Ekonomski najznačajnije bakterioze pasulja

Abstract

Jedan od činilaca smanjenja prinosa i kvaliteta pasulja su fi topatogene bakterije koje prouzrokuju simptome na listovima, stablu, mahunama i semenu. Takođe, jedan od razloga učestale pojave bakterioza pasulja je upotreba nedeklarisanog zaraženog semena. U agroekološkim uslovima Srbije u povoljnim godinama za razvoj bolesti na pasulju su najzastupljenije vrste fi topatogenih bakterija iz rodova Xanthomonas i Pseudomonas. Vrsti Xanthomonas axonopodis pv. phaseoli prouzrokovaču obične bakteriozne plamenjače pogoduju topliji i vlažniji uslovi, dok za pojavu i širenje vrste Pseudomonas savastanoi pv. phaseolicola odgovara hladnije vreme i vlažni uslovi.

Beans are an important plant species that is grown in our agroecological conditions. One of the signifi cant factors in the reduction and quality of yield are phytopathogenic bacteria that appear on leaves, stems, pods and seeds. Also, one of the reasons for the frequent incidence of the disease is the use of seeds that are not declared, and very often infected. In our conditions, depending on the environmental conditions, two species from the genus Xanthomonas and Pseudomonas predominantly appear. Species Xanthomonas axonopodis pv. phaseoli, the causal agent of common bacterial blight is affected by warmer and wet conditions, while the species Pseudomonas savastanoi pv. phaseolicola is affected by colder weather and humid conditions. Other bacteria that appear are of minor economic importance.
