The Leaf Doctor performs quantitative assessments for plant diseases on plant organs such as leaves. Users collect or submit photographs of diseased plant organs and calculate the percentage of diseased tissue. Through a user’s touching of the device screen, the algorithm employs user-specified values for up to eight colors of healthy tissues in the photograph. The color of each pixel is then evaluated for its distance from the healthy colors and assigned a status of either healthy or diseased. Users may slide a threshold bar until satisfied that diseased tissues are represented accurately before the percentage calculation. The assessment data and photographs may be sent by e-mail to any recipients. Instructions for using the app are provided on the About screen. The Leaf Doctor was produced by the University of Hawaii at Manoa, College of Tropical Agriculture and Human Resources.

Why are the instructions in grey? They are small font and hard to read. At least, if they were in black I could read them.

If you want a diagnosis and assistance with control, see your local county extension agent. If you need to quantify the % leaf area containing lesions using an iPad then use this. Glad this is available. I am going to try it out and see if it can assist technicians with conducting ratings.

There is something wrong with my Aloe and I figured that this app could tell me what was wrong with it and how to fix it. Instead, it told me that my plant was healthy when it obviously is not.

The app tells me everything is healthy. No matter the threshold, no matter the plant. Some of the plants I KNOW are sick. App doesn’t work.
