Table 7 Probit analysis results of dehydroascorbate (DHA) against second-stage juveniles (J2s) of Meloidogyne graminicola. Around 400 freshly hatched J2s were exposed to different concentrations of DHA: 1, 2, 3, 4, 5, and 6 mM. The observations on nematode mortality were recorded 6, 12, 24, 48, and 72Â h after exposure
