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<sup>−1</sup> wet weight. The EC<sub>50</sub><sub>/24 h</sub> values of xanthotoxol, psoralen and xanthotoxin against <italic>M. incognita</italic> were 68 ± 33, 147 ± 88 and 200 ± 21 mg L<sup>−1</sup> respectively. The addition of fresh parsley paste to soil reduced the number of <italic>M. incognita</italic> females and plant galls on tomato roots; EC<sub>50</sub> values were 24.79 and 28.07 mg g<sup>−1</sup> respectively. Moreover, parsley paste enhanced tomato growth in a dose–response manner.</p> </sec> <sec id="ps3890-sec-0003" sec-type="section"> <title>CONCLUSIONS</title> <p id="ps3890-para-0003">Parsley exhibits promising nematicidal activity as an organic amendment and as a source of nematotoxic furanocoumarins. © 2014 Society of Chemical Industry</p> </sec> </abstract>
