Paperback. Condizione: New. Print on Demand. This book presents a comprehensive series of experiments comparing the efficacy of dusting and spraying in the management of apple and peach pests. Conducted in 1921, the experiments utilized a range of treatments including sulfur-lead dust, Sanders dust, liquid lime-sulfur, and dry lime sulfur. Across apple orchards, the author found that spraying tended to be more effective than dusting, particularly for controlling apple scab, while both methods outperformed untreated controls. In peach orchards, dusting with sulfur or sulfur-lead arsenate dust produced a slightly higher proportion of quality fruit than spraying with atomic sulfur, effectively managing both scab and brown rot. The experiments provide detailed insights into the relative value of dusting and spraying in controlling pests and diseases in fruit orchards, offering practical guidance to farmers and orchardists seeking to protect their crops.
