A survey was made of the fluoride content of foliage and fruit of two important wine grape varieties grown in western Riverside and San Bernardino counties, California. Abnormally high fluoride concentrations were found in mature grape leaves collected as far as 9 miles downwind from a steel mill, the major source of this element in the local atmosphere. Periodic samplings of leaves from two of the more important commercial varieties, Zinfandel and Palomino, indicated a gradual accumulation of fluoride by both varieties during the growing season. Where comparison was possible, Zinfandel accumulated slightly more fluoride but exhibited somewhat fewer symptoms of injury than did Palomino. In general, incidence of leaf injury, a characteristic marginal necrosis, correlated well with fluoride content, but indications are that other factors, such as temperature, humidity, and available soil moisture also influence the extent of injury. Although the leaves contained over 100 ppM F on a fresh-weight basis, fruit harvested within 2 miles of a large steel mill contained only about 1.3 ppM fluoride. The effects, if any, of elevated fluoride concentrations and subsequent marginal necrosis on grape production cannot be determined from the information now available.
