AI camera tool spots and grades peach leaf disease outdoors
Crop Improvement
If you grow peach trees, catching shot hole disease early and knowing how bad it is could save your harvest before the damage spreads to healthy leaves.
Peach trees often get a disease called shot hole, which leaves tiny holes and spots on leaves and can hurt fruit quality. Scientists trained a computer vision model to recognize this disease straight from photos taken in real orchards, cluttered backgrounds, overlapping leaves and all, and then sort the severity into healthy, mild, moderate, or severe. The tool is small and fast enough to run quickly, giving growers a practical way to check tree health without needing an expert to inspect every leaf by hand.
Key Findings
The YOLO-PSH model achieved 81.49% average detection accuracy on a custom dataset of 800 peach leaf images with 9,183 annotated disease spots.
Severity grading accuracy varied by category: 81.82% for healthy, 60.00% for mild, 72.22% for moderate, and 91.67% for severe cases.
The model is lightweight (1.82 million parameters, 7.00 MB size) and fast, processing each image in about 7.1 milliseconds.

Researchers built an AI vision model that spots shot hole disease on peach leaves in real orchard photos, even when leaves overlap or the background is messy, and it can also rate how severe the infection is.

The peach is a deciduous tree that bears edible juicy fruits with various characteristics. Most are simply called peaches, while the glossy-skinned, non-fuzzy varieties are called nectarines. Though from the same species, they are regarded commercially as different fruits.
