Marshmallow is an important medicinal plant in Serbia. Because of increasing demands on the market, cultivation has been started. Through regular quality control of commercial seeds and plantations, mycopopulation of marshmallow was recorded in the period 2000-2006. Seeds of marshmallow were dominated by Alternaria alternata and species from the genus Fusarium (Fusarium verticillioides, F. proliferatum, F. semitectum, F. oxysporum and F. solani). Species belonging to Fusarium genus are the cause of rot of seeds and roots of marshmallow, causing chlorosis and fading, and therefore deterioration and necrosis of plants, as well as decrease of seed germination of seeds. Leaves and stalks of marshmallow were from time to time under massive attack of Puccinia malvacearum, and that was the reason why leaves were unuseful as a herbal drug. On roots and lower part of the stalks, massive appearance of Sclerotinia sclerotiorum, a causal agent of the white rot, in cases when marshmallow was cultivated after sunflower, was recorded, too. From other fungi in roots, species belonging to the genus Fusarium (F. oxysporum, F. solani and F. verticillioides) were dominant.
