Based on our investigations, the following conclusion was drawn:
-The pathogen of Phytophthora parasitica var. nicotianae is present in severel tobacco producing regions in R. Macedonia (Prilep, Kumanovo, Strumica).
-This is a soilborne pathogen which infects the root and the aboveground part of tobacco stalk, and during periods of rainy weather, the lower leaves of the plant may also be infected.
-The mycelium develops in tobacco plant tissues, where it stays after the end of its growing period.
-The fungus owerwinters in a form of chlamydospores in the plant debris, and when favorable conditions appear, the chlamydospores germinate into hyphae
or sporangia, which make the primary infections.
-The pathogen is spread by the infected plant debris, by infested soil, irrigation water, farm equipment and by root nematodes.
-To prevent the occurrence and distribution of the disease it is necessary to apply crop rotation, adequate cultural practices, resistant tobacco varietes, nematodes control and chemical protection.
-Of the investigated in vitro and in vivo applied chemicals, the highest effect was obtaind with application of the metalaxyl-based fungicide Ridomil MZ72.
