Abstract
Peppermint and parsley are widely cultivated medicinal and aromatic plants, and like many other crops, they are vulnerable to infections caused by plant-parasitic nematodes of the genus Meloidogyne. Host status of commonly cultivated varieties and the damage potential of Meloidogyne species from temperate climates in production of these plants remain unknown. Meloidogyne species are also known to interact synergistically with other soil pathogens, contributing to disease complexes. Mint is known to be affected by soil-borne pathogens such as Verticilium dahliae, which causes severe Verticillium wilt disease. It has been reported that certain plant-parasitic nematodes, such as Pratylenchus can interact synergistically with V. dahliae on mint. However, it remains unknown whether Meloidogyne species or species from other plant-parasitic nematode groups are also capable of such interactions. In the present work, peppermint and parsley responses were investigated against Meloidogyne species from temperate climates. In addition, we assessed the potential involvement of M. hapla and Paratylenchus projectus in synergistic interactions with V. dahliae on peppermint. By examining these aspects through three separate studies, we addressed previously underexplored responses of mint and parsley varieties cultivated in Germany to Meloidogyne infection, highlighting the importance of this knowledge for developing effective and sustainable nematode management.
The impact of Meloidogyne species was determined under controlled conditions in the greenhouse. Results showed that the selected mint and parsley varieties are good hosts for Meloidogyne species. However, host status varied depending on the nematode species and plant variety. All studied varieties were susceptible to M. hapla, but showed tolerance to its infection, as no growth reduction was observed. However, at the highest density, M. hapla reduced the essential oil content in peppermint, indicating that tolerance applies only to plant growth but not to plant secondary metabolites. Furthermore, the identification of peppermint 'Multimentha' as a non-host to M. chitwoodi and M. fallax offers valuable control options by crop rotation targeting these nematodes. Additionally, M. hapla and P. projectus exhibited synergistic interactions with V. dahliae in peppermint, increasing Verticillium wilt severity. These findings highlight the critical need for integrated nematode management in peppermint cultivation affected by Verticillium wilt.
