Project description
Esca is ‘n wingerdsiekte wat bestaan uit ‘n kompleks van patogene, naamlik Phaeomoniella chlamydospora, Pheaoacremonium spp. en Basidiomycete swamme (houtverrottingswamme) (Mugnai et al., 1999). Voorheen is aanvaar dat Stereum hirsitum en Phellinus igniarius die veroorsakende organismes in Suid-Afrikaanse wingerde is (Marais, 1981), alhoewel geen navorsing ooit in hierdie verband uitgevoer is nie. Aangesien die blaarsimptome relatief skaars is in plaaslike wingerde, is die aanname ook verkeerdelik gemaak dat esca nie baie algemeen voorkom nie. Verskillende houtverrottingswamme skei verskillende toksiene af en gevolglik kan dit blaarsimptome beïnvloed (Sparapano et al., 2000; Tabacchi et al., 2000). Daarom is dit belangrik dat die kombinasie van swamme in die esca-kompleks ondersoek word. Houtverrottingswamme kan produksie geweldig beïnvloed en kan die leeftyd van ‘n wingerd drasties verkort. Dit het ook ‘n direkte invloed op die kwaliteit van wyn wat gemaak word van ge-affekteerde stokke. Kennis van die veroorsakende organismes en hul infeksieweg sal direk daartoe bydra dat oordeelkundige beheerstrategië geïmplementeer kan word.
