Abstract

Agrobacterium vitis causes a crown gall disease in grapevine and that is one of the major hindrances for the wide cultivation and production of grapevine. We studied the possibility of biological control using selected biological control agent. One isolate from the infected soil, named as strain 27, was able to inhibit the biovar 1; A. tumefaciens C58 and Ach5, biovar 2; A. rhizogenes 13264, and biovar 3; A. vitis, in vitro and in vivo test. The putative biological control agent, A. radiobacter strain 27 was carrying the plasmid and the size of isolated plasmid was very similar to that of pAgK84 of A. radiobacter K84.
