience Explained is a podcast brought to you by Corteva Agriscience. Host Tim Hammerich visits with both scientists and farmers about how agricultural innovations are discovered, developed and deployed on the farm.
