PM 7/110 (1) Xanthomonas spp. (Xanthomonas euvesicatoria, Xanthomonas gardneri, Xanthomonas perforans, Xanthomonas vesicatoria) causing bacterial spot of tomato and sweet pepper.

Abstract

This EPPO standard describes a diagnostic protocol for Xanthomonas spp. causing bacterial spot of tomato and sweet pepper (X. euvesicatoria, X. gardneri, X. perforans and X. vesicatoria). This procedure involves (i) detection in disease plants (symptomatic and asymptomatic) and seeds, and (ii) identification using at least two tests based on different biological principles (hypersensitive reaction, biochemical characteristics, serological, polymerase chain reaction and DNA fingerprinting/barcoding methods, as well as pathogenicity test).
