Abstract

THE result of fungicidal spray experiments conducted in 1952 showed that although Phygon XL gave promising control of early blight or black spot of tomatoes, it was ineffective against the same disease on potatoes. A new Zineb type of fungicide in the proprietary form, Dithane-Z78, which gave outstanding control of early blight on potatoes in 1952, was tested against Phygon XL in a further trial on tomatoes at Geraldton. Dithane-Z78 proved equal to Phygon XL in controlling the black spot disease, both materials being superior to the standard copper oxychloride spray.
