The Relationship

The incidence of common blight, halo blight and brown spot on French beans was surveyed in the Bairnsdale-Lindenow and Orbost areas in East Gippsland during the 1975-76 and 1976-77 growing seasons. Common blight and halo blight were severe only during late January to March, and occurred largely on mature crops. Common blight was the more severe disease in the Orbost area whereas halo blight was more severe in the Bairnsdale-Lindenow area. Brown spot occurred throughout the season on crops of all ages in both areas but was more severe in the Bairnsdale-Lindenow area. The relationship of weather to the incidence of bacterial blights in the two areas is discussed. It is inferred that losses due to common blight and halo blight could be considerably minimized by timing the planting of crops to harvest them by mid-February.

Pseudomonas Phaseolicola

Survival of Pseudomonas phaseolicola and Xanthomonas phaseoli in soil between successive bean crops was studied in a field situation at Bairnsdale. P. phaseolicola and X. phaseoli survived on nylon netting for maximum periods of 6 and 3 weeks, respectively, on the soil surface, and for 6 and 2 weeks when buried. On infected leaf, stem and pod tissue P. phaseolicola survived for 20 weeks on the soil surface and for 11 weeks when buried; X. phaseoli survived up to 11 weeks on the soil surface and for 3 weeks when buried. In heavily infected bean plots neither pathogen was carried over from one growing season to the next. It is concluded that infected bean debris in the soil from the previous growing season is not a source of common and halo blight infection in East Gippsland.
