The antimicrobial activity of 20 10% (v/v) solutions in ethanol of terpenes and terpenoids at several concentrations was tested against Erwinia amylovora NCPPB 595 in the liquid medium 523. The test organism responded differently to the chemicals. At 600, 900 and 1200 mg/l, none of the compounds reduced the growth of the bacterium. At 1500 mg/l, only some of the chemicals significantly inhibited growth x ‐Pinene. β‐terpinene, dihydrocarveol, isopulegol and linalool reduced growth of suspensions of 1 × 10 3 cfu/ml, whereas β‐pinene was more effective when challenged with larger numbers of cells (i.e. 1 × 10 5 cfu/ml and 1 × 10 7 cfu/ml). At 1500 mg/l, geraniol and citronellol exerted a bactericidal activity regardless of the concentrations of the test organism.
