eDamuhan is an Android app developed by PhilRice, designed to help rice farmers and extension workers in the Philippines identify and manage weed species in their rice fields. The app uses cutting-edge artificial intelligence technology to recognize images of different weed species in the rice field. It also has a catalog of weed species, including their scientific and local names, their impact on rice, and recommended management practices.

One of the best features of eDamuhan is that it works offline, so farmers and extension workers can access information and recognize weeds without an internet connection. The app is free to download and use, making it an accessible and valuable tool for managing rice weed species. However, it's worth noting that the weed recognition feature is currently a test functionality and can only recognize 22 weed species, but it will be improved in future versions.
