Abstract
Control of bacterial canker of tomato, caused by Clavibacter michiganensis subsp. michiganensis was achieved by application of soil solarization in Greece.
Plastic house trials carried out at Preveza county between 1992–1993 showed that soil solarization (approximately 6 weeks soil mulching with transparent polyethylene sheets) in tomato plastic houses drastically reduced symptoms caused by the pathogen throughout the cropping season.
Beyond the already shown thermal effect of solarization against the survivability of the pathogen in the soil, rhizosphere isolates of Pseudomonas, Bacillus and Streptomyces species were able to survive solarization and possibly contribute to the biological control of bacterial canker of tomato in solarized soils.
Moreover, fluorescent pseudomonads isolated from the rhizosphere soil of tomato plants growing in solarized soil and applied as seed coating indicated ability to induce systemic resistance to subsequent stem inoculation of tomatoes with the pathogen.
The magnitude of the effectiveness of soil solarization against bacterial canker was so evident that convinced the tomato growers to apply the technique commercially in the region.
