 The essential oils of six aromatic herb species and inter-species hybrids from the lamyaceae family, including chocolate mint, pineapple mint, apple mint, spearmint, orange mint, and strawberry mint, were investigated for their antimicrobial effects against plant pathogenic bacteria such as agrobacterium tumifatians, pseudomonas syringi pv, syringi, and xanthomatosarbarycola pv. Corillina. The screening was conducted in vitro on agar plates filled with the target organism. All essential oils exhibited a higher level of antibacterial activity against the tumifatians and exarbarycola pv. Corillina then streptomycin used as a standard in all tests. The antimicrobial effect of streptomycin and five mint oils was at the same level for psyringi pv. Syringi. There were no significant differences in the influence of chocolate mint oil on the growth inhibition of all bacteria tested. Pineapple mint, apple mint, spearmint, and strawberry mint essential oils showed the weakest antibacterial activity against psyringi pv. Syringi and the strongest towards the tumifatians and exarbarycola pv. Corillina. The essential oils from strawberry mint, pineapple mint, spearmint, and apple mint had the strongest effect on the tumifatians, while the lowest inhibitory activity was exhibited by chocolate mint and orange mint essential oils. Exarbarycola pv. Corillina was the most sensitive to the strawberry mint, pineapple mint, and spearmint oils. The chocolate mint oils showed the greatest activity against psyringi pv. Syringi.
