<p>Rhizobacteria having nemastatic properties introduced to the rhizosphere of a plant host are to protect said plant host against nematode and fungal infestation. Particularly, Serratia marcescens strain NA1 provides significant protection to susceptible plant hosts and can be used as a source for genetic material for introduction to other bacteria to provide the desired properties. Colonization of the rhizosphere and production of anti-nematodal toxins by the rhizobacterial strain may be enhanced by the application of a suitable nutrient source, particularly one having assimilable nitrogen.</p> |
