2003 m. Nr. 4 The biodiversity of fungi parasitizing weeds in Lithuania
Species composition of fungi
parasitizing weeds in Lithuania was ascertained with a particular reference to
biocontrol. The disease distribution and severity were evaluated. Over the
years of investigations (1995–2002), 34 fungal species were identified on 17
weed species. The most widespread in Lithuania were Septoria polygonorum, Monodidymaria
chenopodii, Ramularia inaequale, R. cynarea, Puccinia taraxaci, and
P. punctiformis. Leaf-spotting disease agents – Septoria convolvuli, S.
polygonorum, Monodidymaria chenopodii, Ramularia inaequale and rusts – Puccinia
punctiformi, P. absinthii showed high aggressiveness to host (the area of affected
leaves reached 75–90%). Some strains of pathogenic fungi were isolated into
pure culture for the experiments on biological peculiarities and effect on host
fitness. This is the first step of a detailed investigation on mycobiota of weeds
in Lithuania.
