Image: Common Pests and Diseases of Pistachio Trees

This landscape-oriented, high-resolution educational infographic presents a clear visual overview of common pests and diseases affecting pistachio trees. The scene is set in a sunlit pistachio orchard with evenly spaced trees receding into the background, providing agricultural context and a sense of scale. At the center of the composition is a sharply focused pistachio branch bearing clusters of ripening nuts in various stages of maturity, from green to pinkish hues, with several shells showing visible discoloration, lesions, or decay. Surrounding this central branch are eight rectangular inset panels, each connected by thin white leader lines that point to the relevant area of the branch, visually linking symptoms to their causes. Each inset contains a close-up photographic depiction of a specific pest or disease, accompanied by a bold label on a dark green banner for easy identification. On the left side, the upper inset shows a pistachio psyllid, a small insect resting on a leaf surface, illustrating its size and appearance. Below it, an aphid infestation is depicted with clusters of small green aphids densely covering a leaf, emphasizing the severity of colonization. A third left-side inset illustrates Verticillium wilt, showing wilted, drooping leaves and branch dieback, conveying systemic plant stress. Along the bottom center-left, panicle blight is shown with darkened, shriveled flower clusters, highlighting damage to reproductive structures. On the bottom center-right, Alternaria late blight is illustrated by pistachio nuts with dark fungal spots and surface mold, emphasizing post-infection discoloration. On the right side, the upper inset shows a navel orangeworm larva inside a nut, clearly visible against the shell interior, demonstrating internal feeding damage. Beneath it, stink bug damage is depicted by an insect perched on a pistachio nut, suggesting puncture and feeding injury. The lower right inset presents Botryosphaeria blight, with cankered, blackened branches and cracked bark, indicating severe woody tissue infection. At the bottom of the image, a wide green banner spans the frame with the title text "Pests & Diseases Affecting Pistachio Trees" in large, high-contrast lettering. The overall color palette is natural and agricultural, dominated by greens, browns, and earthy tones, while the clean layout and sharp photography make the image suitable for extension publications, agricultural training, presentations, and educational materials focused on pistachio crop health and integrated pest management.
