User reviews

Useful for Ag professionals

This app is helpful for quickly quantifying the severity of disease lesions on plant tissue for use in determining treatment thresholds.

Confusing

I genuinely have no idea how to use this app.

Doesn’t work

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.

Read the description folks

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.

My Aloe plant

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.
