Thank you for the info., much appreciated.

"To 1 gallon of spray with Garrett Juice Plus add 8 - 16 ounces of 3 percent hydrogen peroxide (available at drug and grocery stores) and 1 tablespoon of Bio Wash. Spray the plants thoroughly."

I take it you get 1 gallon of water and add a certain amount of Garrett Juice Plus, 8-16 oz. of 3 % hydrogen peroxide, and 1 TBS of Bio Wash...

Is this correct???

Hi Jim: I only had 1 rose with RRD, that was 2 years ago. It was a multiflora-parentage rose, and was planted next to a tree. Since multiflora prefers acidic soil, I gave it too much ACIDIC fertilizer high in nitrogen. It gave too-soft and too-quick of a growth ... was susceptible to RRD mite.

None of my other 50+ roses were affected. RRD mite don't have mouth-piece, but if the tissue of rose is fast-soft-growth, then mites can gain entry. Plus that year we had a drought. Since that time, I stopped that fertilizer (with sulfur & high in chemical nitrogen and salt). No RRD in my garden last year, nor this year.

There's no RRD either at Cantigny rose park nearby (1,200 roses). They have alkaline clay, plus plenty of watering.

I got curious about Garrett Juice Plus ... here's its composition from the below site: Garrett Juice (ready to spray):

1 cup compost tea or liquid humate
1 ounce molasses
1 ounce apple cider vinegar
1 ounce liquid seaweed

For Garrett Juice Plus and more fertilizer value add:
1- 2 ounces of liquid fish (fish hydrolysate) per gallon of spray."

Here is a link that might be useful: Dirtdoctor.com on Garrett-Juice

The ingredients can be added to a gallon of water or used to replace the water for a stronger mix.
