Causal agents of root and stem base rot of wheat

Abstract

During the 2004/05 growing season, plant deterioration was recorded at various stages of wheat crop development in the following locations: Rimski Šančevi, Kać, Kikinda, Zrenjanin, Pančevo, Kovin, Smederevo, and Smederevska Palanka. Plant samples were collected and used for pathogen identification. The results showed that the main causal organisms responsible for the outbreak of root and stem base rot in wheat were fungi of the genus Fusarium. At the Rimski Šančevi location, of the 1,308 plants of the wheat cultivar Zlatko that were subjected to analysis, 722 (55.2%) had root rot caused by fungi of the genus Fusarium, 14 (1.1%) had roots deteriorated by the fungus Gaeumannomyces graminis, while only 9 (0.7%) had symptoms typical of the causal agent of foot rot, Pseudocercosporella herpotrichoides.

U proizvodnoj 2004/05. godini na više lokaliteta: Rimski Šančevi, Kać Kikinda, Zrenjanin, Pančevo, Kovin, Smederevo, Smederevska Palanka zabeleženo je propadanje biljaka u različitim fenofazama razvoja useva pšenice. Na prikupljenim uzorcima vršena je identifikacija patogena. Rezultati analize pokazali su da su glavni uzroci truleži korena i prizemnog dela stabla pšenice bile gljive iz roda Fusarium. Od 1308 analiziranih biljaka sorte Zlataka, kod 722 (55,2%) su prouzrokovač i truleži korena bile gljive iz roda Fusarium, kod 14 (1,1%) biljaka uzrok propadanja korena bila je gljiva Gaeumannomyces graminis, svega 9 (0,7%) analiziranih biljaka bilo je sa simptomima proouzrokovača sočivaste pegavosti Pseudocercosporella herpotrichoides.
