Insights into the epidemiology of chlorotic streak disease as determined by multiple field assessments* [Full subscriber]

Abstract During annual ratoon stunting disease (rsd) seedbed inspections at Harwood, assessments of the relative prevalence of chlorotic streak disease (CSD) were recorded on a scale of 0 (none evident) to 3 (highly prevalent). Over a three-year period (2012–2014), these assessments were made for 32 varieties growing in 1106 seedbeds. Additionally, the degree of crop uniformity was recorded (0 = even, 3 = highly uneven), as uneven distribution of CSD in a field can lead to a patchy presentation of the crop. There was variation in the level of CSD and crop unevenness among varieties, while there was significantly less…
