Scope and Contents

From the Series:

There are 9 boxes of photographs arranged by size: 8 x 10 (1 box), 5 x 7 (6), and 4 x 5 (2). The collection includes photos by Pirone and associates as well as stock photos of chemical products and tree maintenance companies, including Monsanto Corporation and U.S. Rubber Company, for which Dr. Pirone respectively tested “Krillium” and “Rapidgro” products. The photographic record documents controlled experiments, development of methods (air-layering) and devices (aeropropagator) for preventive maintenance and tree care, demonstrations of procedures and equipment, laboratory cultures, insects, bacterial and fungal pathogens, and diseased or damaged plant subjects in situ. One sequence was used as figures for Maintenance of Shade and Ornamental Trees. There are also several portraits of Dr. Pirone (and associates) at work in the field and his laboratory. All photos with corresponding negatives are cross-referenced.
