Evaluation of Mustard Plant Extracts to Reduce Spore Germination of Pathogenic Fungi, Fusarium oxysporum in Soybean Fields.
Fusarium is a genus of fungi that includes many pathogenic species that infect important agricultural crops such as soybeans. Many soybean farmers in Missouri grow cover crops between soybean growing seasons to prevent soil erosion, introduce nitrogen into the soil, and reduce weed growth. Mustard is a common cover crop used in the US. The objective of this study is to evaluate different mustard varieties for their ability to reduce disease incidence of three pathogenic Fusarium species. Mustard extracts were tested against 3 Fusarium species growing on potato dextrose medium. Fungi spore germination and vegetative growth were evaluated 2, 4, 6, and 7 days after inoculation. Mighty Mustard, Cal-199, Cal Rojo, & Wasabina mustard varieties decreased the fungal vegetative growth and spore germination, whereas Yellow Mustard did not show any inhibitory effects. Crimson clover, a commonly used cover crop, increased fungal vegetative growth and spore germination.
