2. TYPES OF INTERACTION
1. Expression of different kind of disease syndrome in a
host other than the disease caused by either
pathogen alone.
2. Nematode predisposing the plants to bacterial
disease or inhibiting the development of bacterial
diseases
3. The nematode and bacterium together results in the
production of a toxin.
