Nematicidal activity of furanocoumarins from parsley against Meloidogyne spp.
Pest Management Science 71 (8), 1099-1105
Abstract:
BACKGROUND
This report describes activity against Meloidogyne spp. and chemical characterisation of the essential oil and methanol extract of Petroselinum crispum aerial parts. The study was based on the hypothesis that P. crispum could be used as an intercrop and soil amendment in tomato culture for nematode control.
RESULTS
The methanol extract and the essential oil exhibited significant nematicidal activity against M. incognita, M. hapla and M. arenaria, the first being the most sensitive species, with EC_{50/72 h} values of 140 ± 15 and 795 ± 125 mg L^-1 for the extract and oil respectively. The most abundant furanocoumarin compounds in the methanolic extract were xanthotoxin, psoralen, bergapten and oxypeucedanin; levels ranged from 1.77 to 46.04 mg kg^-1 wet weight. The EC_{50/24 h} values of xanthotoxol, psoralen and xanthotoxin against M. incognita were 68 ± 33, 147 ± 88 and 200 ± 21 mg L^-1 respectively. The addition of fresh parsley paste to soil reduced the number of M. incognita females and plant galls on tomato roots; EC₅₀ values were 24.79 and 28.07 mg g^-1 respectively. Moreover, parsley paste enhanced tomato growth in a dose–response manner.
CONCLUSIONS
Parsley exhibits promising nematicidal activity as an organic amendment and as a source of nematotoxic furanocoumarins.
