Plant patnoiogists at virguua Tech said the disease showed up early in Southeastern Virginia where it is reaching a critical stage. Other areas of the state also are expected to suffer severe losses.
“The hot, humid weather in the early part of the growing season enabled the blight to get a good start,” explained Curtis W. Roane, professor of plant pathology. “We expect it to be a great deal worse than last year.”
Growers have been expressing an interest in controlling the disease with fungicides.
“Although we do not have data from Virginia on the effectiveness of spraying for southern corn leaf blight, data from Florida last year indicates that it is economically feasible under certain conditions,” noted Robert Pristou, associate professor of plant pathology. The extension specialist said “Many think that it is not feasible to control blight by applying a fungicide. This is probably true for the grower who plants only a few acres and normally makes a low yield. But it is not true for the large grower who consistently makes a yield of 90 or more bushels per acre.”
