In connection with the development of Pb arsenate for control of larvae of the Japanese beetle (Popillia japonica), studies were made of the effect of Pb arsenate on the common garden vegetables. Addition of Pb arsenate to soil reduced the germination of string beans and lima beans but did not seriously impair the germination of asparagus, broccoli, carrots, cauliflower, corn, cucumbers, egg plant, okra, onions, parsnips, radishes, tomatoes, turnips, and watermelons. The arsenical might retard the seedling growth of many of the vegetables. With the exception of beets, egg plant, peppers, sweet potatoes, white potatoes, and tomatoes, a reduction in yield might be expected with garden vegetables grown on soil containing large quantities of Pb arsenate. Very little As was found in the edible portion of most of the vegetables. The largest quantities were found in lettuce, onions, radishes, and turnips.
