Abstract: The fungicide captan was applied to almond trees for the control of Coryneum blight (Coryneum beijerinckii Oud.) and Hendersonia leaf blight (Hendersonia rubi Sacc). Applications were made by ground air-carrier sprayers (low- and high-volume gallonages), by helicopter, and by fixed-wing aircraft. The extent of disease control was determined for each method of application and compared to captan deposits on leaves and on glass microscope slides placed in the trees at various levels.
