Abstract
Three Pseudomonas fluorescens strains and the type strain Pseudomonas putida CFBP2066 inhibited invasion of the plant‐parasitic nematodes Radopholus similis and Meloidogyne spp. in banana, maize and tomato roots. Results were, however, not always significantly different from controls. One Ps. fluorescens strain kept R. similis numbers significantly lower in banana roots after the initial invasion stage. All strains also showed an in vitro repellent effect towards the nematodes, with Meloidogyne spp. being more affected than R. similis. As Ps. putida CFBP2066 was negative for the enzymatic activities tested as well as HCN productivity, it was concluded that either other chemical bacterial compounds affected nematode infectivity or strains elicited induced systemic resistance in plants.
