RUST & MILDEW~~WHICH PRODUCT??

Hi everyone!
I have a problem with Rust on my Hydrangea & HollyHocks & Mildew on other things like Bee Balm & Zukes. I did plant a Mildew-resistant Bee Balm, but don't want to remove the other one if I can treat it. I see that there are two natural products in the catalog: 70% Neem Oil & Physan 20 that are suppose to take care of this problem. Has anyone had any experience with either of these? And which would you recommend. Thanks!

The Physan will take care of the rust as well as other fungal and bacteria problems. It's a great product and completely biodegrades in 48 hours so there is no residual to worry about. Use at two teaspoons/gallon of water and thoroughly wet the plant. This is a curative formula and not preventative. However it's so safe and effective that I spray my plants with it about every two weeks during growing season just to keep ahead of problems. It is also good for the algea that gets on the house, landscape rocks & timbers.

The Neem Oil is a very good organic pesticide and is the most effective one I've used for Mealy Bugs, I hate those things.
