Perhaps the most severe infestation on record of the plum curculio (Conotrachelus nenuphar Hbst.) on the peach was experienced in Georgia in the season of 1920. The very heavy infestation of that year also provided innumerable punctures in the skins of the fruit, through which the brown-rot fungus, Sclerotinia fructicolo gained easy access and frequently finished the work of destruction begun by the curculio. At the urgent request of the growers, the Bureau of Entomology of the United States Department of Agriculture established a field station at Fort Valley, Ga. to undertake a study of the life history and control of the curculio. In the spring of 1921, the Georgia State Board of Entomology and the Federal Bureau of Plant Industry became cooperating agencies. The experiments were continued through four consecutive seasons at Fort Valley. The present publication is a report of the results obtained each season, together with recommendations relating to spraying and dusting for the control of the curculio, brown rot, and scab in sections of the South where these pests are particularly destructive.
