Biodiversity of Plant Pathogenic Fungi - Kerala Forest Research ...

were found widely distributed and caused diseases in altogether 396 and 220 host species
respectively in the Western Ghats. Nine species of Cylindrocladium were found causing
diseases in different host plants and the fungal genus was found distributed in all the
ecosystems studied (Fig. 5). Similarly, Phomopsis sp. was found widely distributed in the
different ecosystems and caused foliage diseases in about 222 host species. The fungus
was found widely distributed in the moist deciduous forests causing diseases in about 124
host plants (Fig. 6). Data on the selected major fungal pathogens are given in Figure 7.
