Bacillus velezensis strain MBY2, a potential agent for the management of crown gall disease.

The reduction of the use chemical pesticides in agriculture is gaining importance as an objective of decision-makers in both politics and economics. Consequently, the development of technically efficient and economically affordable alternatives as, e.g., biological control agents or practices is hig...
