The detergent serves as a surfactant; oils can too. You probably don't need both.

I agree. If one uses vegetable oils, they will generally form soap when reacted with the sodium in either sodium or potassium bicarbonate, and this will help wet the surface. Detergent is probably not necessary. I prefer using Safer which is a potassium bicarbonate since plants need potassium anyway. But it seems like a pretty good recipe.

fwmosher said:BigAppleRoseGuy: "Peace" is one of my favourite HT's because of it's beauty, and of course the symbolization of the "supposed end of War(s)." Well not quite, but can't take that out on the rose. LOL. It is indeed a beautiful rose, and has some beautiful offspring as well, i.e. "Chicago Peace", "Glowing Peace" , "Red Peace" and there are others which elude me at this moment. Yes, it is a Black Spot magnet, but in your area, and here in mine, we should both be spraying weekly with an "anti-black spot" spray, amongst others-at the very least, a spray of: " Baking Soda Solution: The simplest solution is to add 1 rounded tablespoon of baking soda to a gallon of water, then add 2 tablespoons of horticultural or vegetable oil and 3 drops of Dawn dishwashing soap to 1 gallon of water. The oil acts as a thin barrier, making it more difficult for fungal spores to establish. The detergent helps the mixture stick to the rose, which is especially important when fighting powdery mildew since it tends not to wet very well – especially in advanced stages. The solution works best if applied once or twice per week. " Note: I do not add the detergent, because a good "detergent" fights oils, grime and dirt" etc. (just reminiscing fom some old soap commercial. Also, just as a thought, I never plant this rose out in any of my beds, but rather keep it on the back deck, potted, so I can watch it carefully and enjoy the beautiful blooms when they come, and they will! Get your camera ready (morning pics the best, I think)! Envious! Going to get at least two this weekend if I can find them! I tip my hat to you.

I have had good luck with this method also - however I replace 1/3 of the water with milk. Spoiled milk is OK to use also.
