The plant pathogens as Alternaria solani, Monilinia fructigena, Botrytis cinereae and Venturia inaequalis cause significant damages on many plants in the European region (particularly in the region of Republic of Bulgaria), especially on orchard cultures which are very important for agricultural industry in this area. There is many existed commercial plant protection products towards this phytopathogens on the market and there is intensive pesticides treatments in order to be overtake infestations and damaging of the plants from this pathogenic fungus. However such king pesticides in the most cases are toxic and harmful for the humans and environment, so there is a need for development and introduction on the pesticide market of the novel environmentally friendly plant protection products against these diseases. In the present research paper an in vitro trials were conducted with ethanol extracts from tarbush plant (Flourensia cernua) with conidial sporulation of of Alternaria solani, Monilinia fructigena, Botrytis cinereae and Venturia inaequalis. The received results show the strong antisporulation action of tarbush plant ethanol extracts towards tested pathogens. However according to the conidiospores of Alternaria solani, there was full lack of effectiveness and even slightly stimulation action of germination of spores. This results can be a base for development of the new natural fungicides against tested plant pathogens wicth can be apllied as in the commersial agriculture, as in the organic or integrated pest management
