​The soil fumigant metam sodium continues to be important in managing soilborne pests of potato such as Verticillium dahliae, the primary cause of early dying, and the root lesion nematode (Pratylenchus penetrans). Recent label changes resulting from the reregistration of metam sodium by the EPA have made the application of the fumigant through water applications very difficult due to the requirement of large buffer zones to reduce human and animal exposure to the chemical. As a result, there has been a dramatic increase in the application of metam sodium via shank injection, which is not as efficacious as water applications. This presentation will discuss the most recent research conducted at North Dakota State University on improving the efficacy of shank injection of metam sodium.

Neil C. GudmestadNeil C. Gudmestad obtained a PhD in plant pathology in 1982 and joined the Department of Plant Pathology at North Dakota State University in 1985. His research career at NDSU has focused on pathogen biology and diversity and on potato disease management. He has made significant research contributions on potato diseases caused by 10 fungal or fungal-like organisms, four viruses, and three bacteria. Most recently, he has focused on invasive pathogens affecting the potato industry in the United States, such as zebra chip and potato mop top. All of his efforts are aimed at solving real-world problems facing the potato industry.​
