Black spot or Anthracnose of grapes caused by the fungus Elsinoe ampelina is a widespread and serious disease. In commercial vineyards it is often responsible for considerable reduction in yield and quality of fruit, and in home gardens also it may prove very damaging. Under commercial conditions the disease has proved difficult to control in seasons favourable for its development despite the routine application of accepted fungicides. Fortunately, preliminary results of recent spray trials indicate that greatly improved control is likely to result in future from the use of a number of new fungicides.
