Journal Title: Analele Stiintifice ale Universitatii Alexandru Ioan Cuza din Iasi, Serie noua, Sectiunea II a. Biologie vegetala - Year 2008, Vol 54, Issue 1
Abstract
Ulocladium atrum Preuss is a promising candidate as biological control agent against Botrytis cinerea Pers. from different plants: onion, lily, geranium, cyclamen, kiwifruit, strawberry, grapevine, etc. During year 2000 the authors have been worked together in the Plant Research International Wageningen, The Netherlands, for the EU project 1898 - BIOSPORSUPPRESS - The biological control of air-borne necrotrophic plant pathogens by suppression of spore production -, leaded by PhD J. Köhl. The objectives of that research were: (1) Testing culture media for Ulocladium atrum (isolate 385 and isolates from soil organic fragments and necrotic leaf fragments) in order to select the most favourable one for detecting the fungus in soil organic material and necrotic leaf samples; (2) Detecting of U. atrum incidence in necrotic leaf and soil samples (soil organic fragments‚ soil suspensions) collected from U. atrum treated strawberry fields plated on ARSA medium and (3) Reisolation and purification of U. atrum from colonies developing on organic material or soil dilution plates from all the experimental plots, obtaining of U. atrum isolates for their characterization in comparaison with the isolate 385 used in the experimental field plots as a biocontrol agent against the grey mould of strawberry.
