The introduction of dangerous potato diseases, (notably powdery scab and black wart); the Federal grade regulations, and the demands of many states that potatoes for propagating purposes be certified, as to purity and freedom from diseases, has aroused unusual interest in the standardization of potato shipments from the various northern potato growing centers. Early in 1919, the potato growers of the state felt an urgent need for definite lines of potato improvement. Accordingly, a plan for inspection and certification of potato seed stock was inaugurated. This move was entirely voluntary on the part of the· potato growers and was placed under the direction of the Extension Division of the State College.
