Abstract

O crestamento bacteriano comum do feijoeiro causado por sobrevivência e disseminação da Xap, a semente representa o mais Xanthomonas axonopodis pv. phaseoli (Xap) é a principal doença eficiente.

Even though this pathogen is disseminated in all production state of Paraná during 1998/99 and 1999 were evaluated to the presence regions of the country, it has caused major damages in the states of of Xap in seed macerates plated on a semi-selective culture medium.
