Didymella applanata: Causal agent of raspberry spur blight

Abstract

Raspberry spur blight, caused by Didymella applanta, poses a serious problem in the production of this most significant berry fruit in Serbia. Success in the prevention of the disease occurrence and development depends mainly on the biology of the pathogen, disease epidemiology and the relationship between the parasite and the host plant. The use of control measures that prevent damages is based on the comprehensive knowledge of all factors contributing to the disease development. Present knowledge about the causal agent, and its morphological, ecological and epidemiological characteristics are systematized in the paper. Infection process, symptom development, as well as the control possibilities of this phytopathogenic fungus, are thoroughly discussed.

Kestenjasta pegavost izdanaka maline, koju prouzrokuje fitopatogena gljiva Didymella applanata, predstavlja veliki problem u proizvodnji ove najznačajnije jagodaste voćke u Srbiji. Uspeh u sprečavanju pojave i razvoja oboljenja pre svega zavisi od biologije patogena, epidemiologije bolesti i odnosa parazit i biljka-domaćin. Samo na osnovu dobrog poznavanja svih činilaca koji utiču na razvoj oboljenja moguće je primeniti mere suzbijanja kojima se sprečavaju štete. U radu su sistematizovana dosadašnja saznanja o prouzrokovaču oboljenja, njegovim morfološkim, ekološkim i epidemiološkim karakteristikama. Detaljno su opisani razvoj simptoma oboljenja, kao i mogućnost suzbijanja ove fitiopatogene gljive.
