What's best?

Read label for dilution instructions and spray now.

Forget the Neem b'c its mode of action, which is pretty lousy as an anti-fungal, from what I've been reading over the past several years from feedback, is completely different from Daconil.

I got what they had and that was a spray bottle "ready to use" except it's as thick as buttermilk hence doesn't spray well.

That's an issue in itself.

Now it's supposed to rain. So if I sprayed the plants, and I did, and it rains 4 hours later, am I still in good shape or do I need to respray?
