Results of experiments with isolates A1 and A2 from populations occurring in Poland in the years 1993-1998 were compared. Mating types A1 and A2 did not significantly differ with respect of virulence spectrum, pathogenicity level and virulence diversity (Shannon index). After pairing isolates A1 and A2 formed oospores; their morphological characteristics were described. On selected fields a test was performed whether the oospores could play a role as a source of primary infection. Local populations occurring on three fields were characterized. Results obtained on investigated 3 separate fields, located in 2 voivodeships of southern Poland were compared. It was stated on the basis of the proportion of both mating type isolates, race complexity and diversity, that oospores could play a role as a source of primary infection, at least in one of localities in Boguchwała, podkarpackie voivodeship.

Measurements of spectral reflectance from potato plants were carried out in the years 2000 and 2001 using the field radiometer CE 313 of Cimel Electronique Company. Field experiments permitted to perceive differences in the reflectance of electromagnetic radiation from potato plant cultivars Bekas and Mila as well as differences between the plants treated with fungicides providing the protection against Phytophthora infestans and the untreated plants. A differentiation of the values of vegetative indices between potato cultivars resulted from the unequal development rate of the cultivars and from their different susceptibility to Phytophthora infestans. The assessment of potato plants infection by the studied pathogen using spectral measurements agreed with the results of field inspection.
