Interpretive Summary: Phytophthora capsici is a plant pathogen that can infect vegetable, ornamental, and tropical crops. It has spread across the globe, and can infect more than 200 species of plants including many popular vegetables including tomatoes, peppers, cucumbers, pumpkins and watermelon. First identified and described in 1922, this review details the research and advancements that have made over the past 100 years on its biology and management.

Technical Abstract: Phytophthora capsici is a destructive oomycete pathogen of vegetable, ornamental, and tropical crops. First described by L. H. Leonian in 1922 as a pathogen of pepper in New Mexico, United States, P. capsici is now widespread in temperate and tropical countries alike. Phytophthora capsici is notorious for its capability to evade disease management strategies. High genetic diversity allows P. capsici populations to overcome fungicides and host resistance, the formation of oospores results in long-term persistence in soils, zoospore differentiation in the presence of water increases epidemic potential, and a broad host range maximizes economic losses and limits the effectiveness of crop rotation. The severity of disease caused by P. capsici and management challenges have led to numerous research efforts in the past 100 years. Here, we discuss recent findings regarding the biology, genetic diversity, disease management, fungicide resistance, host resistance, genomics, and effector biology of P. capsici.
