Abstract
The effect of sugar beet rust (Uromyces betae Tul. ex. rick) on crop yield and industrial qualities was quantitatively investigated . Significant differences were found between healthy and diseased plants, in root weight, sucrose % in root, non-sucrose chemical components (potassium, sodium and alpha amino adds), and quality %. Root weight, sucrose % and quality % were inversely affected by disease severity . Consequently, white sugar yield (WSY) was reduced due to the increase of non-sugar constituents which impede sugar crystallization .
