Studies on the crown rust of oats
Is Version Of
During some seasons crown rust of oats (Puccinia coronata Corda) becomes a serious limiting factor in successful oat production in Iowa. It is not uncommon to have this rust occur in epidemic form one year and the following year to have only a small amount of the disease present. Up to the present time the various factors which influence the growth, development and epidemiology of this rust have not been definitely studied.
