摘要

Michigan has over 82,000 acres of vegetables that are susceptible to the soil-borne oomy-cete pathogen Phytophthora capsici. The pathogen may overwinter in the soil and persist for many years (>10 years). The roots, crowns, stems, leaves and fruits ofpeppers can all be infected by P. capsici. This pathogen is favored by rain and warm temperatures and spreads readily via water. P. capsici has been found in irrigation ponds and surface water sources.
