a slope standard error.

b P-value.

Inhibitory hatching rate of *Meloidogyne enterolobii* after 24h, 48h, and 72h of exposure to varying concentrations (A) cyclobutrifluram, (B) fluopyram, (C) hymexazol, and (D) fluensulfone in a 24-well microplate egg hatch assay. Bar values represent means ± standard error of three replicates. Treatments within the same experiment, connected by the same letter, were not significantly different according to the Protected LSD (α = 0.05).

Treatment	Disease Incidence (%)	DI^a (0–100)	GI^b	EMI^c
Cyclobutrifluram	78 ± 5.3^d ab	13 ± 0.8d	69 ± 5.0d	51 ± 1.5c
Fluopyram	50 ± 19.5b	7 ± 2.7d	64 ± 2.2d	36 ± 9.6c
Fluensulfone	83 ± 0.0ab	25 ± 1.6c	157 ± 10.0c	150 ± 11.0b
Hymexazol	100 ± 0.0a	38 ± 2.4b	238 ± 21.1b	238 ± 20.7a
Control	100 ± 0.0a	46 ± 4.2a	313 ± 19.6a	256 ± 26.4a

a–c DI, disease index; GI, gall index; EMI, egg masses index.

d Values are means ± standard error. Any means within the same column not connected by the same letter are considered significantly different according to Protected LSD (α = 0.05).
