Abstract: Pear fruit and pear and apple seedlings trapped more Pythium spp. than the fruit of apple, lemon, and avocado, while few Phytophthora spp. were trapped in seedlings. Phytophthora spp. isolates were trapped most often in pear and apple fruit. Lemon and avocado fruit yielded a fair number of both genera.
