aAbbreviations: DMDS = dimethyl disulfide; MNa = metam sodium; MB = methyl bromide.
bCucumber height collected at 4 WAT.
cRoot galling index and root disease index were collected at the end of the trials.
dIn each column, data are means of three repeats. Means followed by the same letter are not different (P = 0.05) according to the LSD test.
