The use of 2,4-D to intensify the skin color of pontiac potatoes

1. Experiments were conducted during the years 1950 to 1953 to determine the influences of rate, time, and method of application of 2,4-D and MCP on yields, tuber skin color, and specific gravity of Pontiac potatoes. 2. Spraying potato vines with either 2,4-D or MCP prior to tuber setting tended to reduce yields of potatoes and were less effective in intensifying tuber color than applications made when tubers were one to two inches in diameter. 3. MCP was not as effective as 2,4-D in intensifying tuber color when applied at comparable rates. 4. Rates of one-quarter to two pounds of either 2,4-D or MCP had no effect on specific gravity of Pontiac potatoes. 5. Application of one-half to one pound of 2,4-D as a basal spray to plants in full bloom (tubers 1–2 diameter) was effective in intensifying tuber skin color without reducing yields. Complete coverage sprays of 2,4-D at the same rates tended to reduce potato yields.
