Root gall indexing (GI) of tomato plants grown in small pots for 31 and 59 days after planting (DAP) to evaluate the nematicidal effect of NEMguard^® DE against Meloidogyne incognita.

Treatment	GI 31 DAP	GI 59 DAP
pControl	5.7 ± 0.8 a	7.3 ± 0.5 a
NEMguard 1	4.8 ± 0.8 ab	6.3 ± 0.5 b
NEMguard 2	4.2 ± 0.8 b	5.5 ± 0.6 c

Root gall indexing (GI) was determined according to Zeck [25]. Values are means of n = 6, same letter in the same column indicate no significant differences using a one-way ANOVA (post-hoc Tukey HSD test). NEMguard 1 = NEMguard^® DE applied before planting; NEMguard 2 = NEMguard^® DE applied before planting followed by a repeated application 24 days after planting. Positive (p) control = control with M. incognita, negative (n) control = soil free of M. incognita.
