Abstract
Based on literature, a potential range distribution for P. omnivorum has been developed using edaphic factors. Soil base exchange capacity, pH, Na and Ca contents and clay fraction were factors delimiting occurrence and survival of the fungus. A nonedaphic factor considered was mean annual air temperature. Soil types possessing the necessary characteristics were identified using the FAO-UNESCO soil-classification system. A map of the potential distribution of P. omnivorum in North America was produced and a comparison made with the known distribution of Phymatotrichum root rot disease. The 2 distributions were coterminous. Distribution of P. omnivorum-conducive soils in South America, Africa and India was also examined.This publication has 0 references indexed in Scilit:
