Do We Really Understand Crown Gall Control by AgrobacteriumRadiobacter Strain K84?
Control of crown gall disease by Agrobacterium radiobacter strain K84 has been commercially available for 15 years. Where it works, it works quite well. Where it does not work, it generally fails completely. In part, this mirrors the phenomenology of the biocontrol field. The difference is that with the K84 system we have some appreciation for how the organism controls the disease, and, perhaps even more importantly, why it may fail to do so. Our purpose here is to critically examine what is known about the system, to indicate current directions for research in the system, and, using the results generated by such research, to describe directions being taken to improve the system.
