Abstract: This disclosure relates to methods of controlling Erwinia amylovora with natural and synthetically-produced vinylglycines and variants thereof. As Erwinia amylovora is the causal agent of the plant disease fire blight, by extension, this disclosure relates to methods of controlling fire blight with vinylglycines and variants thereof. This disclosure also relates to methods of controlling Erwinia amylovora, and by extension, fire blight, with vinylglycine-producing bacteria.

Abstract: The present disclosure concerns specific herbicide molecules, herbicidal compositions comprising the molecules and the bacterial strains that produce certain of these molecules, and methods of using these molecules and bacterial strains to control grassy weeds and other sensitive weed species.
