Abstract
The obligate fungi inside the family Albuginaceae are widespread world wide and cause white rust or white blister disease. Mycopopulation of weeds has been researched within the project „The role of weeds in epidemiology of row-crop diseases“. The aim of this research was to identify white blister species occurring on weeds in Eastern Croatia. Weed plants with disease symptoms characteristic for white blister species have been collected since 2001 on location Slavonia and Baranja country. Determination of white blister species was based on morphological characters of pathogen and the host. Wilsoniana bliti was determined on Amaranthus retroflexus and Amaranthus hybridus leaves. Capsella bursa pastoris is a host for Albugo candida. Ambrosia artemisiifolia is a host for Pustula sp. and Cirsium arvense was found to be host for Pustula spinulosa. Wilsoniana portulaceae was determined on Portulaca oleracea.Gljive iz porodice Albuginaceae utvrđene su diljem svijeta i uzrokuju bolesti poznate pod imenom bijela hrđa. U okviru projekta „Uloga korova u epidemiologiji bolesti okopavinskih kultura“ proučava se mikopopulacija korova, a cilj ovoga rada bio je proučiti Albugo vrste koje se javljaju na korovima u istočnoj Hrvatskoj. Korovi sa simptomima bolesti karakterističnim za bijelu hrđu prikupljani su od 2001. godine na lokacijama Slavonije i Baranje. Determinacija uzročnika bijele hrđe temeljila se na morfološkim karakteristikama patogena i domaćinu. S lišća Amaranthus retroflexus i Amaranthus hybridus izoliran je Wilsoniana bliti. Capsella bursa pastoris je domaćin za Albugo candida. Ambrosia artemisiifolia je domaćin za Pustula sp., Cirsium arvense za Pustula spinulosa, a Wilsoniana portulacae izolirana je s Portulaca oleracea
