High-resolution educational image illustrating major diseases affecting grapefruit trees and their symptoms, including citrus canker, greening disease, sooty mold, and root rot.

Educational landscape image showing common grapefruit tree diseases, including citrus canker, greening disease, sooty mold, and root rot, with visible symptoms on fruit, leaves, and roots.

The image is a high-resolution, landscape-oriented educational composite titled "Common Diseases Affecting Grapefruit Trees & Their Symptoms." It is designed as a visual diagnostic guide for growers, students, and agricultural professionals. Across the top of the image, a bold, easy-to-read title is displayed in light-colored text against a softly blurred green orchard background, immediately establishing the agricultural context. The composition is divided into four vertical panels, each dedicated to a specific disease commonly affecting grapefruit trees.

The first panel on the left focuses on Citrus Canker. It features a close-up photograph of a mature grapefruit still attached to the tree, showing multiple raised, brown, corky lesions scattered across the fruit’s yellow rind. Surrounding leaves display similar symptoms, including small, dark, crater-like spots with yellow halos. An inset circular close-up highlights the leaf damage in greater detail, emphasizing the rough texture and irregular spotting typical of citrus canker infections. The lighting is natural and even, making the lesions clearly visible.

The second panel illustrates Greening Disease (HLB). Several grapefruits hang in a cluster, showing uneven coloration with blotchy green and yellow patches rather than uniform ripening. The fruit appear misshapen and dull, suggesting poor internal quality. Leaves in the background show subtle yellowing and asymmetry. This panel conveys the systemic nature of HLB and its impact on fruit development, using a realistic orchard setting and sharp focus to highlight visual symptoms.

The third panel is dedicated to Sooty Mold. A grapefruit and surrounding leaves are partially covered in a thick, black, soot-like coating. The contrast between the dark fungal growth and the natural yellow and green of the fruit and foliage makes the symptom immediately recognizable. A circular inset magnifies the leaf surface, showing the powdery, superficial mold layer that blocks sunlight and reduces photosynthesis.

The fourth and final panel shows Root Rot. Instead of fruit and foliage, this section focuses on the base of a grapefruit tree trunk and the exposed root system. The bark near the soil line appears darkened and decayed, while the roots look damaged, brittle, and unhealthy. An inset highlights the rotting roots in close detail, emphasizing structural breakdown and moisture-related decay.

Overall, the image uses clear labeling, consistent visual style, and realistic photographic detail to compare diseases side by side. The layout supports quick identification while also allowing deeper inspection of symptoms, making it suitable for educational materials, presentations, extension guides, and online agricultural resources.
