Abstract

In a preliminary experiment conducted at St. Alban's Vineyard, Upper Swan, during the 1952-53 season, excellent control of the serious black spot or anthracnose disease of grapes was obtained with some new spray materials. The results which were reported in this Journal (1) indicated that Ziram, Thiram and Captan fungicides were superior to standard copper sprays and their effectiveness for disease control was approximately in that order. As these spray materials were tested only in large scale unreplicated plots, the experiment was repeated again at Upper Swan last season and a smaller replicated trial was also conducted at Caversham to provide fuller information. The results have confirmed the findings of the first year's experiment in all essential details.
