Cucurbitaceae COld Peeling Extract (CCOPE) derived from melon (Cucumis melo var. cantalupensis; mCOPE) is strongly nematicidal. Second-stage juveniles (J2s) of Meloidogyne graminicola (Mg) and Meloidogyne incognita (Mi) were incubated in the buffer used for CCOPE preparation (Control), mCOPE or 0.2% (v/v) Vertimec. The latter is a commercial formulation of the nematicidal compound abamectin (Pitterna et al., 2009; Li et al., 2018) and was used as positive control. After 6 and 24 h of incubation, nematode viability was assessed. Error bars represent the standard error of the mean. Letters indicate significant differences upon investigation of all possible pairwise comparisons. Statistical differences were determined via a two-sided heteroscedastic t-test (p < 0.05).
