| | IPM : Landscape and Turf : Leaf Scorch of Woody Plants |
 | | Scorch is most common follow-ing prolonged periods of dry, windy weather or bright sunshine when the roots are unable to supply water to the foliage as rapidly as it is lost through the leaves by transpiration. |
 | | Scorch usually develops on broad-leaved plants as an irregular yellowing, browning, or bronzing of tissues between the veins or along the margins and tips of leaves (Figures 1 and 2). |
 | | Scorch due to exposure from such things as excessive fertilizer, deicing salt, herbicide, dog urine, trash fires, leaking sewer or gas mains, girdling roots or strangling wires, vehicle exhaust, and heat reflected from buildings or pavement can be prevented only by removing or avoiding the specific cause or causes. |
