The late blight is much more serious. The vines may be so badly injured that no tubers will be formed. Spraying with Bordeaux mixture is the remedy. Scab and rot are diseases that attack the tubers underground. Fig. 88. The flower and leaf of the sweetpotato plant. They also may be very destructive. Uses.--Potatoes are used most largely for human food. They are also valuable for stock food, either raw or cooked. From the tubers, starch and alcohol are made. Sweet-potatoes.--The sweet-potato, which is a staple food crop in the South, differs from the Irish or white potato in that it is a true root and not an enlarged underground stem or tuber. It has no eyes, no leaf-buds. Small rootlets run out from it. It belongs to the same family of plants as the morning-glory, and the flowers resemble those of the morning-glory. The sweet-potato probably came originally from tropical America. It is now in cultivation in many of the islands of the Pacific. For the new crop all or part of the sweet-potato itself may be planted. Usually, however, the sweet-potatoes are started in a hotbed and the young plants are removed and set in the field when they are of the right size. Some persons make a business of growing the small plants to sell to farmers for planting their crops. The sweet-potato does best in a warm, sandy soil that is well drained and that contains humus. The land is plowed four to six inches deep. The seed-bed is made fine so as to be a good home for the transplanted plants. The plants may be transplanted by hand or with a machine. They are usually set eighteen inches apart in the row. Three or four cultivations, more
