“…campestris on cabbage and the influence of the method applied was demonstrated as biological control measures. The incidence and severity of Xanthomonas black rot in the foliage, stems and heads of the highly susceptible cultivar, Copenhagen Market, were significantly reduced, especially when antagonists were applied through the roots as compared to application through the seeds or foliage (Massomo et al, 2004).…”

Xanthomonas campestris pv campestris (Xcc), causing black rot, is one of the most yield-limiting and destructive pathogens of cruciferous crops. The intention of this study was to evaluate the potential of rhizobacteria in black rot management. Fifty-four isolates from rhizosphere soil of Brassica campestris were screened against Xcc. Two isolates namely, KA19 and SE, with inhibition radius >11 mm were selected. The combined use of them produced an average inhibition zone of 18.1 ± 1.4 mm radius (P < 0.05). 16S rRNA gene sequencing and phylogenetic analysis identified KA19 and SE as the nearest homologs (>99.4%) of Pseudomonas aeruginosa and Bacillus thuringiensis, respectively. In greenhouse study, both isolates were effective (P < 0.05) in reducing black rot lesions compared to untreated control involving either a foliar spray or the combined seed soak and soil drench. However, the combined strains (KA19 + SE) were significantly more effective (P < 0.05) when the mode of application was combined seed and soil drench. The lipid content of seeds increased significantly with the application of these strains, especially with SE alone and in combination. After 9 weeks, the Xcc population was significantly lower in soil treated with combined strains (P < 0.05). KA19 produced extracellular siderophores, influenced by various carbon sources and identified as 4-hydroxy-2-nonyl-quinoline by NMR. In Bacillus SE, two antibacterial factors corresponding to autolysins (β-N-acetylglucosaminidase) and AHL-lactonases were established. This study would strengthen our understanding for application of different rhizobacteria with various active principles like Pseudomonas and Bacillus as ingredients of a biocontrol mixture.

“…In close collaboration with respective seed companies, agricultural research systems should continue with introduction and screening of cabbage cultivars for black rot resistance as well as demonstration and dissemination of promising cultivars using farmer participatory research approach. In addition, agricultural researchers should continue to work on the development of alternative strategies, such as biocontrol (Massomo et al, 2004b), for the integrated management of black rot. The research and extension systems should also jointly address the need for training farmers in cabbage production, with emphasis on black rot management strategies and proper usage of pesticides.…”

Black rot caused by Xanthomonas campestris pv. campestris, has increasingly become the major constraint to sustained production of cabbage in Tanzania. On-farm surveys were carried out in northern Tanzania to gain an insight on cabbage production practices in relation to the prevalence of black rot. The studies revealed a rapid increase in cabbage Said M. S.
