Studies of some market diseases of tomatoes with special reference to anthrachose (colletotrichum phomoides (sacc.) chester).

Anthracnose of tomatoes is a fungus disease that manifests itself on ripe fruits. A survey of fruit diseases on the Montreal market showed it to be one of the most important of the tomato diseases. Since it is essentially a rot of ripe fruits, the principal losses occur in the retail stores. Losses caused by anthracnose have also been sustained, however, by field growers picking ripe tomatoes for the local market and for canning (McNew,1943a), A survey of the literature showed that, even though the disease was recorded as early as 1881, comparatively little was known about the life history of the causal organism, the factors affecting the development of the disease, or the control measures that might be employed. This investigation was therefore undertaken in an attempt to gain some information on these points
