Response of Meloidogyne javanica to root exudate concentration. (a) Chemotaxis index (CI) for dilutions of tomato root exudate (TRE). (b) CI for concentrated and diluted TRE. (c) CI for dilutions of Medicago root exudate (MRE). A 10 μl microassay was used to obtain the chemotaxis index after 6 h. Each bar represents the average of 3 replicate assays with SD shown.
