Abstract
Investigation has shown that Rosellinia necatrix Prill. and Roesleria pallida (Pers.) Sacc. root rot fungi remain infective on root in soil for several years.
They affect the rootlets, causing decay of the root system and wilting of the tree.
These fungi endanger greatly the young plants in replanted orchards and vineyards.
It is suggested that soil investigations for replant disease should cover also a survey of root rot fungi.
The frequent and heavy occurance of these fungi where replant-diseases are observed shows a close connection to these disorders.

The frequent and heavy occurance of these fungi where replant-diseases are observed shows a close connection to these disorders.
Fungicides used against them were not effective but harmed the useful microorganisms, hyperparasites and mycorrhizal fungi. Entoloma clypeatum (L.Fr.) Kummer entomycorrhiza fungus reduces the effects of these root rot fungi on the Prunus species.
