The Ohio State University Seed Pathology Seed pathogens represent a major loss in production of quality seeds and stand establishment.
Losses occur during seed development, storage, and planting.
Methods to control seed and seedborne pathogens have historically relied on chemical applications to the seed. Increasing governmental restrictions on pesticide use, however, may cause a shift to natural biological agents to control pathogens. Today, an entire industry has emerged to manufacture chemical control products. These pathogens, however, still constantly change in response to pesticides and adapt to biological control measures. Moreover, as international trade of seed increases, there will be an increasing concern about the movement of seedborne pathogens across international boundaries.
