Significant bean bacteriosis

Abstract

Beans are an important plant species that is grown in our agroecological conditions. One of the significant 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.
