Abstract
The activity of Cinnamomum cassia essential oil (EO) and (E)-cinnamaldehyde was investigated on the phytoparasitic species Meloidogyne incognita, Globodera rostochiensis, and Xiphinema index. Juveniles (J2) or eggs of M. incognita and G. rostochiensis and mixed-age specimens of X. index were exposed to 12.5–100 µg mL−1 concentrations of the two products. The suppressiveness of soil treatments with 100–800 mg kg−1 soil rates of the C. cassia EO and (E)-cinnamaldehyde to M. incognita and G. rostochiensis was assessed on potted tomato and potato, respectively. A 24-h exposure to a 12.5 µg mL−1 solution of (E)-cinnamaldehyde resulted in more than 68% mortality of M. incognita J2, while a poor mortality occurred at the same concentration of the whole EO. The mortality of G. rostochiensis J2 ranged 39 and 42%, respectively, since after a 4-h exposure to a 12.5 µg mL−1 solution of both products. All the X. index specimens died after a 48- and 8-h exposure to a 100 µg mL−1 solution of the EO and (E)-cinnamaldehyde, respectively. Egg hatch was reduced by more than 90% after exposing the M incognita egg masses or the G. rostochiensis cysts to 800 µg mL−1 concentration of both EO and (E)-cinnamaldehyde for 24 and 96 h, respectively. The infestation of M. incognita and G. rostochiensis on tomato and potato, respectively, was significantly reduced by all soil treatments with both products, though (E)-cinnamaldehyde generally resulted more suppressive than the whole EO to both nematode species. According to these results, C. cassia EO and (E)-cinnamaldehyde could be suggested as a potential source of new environment-friendly nematicides.
期刊介绍:
Journal of Pest Science publishes high-quality papers on all aspects of pest science in agriculture, horticulture (including viticulture), forestry, urban pests, and stored products research, including health and safety issues.
Journal of Pest Science reports on advances in control of pests and animal vectors of diseases, the biology, ethology and ecology of pests and their antagonists, and the use of other beneficial organisms in pest control. The journal covers all noxious or damaging groups of animals, including arthropods, nematodes, molluscs, and vertebrates.
Journal of Pest Science devotes special attention to emerging and innovative pest control strategies, including the side effects of such approaches on non-target organisms, for example natural enemies and pollinators, and the implementation of these strategies in integrated pest management.
Journal of Pest Science also publishes papers on the management of agro- and forest ecosystems where this is relevant to pest control. Papers on important methodological developments relevant for pest control will be considered as well.
