Phytophthora blight, caused by Phytophthora capsici , is a widespread problem of many vegetables including bell peppers. Four bell pepper cultivars marketed as resistant/tolerant to P. capsici include `Paladin' (resistant), `Alliance' (tolerant), `Aristotle X3R' (tolerant), and `Revolution' (tolerant). These cultivars, along with four other widely grown cultivars (`Commandant', `King Arthur', `Legionnaire', and `Red Knight X3R') and a susceptible control (`California Wonder'), were evaluated for their performance in a commercial field highly infested with P. capsici . `Paladin' had the lowest incidence of Phytophthora blight and the greatest yield compared to all other cultivars. `Alliance', `Aristotle X3R', and `Revolution' (the tolerant cultivars) also had lower Phytophthora blight incidence and greater yields compared to the other five cultivars evaluated. Results indicated that in fields that historically have high incidence of Phytophthora blight, `Paladin' could be a reliable choice for commercial production.
