The Lamiaceae family contains important aromatic plants used in traditional and modern medicine and in food and pharmaceutical industries. Plants belonging to this family are mostly exploited for the extraction of essential oils (EOs). The genus Monarda L. includes about eighteen species of herbaceous, annual or perennial plants endemic of North America. Several biological activities have been reported for plant EOs and their main components, including a biocidal activity against plant soilborne pathogens and pests, which also includes plant-parasitic nematodes [1]. The EOs can play an important role in crop protection and have been propose as an environmentally alternative to synthetic pesticides. In this study, the EOs from two Italian species of Monarda (M. dydima and M. fistulosa) were evaluated for their in vitro activity on infective stages of plant-parasitic nematodes Melodoigyne incognita. EOs from both Monarda species were strongly active on M. incognita juveniles showing a LC50 value of 1 µL mL-1 after 24 h exposure. The main constituents of EOs, carvacrol, γ-terpinene, o-cymene and thymol were also evaluated for their in vitro activity. Among them, carvacrol showed higher nematicidal activity also at low concentrations and at short exposure time [2].

Abstract
The Lamiaceae family contains important aromatic plants used in traditional and modern medicine and in food and pharmaceutical industries. Plants belonging to this family are mostly exploited for the extraction of essential oils (EOs). The genus Monarda L. includes about eighteen species of herbaceous, annual or perennial plants endemic of North America. Several biological activities have been reported for plant EOs and their main components, including a biocidal activity against plant soilborne pathogens and pests, which also includes plant-parasitic nematodes [1]. The EOs can play an important role in crop protection and have been propose as an environmentally alternative to synthetic pesticides. In this study, the EOs from two Italian species of Monarda (M. dydima and M. fistulosa) were evaluated for their in vitro activity on infective stages of plant-parasitic nematodes Melodoigyne incognita. EOs from both Monarda species were strongly active on M. incognita juveniles showing a LC50 value of 1 µL mL-1 after 24 h exposure. The main constituents of EOs, carvacrol, γ-terpinene, o-cymene and thymol were also evaluated for their in vitro activity. Among them, carvacrol showed higher nematicidal activity also at low concentrations and at short exposure time [2].I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
