The growing point dies off ("heart rot") and also the beets get dry and die off. After rainfall, the plants may recover and form lateral leaf rosettes.

Sugar Beet: 3 l/ha at 4-6 leaf stage. For moderate to severe deficiency, repeat applications should be made at the above rate at 10-14 day intervals. Water rate: 50-200 l/ha.
