Paperback. Condición: New. Print on Demand. This book presents the results of spraying experiments conducted between 1908 and 1912 by the Maine Agricultural Experiment Station. In these apple orchard experiments, the authors tested out lime sulfur as a substitute for the standard bordeaux mixture of the time. Their comparative results on scab control and foliage injury using lime sulfur and bordeaux mixture are meticulously documented. The results from these experiments had a significant impact on the apple industry; they helped establish for orchardists that lime sulfur was a more effective and safer spray than the standard bordeaux mixture. Their work provided critical data for the widespread adoption of lime sulfur as a summer spray for apple orchards in the present day.
