Fungi isolated from soil before the seeding and after harvest of pea (Pisum sativum L.) after application of bio-control product EM 1 TM

Abstract

A field experiment was performed during the years 2003- -2005. An influence of EM (Effective Microorganisms) on the composition and number of fungi isolated from soil was found in the experiment. A total of 18111 fungal cultures were isolated from the roots of pea at flowering stage. The highest amount and the lowest diversity of fungi were obtained from rhizosphere of pea treated with pesticides (3257 colonies). The greatest diversity of fungi was found in the case of rhizosphere and rhizoplane, where EM was used in soil with the supplement of pesticides. The greatest amount and diversity of fungi were found from the plant roots of the control object. During the flowering stage, the fungi most frequently isolated from soil belonged to the genus Penicillium (40.78% of all isolates) and Fusarium (33.37% of all isolates).
