Interpretive Summary: Leonian, a Biologist in New Mexico first described the plant pathogen infecting Chilli pepper and called it Phytophthora (death of roots) capsici (infecting Capsicum) in 1922. The current paper describes the important progress made and challenges faced over the past 100 years since this pathogen was first describe by Leonian. Since the Pathogen was described in 1922, over 800 publications have been written about this pathogen. At the close of 100 years of research, this paper briefly reviews the salient mile markers of the various discoveries made on the biology and management of this important plant pathogen which infects peppers, tomato, egg plant, watermelon, cucumber, squash, pumpkin, lima bean and various other vegetable crops. The information will be useful to University researchers and extension agents.

Technical Abstract: In 1922, Leonian, a former Assistant Biologist at the State Agricultural Experiment Station of the New Mexico College of Agriculture and Mechanic Arts, described a new pathogen infecting chile pepper (Capsicum annuum), which he named Phytophthora capsici. The account of this new pathosystem was limited to the description of the structures formed by P. capsici including sporangia, zoospores, tuberous mycelial outgrowths, and oospores, and the symptoms of infection observed on roots, leaves, and fruit of affected plants. Information on management of the new disease was scanty, and included seed selection and application of fungicides. Since 1922, P. capsici has been the subject of more than 800 publications including articles, abstracts, reviews, and book chapters on crop loss, host range and distribution, epidemiology, genetics, pathogenicity, host resistance and susceptibility, and management. At the close of 100 years of research, this article briefly reviews the salient mile markers of the various discoveries made on the biology and management of P. capsici.
