ROOT ROT AND OTHER DISEASES OF SUGAR BEETS

In 1964 the most widespread and deleterious diseases of sugar beets were root rot in the shoots, cercospora infection, powdery mildew, peronospora infection, mosaic, viral jaundice, starvation diseases, fusarium and storage rot. Less often zonal and bacterial spots on the leaves, rust, dodder, and brown root rot are encountered and they inflict damage only in areas where they are manifested the most. Very rare are leaf spot caused by Ramulispora, cancer, tuberculosis and mange scab of the roots which have caused negligible losses of sugar beet harvest.
