10 Best Free Plant Disease Identification Apps

Last Updated on 8 months by Namrata

I enjoy gardening at home and find great joy in watching my plants grow beautifully. However, it saddens me to see a plant that is struggling or dying. As an amateur gardener, identifying plant diseases can be challenging. It would be helpful to have a mobile app that provides easy-to-follow instructions for detecting plant diseases quickly, instead of having to sift through a book with an overwhelming number of options. Such an app would be incredibly useful.

Artificial intelligence (AI) has become useful in many sectors like medicine and agriculture. AI has become so advanced that it can detect diseases just from a picture of the infected plant. This new era of AI has revolutionized plant disease identification apps.

AI operates using data, and as it is provided with more data, its capabilities become stronger. Over time, AI will continually improve and excel in its tasks.

You have the option to download several apps from both the Google Play Store and Apple App Store onto your mobile device in order to detect and diagnose any plant diseases that may occur in your home.
