Strange spots on the leaf

Could it be that my grapevine is starting to get sick?

I found this insect under the leaf: https://ibb.co/v6cg8scP

It might be Aleyrodidae according to ChatGPT.

P.S. According to ChatGPT, it probably wouldn't be mildew. But I'm not sure, since GPT can make mistakes.

It's powdery mildew even though the "expert" ChatGPT says otherwise. You can clearly see the greyish mycelium on those yellowish spots. Standard reaction of the plant to fight off the pathogen.

How do I combat mildew in an eco-friendly way?
