Abstract: The forest seedling material production faces the major problem of the investigators of plant diseases, most notably the phytopathogenic fungi which causes the deseases of lodging of saplings. Their massive emergence is due to the fact that the production takes place in the open space where the sapling, during the period in which it is the most sensitive, is exposed to the numerous harmful abiotic factors, that are favourable to the development of pathogen, such as: Fusarium spp., Botrytis spp., Rhizoctonia spp. and Penicillium spp. The appropriate protection of saplings in the hothouses in the open space can be performed by applying the certain types of fungicides, specific effect of which is determined by the presence of the active substance. Active ingradient which have fungicide effect and fall into the group of benomyl, ditiocarbamates, strbylirines, and triazol have the stisfactory results in the preliminary experimental investigations of the efficacy of the fungicides belonging to the aforementioned groups. Nevertheless, the current legal regulation forbids the circulation of pesticides which are not permitted to be used for elimination of certain pathogens on certain host plant. Theredore, if the preparation has not been registered for the use on the forest plant species, it cannot be used for protection. Due to the fact, there is a problem in Serbia as the producers of pesticides are not willing to register their products in forestry, since there is a small market demand for them. The strategy that we suggest refers to the selection of active substances and preparations which can be used in the forest hothouses. We also recomended the producers and beneficial owners of pesticides to investigate the effect of their products, in order to reister them in the category of small crops, in which the forest hothouses belong. In this way, with the respect of the legislation, the control of pathogens which cause the loding of saplings can be well-performed.
