Epidemiology of Leaf Scald in the Moreton District of Queensland
نویسنده
چکیده
The incidence and geographic distribution of leaf scald (Xanthomonas albilineans (Ashby) Dowson) in the Moreton district between 1951 and 1975 is described. Most of the infection has been in 471. Increase in incidence of the disease appears to be favoured by periods of high rainfall followed by dry weather. A survey was made, at monthly intervals from January to June 1975, to try to determine long-term sources of infection. Leaf scald was again found as a natural infection in blady grass (Imperata cylindrica var Major (Nees) C. E. Hubbard) on a farm in the Yandina area where it had previously been found in 1971. Recommendations are made for controlling the disease.
