In 2017-2020 in the conditions of Kirov region there were studied 143 varieties, 115 perspective lines and 28 hybrids first generation spring soft wheat according to degree resistance septoria tritici blotch against background natural development infection. It has been established that disease significantly increased with a decrease air temperature during «seedling-tillering» phase (r = -0.83…-...

The genus Septoria includes important plant pathogens with worldwide distribution, commonly associated with leaf spots and stem cankers of a broad range of plant hosts. In this study, eight isolates of Septoria were recovered from leaves with leaf spot on four herbaceous and woody plants from Gilan, Ardebil, East and West Azerbaijan provinces in north and northwest of Iran. The isolates were st...

The mechanism leading to vector competence of thrips species to transmit tomato spotted wilt virus (TSWV) is not well characterized. We investigated the interaction of TSWV and the non-vector species Frankliniella tritici. A monoclonal antibody to the non-structural protein (NSs) of the TSWV was used to detect TSWV replication within the thrips by immunofluorescence microscopy and enzyme-linked...

Rathayibacter tritici, which is a Gram positive, plant pathogenic, non-motile, and rod-shaped bacterium, causes spike blight in wheat and barley. For successful pathogenesis, R. tritici is associated with Anguina tritici, a nematode, which produces seed galls (ear cockles) in certain plant varieties and facilitates spread of infection. Despite significant efforts, little research is available o...
