Bacterial and phytoplasma diseases of raspberry and blackberry

Abstract

Raspberry and blackberry production, processing and export are main sources of incomes for the majority of farmers in particular areas of Serbia. However, profitability of the production is often compromised by disease outbreaks. Compared to fungal diseases, bacterial diseases are of less importance, but in years with favorable weather conditions can cause serious damage. This paper describes major bacterial diseases on raspberry and blackberry, such as bacterial blight caused by Pseudomonas syringae, crown gall caused by Agrobacterium tumefaciens and fire blight caused by Erwinia amylovora described as a pathogen of raspberry in North America. Beside bacteria, phytoplasmas can also be associated with raspberry and blackberry. The aim of this paper is to provide the knowledge about symptomatology and epidemiology of bacterial and phytoplasma diseases of raspberry and blackberry in order to facilitate accurate and timely diagnosis and adequate control strategy.

Proizvodnja, prerada i izvoz maline i kupine su u pojedinim regionima naše zemlje glavni izvor prihoda za većinu stanovništva. Međutim, profitabilnost proizvodnje često umanjuje pojava bolesti. U poređenju sa gljivičnim oboljenjima, bakterioze imaju manji značaj, ali pri vremenskim uslovima pogodnim za razvoj bolesti, mogu naneti ozbiljne štete. U radu su predstavljene najznačajnije bakterioze maline i kupine kao što su bakteriozna plamenjača, čiji je prouzrokovač Pseudomonas syringae, bakteriozni rak korena i izdanka, prouzrokovan bakterijom Agrobacterium tumefaciens, kao i bakteriozna plamenjača jabučastih voćaka prouzrokovana vrstom Erwinia amylovora, koja je opisana kao patogen maline u severnoj Americi. Osim bakterija, malinu i kupinu mogu parazitirati i fitoplazme. Cilj rada je da doprinese poznavanju simptomatologije i epidemiologije bakterioznih i fitoplazmoznih oboljenja maline i kupine, kako bi se postavila pravilna i pravovremena dijagnoza i preduzele adekvatne mere zaštite.
