They used a 1.8% solution. This would be 2.5 oz or 5 TB of soap to a gallon of water. They applied the soap every 10 to 14 days. I'd suggest trying Antibacterial Ajax since I'm not such which particular Equate product they used.

I wonder, however, if soap of any kind wouldn't be detrimental to insects, both beneficial and non-beneficial?

I do admire you, michaelg, for being able to stand up and admit you make a mistake.

IT WILL BURN YOUR LEAVES!!! especially at this time of the year with this heat and hot sun

i tried this with three of my rose bushes and almost all of my leaves were burnt! after 2 days in the sun! i washed it off with water the best

I use Sulphur dust now mixed with water

Kim, we are not discussing random chemical testing. We are discussing using treatments that have been tested by Ph.D. scientists at Universities, and published in reviewed scientific journals.

Mike Rivers, yes, there are concerns about the safety of triclosan. The EPA is reviewing its 2008 reregistration eligibility decision.
http://www.epa.gov/oppsrrd1/REDs/factsheets/triclosan_fs.htm

Concerning your statement: " I think the chances that triclosan will ever be certified for organic use are zero."

By definition I would expect that it would not be eligible for organic use certification even if it was completely safe. Am I misunderstanding what "organic use certification" means?
The organic forum states the following: "This forum is meant for the discussion of organic gardening. Organic gardening is most easily defined as a philosophy that stresses the use of naturally occurring substances and friendly predators and avoiding man-made chemical fertilizers and pesticides. This is the philosophy which guides this forum."

H,Kuska comment: Triclosan, I assume, is man-made.

i used 1 tablespoon of antibacterial soap mixed with 1 liter of water it did more damage then the blackspot

Personally, I do not spray anything. I do recognize that there is a real need to find safer substitutes for some/many of U.S. "approved" rose fungicides. As a scientist, I can provide information about what has been published in reviewed scientific journals. In this case the paper that Michael mentioned that I had cited was selected by me for another thread ("Organic fungicide that works") because it reported a recent study of a bicarbonate.

For this thread, as Mike Rivers correctly pointed out" If you Google triclosan, you'll find it as big a concern for human safety as the usual rose fungicides."

I've gotten a lot of great advice on this forum and through the collective sharing of its members, found methods that work and those that don't. I believe that most of the information came from people whose real names, credentials, and education backgrounds are concealed behind the anonymity of their forum names and I am CERTAIN that 99% of them haven't been doing tests in laboratory environments or subjecting their findings to a scientific peer review board.

I have also read complete silliness here. The point is that I could claim that drenching my roses in maple syrup makes them not only delicious, but has successfully prevented chili thrips in Illinois.

You can post whatever you want on the internet & if you scream "LOOK AT ME" loud enough, some people [as Kim said] will take your word as gospel. On the other end of the spectrum we have scientists who require hard facts and evidence. I believe the majority of people are somewhere in the middle of those 2 extremes.

In the last year I've seen a number of common household items touted as THE best cure for Omigosh-Fungus-Nightmare-Kill-It-Now, and I guess you can try them if you want, but seriously---I know what happens when I accidentally spill some of those "cures" on items inside or outside the house and I figured the risk was not worth the untested reward. If other folks want to venture into that realm, so be it, but at least fair warning has been given.

If one is going to go to all the effort of spraying, and it is WORK to spray, why not use the best product possible, one intended for the job, instead of experimenting with household cleaners? Why waste your time?

As an author and a reviewer in some of those vaunted "peer-reviewed" literature sources, I'm fully a member of the club that holds that "there is a lot of @#%$#@ (crap) in the literature and I put some of it there"

I wish we had the answers, but for most of the things in life, there is a lot of gray zone.

H.Kuska comment. I do not recall discussing with you my views of most published literature. In this thread please notice that I stated:

"Did he post the article to a gardening forum so that it could be discussed by others?"

And later:

"and have not been discussed in a forum of peers"

This second step (first step being published in a reviewed scientific journal) proved important in this thread, as Mike Rivers pointed out, the present concerns about the safety of triclosan (which once was considered so safe that it was used in toothpastes). See link below.
