Moussa Lobna* and Hanaa Zawam( 2010). Efficacy Of Some Biocontrol Agents On Reproduction And Development Of Meloidogyne Incognita Infecting TomatoJournal of American Science 2010;6(11) 495-509]. (ISSN: 1545-1003).
Abstract: Three rhizobacteria and two yeasts isolates were used as biocontrol agents against Meloidogyne incognita in laboratory and greenhouse. The used biocontrol agents were identified as Bacillus amyloliquefaciens, Brevibacterium otitidis, Sanguibacter inulinus, Candida incommunis and Wicherhamiella domercqiae. They inhibited the egg-masses hatching in vitro and exhibited strong nematicidal activity by killing the second stage juveniles of Meloidogyne incognita to various degrees in greenhouse. The most effective treatment was the complete culture of the four biocontrol agents (propagules and filterate) suppressed galls and egg-masses formation by 100% Br. otitidis reduced galls and egg-masses by 43.7 and 52.19 %, respectivily compared with the untreated control. The microorganisms used in greenhouse test reduced nematode populations in the rhizosphere and promoted the growth of tomato plants over the control treatment.
