Data are averages and standard deviations of three replications.

^aAbout 80 second-stage juveniles of M. incognita were immersed in the same volume of organic acid dilutions and examined one day after treatment.

^bMixture concentration is the sum of concentrations for the same volumes of each organic acid (ex. 0.5% MX = 0.25% AA + 0.25% LA).

^cMeans with the same letters in a column denote no significant difference at P ≤ 0.05 by Duncan’s multiple range test.

^dMeans with the same letters in a row denote no significant difference at P ≤ 0.05 by Duncan’s multiple range test.
