Wilting of the lower leaves occurs at warm temperatures [25–28ºC (77–82ºF)] and the leaves recover under cooler temperatures. Genetic diversity and biocontrol efficacy of indigenous Trichoderma isolates against Fusarium wilt of pepper Omar A. Hewedy. The application of the nonpathogenic isolate Fusarium oxysporum 47 (Fo47) reduced the symptoms of verticillium wilt, phytophthora root rot and phytophthora blight in pepper plants.Botrytis cinerea was also tested on the leaves of plants treated with Fo47, but no protection was observed.Verticillium dahliae colonies … 1d).
