I should add that I wasn't intending to advocate the use of detergent products, just commenting that it's not impossible for them to have an affect on rust, as the study illustrated. As they said in the study for Ultra Dawn: "Although the two treatments (17 & 31 July 2002) were not observed to cause phytoxicity on these plants, we do not know the effects of longer term (e.g. season long) multiple applications of diluted dishwashing liquid on daylily plants."

Can you be a little more specific - that is about the product and where to find it.
I googled green magic cleaner and all I found it an automotive product.

Thanks

Green Magic is available on Ebay and Lily Auction ($20 free shipping)

It is suggested to use 4 oz per gallon for the 1st couple of sprays and then drop to 2 oz per gallon.
I use whichever strength I feel necessary at the time; i.e., if it is humid and rust is very active, I use the 4 oz mixture.

The plant inspector said my plants looked better than those at the 'big' farms.

Who inspects your plants? My SIL works for the state and does Nicole Harry's. She works Marion county.
