Figure 1:

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).
