Looking for Pre-Trained AI Models for Crop Disease Detection While I Train My Own

I’m currently experimenting with image-based plant disease detection and I’m in search of general-purpose, pre-trained AI models for crop disease classification.
If you’ve worked with or know of:
Pre-trained models (TensorFlow, PyTorch, ONNX, etc.)
Able to detect multiple types of crop diseases (not just limited to one crop)
Open source or easy to integrate into a small-scale image classification tool
Compatible with basic web interfaces or APIs
I’d really appreciate any pointers or links you can share!
This is part of a broader personal project I’m working on related to agriculture and AI ..more details coming soon .
Thanks in advance for your support!
Feel free to DM me if you’ve worked on something similar and open to chatting.
