SUMMARY Isolates of Phytophthora palmivora from various countries were compared for compatibility in oospore production with standard isolates of the ‘rubber’ and ‘cocoa’ groups. It was found that most of the isolates belonged to the ‘cocoa’ group, one to the ‘rubber’ group, and three did not form oospores under any circumstances. The isolates showed different growth rates in wound‐inoculated pod tissue. Individual isolates showed different growth rates on pods of two varieties of cocoa.
