The American Chemical Society has developed a wearable plant detector that helps farmers and gardeners detect plant stress early. The sensor, which attaches to leaves, monitors hydrogen peroxide, a chemical plant response to stress. This device simplifies current methods and provides quick, inexpensive results. It can be used multiple times before needing replacement. Researchers tested it on soybeans and tobacco plants, showing that it could significantly improve crop monitoring and yield by allowing earlier detection of stress and disease.
