Pollach, G.: Tests on improvement of Rhizomania diagnosis based on conventional beet analyses (German).
Zuckerindustrie 109 (1984) pp. 849-853.   List of papers
Abstract: The beet disease, Rhizomania, causes changes in the concentrations of some beet constituents, which can be determined routinely using automatic analysers. An attempt was made to calculate a Rhizomania-indicating characteristic from a number of these quantifiable symptoms. It is shown in graph form for Austrian beet material from the years 1978-1983.
