PP-204: Gray Leaf Spot of St. Augustinegrass: Cultural and Chemical Management Options

Figure 4. Gray leaf spot can substantially reduce vigor and can prolong the grow-in phase of St. Augustinegrass sprigged for sod production. Both sprigs in the figure were planted at the same time, but only the plot on the bottom was treated with a Qol fungicide product to prevent gray leaf spot.
