Abstract

Bacteria (anthomonas campestris pv. vesicatoria) and root-knot nematode (Meloidogyne incognita) independently can damage and cause considerable damage to tomato (Solonum lycopersicum L.). In a disease complex, interrelationship of 2 or more pathogenic species can produce different symptoms on the same host plant. Generally simultaneous occurrence of these pathogens in a field can infect hosts plant at the same time. During development of a disease complex pathogens could influence and/or suppress each other, through synergism andor antagonism respectively. In this study the pathogens (Meloidogyne incognita and anthomonas campestris pv. vesicatoria), were used to determine how co-occurrence affects development of pathogens and disease severity, and define prerequisites for interrel
