Moses what are the constituents of your anti-fungal spray regimen?

I spray every two weeks, semi-religiously, all season long, beginning at when new spring growth after spring pruning, is up 2", then all the way to late October.

The Scott's lithium battery powered sprayer I got makes spraying less of a chore, but the sprayer is poorly designed: awkwardly balanced and prone to teeter, very heavy when full with 2 gal. of formula, about >20 lbs., and the stream is weak even with a full charge, but everyone reports this design fault who owns one.

There are only three spray settings on the nozzle, but I fiddled around and found a sweet spot that's satisfactory. The pressure needed to force out a decent spray from the nozzle causes the hose that attaches to the tank and spray wand to become stiff, creating mobility issues, increasing the risk of the tank teetering over. One full battery charge will last 2 sprayings for me, but barely last for 3 sprayings. The battery is encased inside a removable pump/pressurizing unit, fastened by screwing it into the top of the tank.

I still say that the Scott's Lithium Sprayer is decently usable, but not well designed.

Rifis, may you be the first to know that after more years than I can count right now, this past season, 2025, has unexpectantly and hopefully finally, been Rose Midge Fly FREE!!! I still can hardly believe my good fortune......a true blessing from above. You know the unrelenting dilemma I faced, year after year.

Somehow, the population both in my garden and evidently from the transient RMFs from the neighborhood have completely vanished. I did add Bayer Complete Insect killer, 1 tbl./gal. water, every spray session (mostly concentrating on black spot control), all summer long anyway, because you are probably aware that even with diligent spraying, a bad RMF infestation only means 90% control. Without fail, there will be damaged tips after every spray session, even with diligent spraying. The RMF is that insidious.

Not one single damaged growing tip was encountered all season long. I believe now that I could have dispensed with spraying for Rose Midge Fly by early August if I dared.

I have always included Bayer Complete Insect Killer along with fungicide in my spray mix. I just have to remember to add only 1 tablespoon per gallon of water of the insecticide, while both the Bayer and the Spectricide fungicide require 2 tablespoons of fungicide per gallon of water. It's easy to forget/confuse which gets what.

I alternate fungicides whenever I get to the end of a bottle. Then I switch to the other fungicide until that bottle runs out. This way the contents of a new, fresh bottle are always being used for a current spray session. When I am just about running out of one fungicide, I order the other brand in.

Spectricide Immunox comes only in a 16 oz./pint bottle. $16.99 is Amazon's current price. It's active ingredient, myclobutanil, 1.55%, is a thin, obnoxious smelling, maple syrup colored liquid. Your just sprayed roses will be smelly for a day or so, no more. 2 tablespoons per gallon of water is the recommended dilution rate. Once dry upon the foliage, it cannot be washed off. I only spray the leaf upper surfaces, but do so thoroughly. Immunox is not a systemic fungicide. It kills and prevents leaf surface located fungi. It is not absorbed into the rose's leaves. Every two week sprayings are recommended, which is my program, with occasional, unavoidable additional days per session.

Bayer Bio-Advanced Disease Control for Roses, Flowers and Shrubs, 32 oz./quart bottle. $12.09 is Amazon's current price. The active ingredient is Tebuconazole, 2.90%. It's absorbed systemically. There is no discernable odor to the sprayed foliage. The lightly thick, off-white colored liquid fungicide, is administered 2 tablespoons per gallon of water. When sprayed and the foliage surface becomes dry, it will not wash off. It is rainproof.

When combatting a fungus infection that has not previously been sprayed with a fungicide, spraying every week for a while, should get the infection under control. Every two week sprayings can begin thereafter.

Hope this helps.

Moses.

Rifis, your request is ready.

Moses.

Bump.

Moses.

Thank you.

When it is posted here, please let me know.

Rifis,

The answer to your request is posted right below your original inquiry on this post, just scroll up from here, and you will find it.

Moses.

No, it isn't there.

Could it be on a different thread?

Mad, did you just stay on THIS POST and simply scroll up from here to the second comment under COMMENTS? That long comment is my spray routine going into much detail.

Moses.

Mad is not mad, Moses.

I don’t see it either.

Neither before I sign in nor after I sign in.

I don’t doubt that you can see it, but we cannot see it.

Thank you, mad, for weighing in on this.

Why I can see it and no one else can is a mystery to me. I still have that abominable trouble posting because of the gremlins, whose treacherous waters I have learned to navigate. This plague has persisted for yeads now. Houzz should be ashamed of themselves....the bugs in their system are inexcusable.

Moses.

(If I don't put a period after my name at the conclusion of post the system goes into mayhem mode. I learned this period trick not long ago.)

When you write a post that Houzz rejects, it shows as posted for you in the thread that you see, but it didn't actually post. Whenever you make a post, always go to the main thread menu right after, and if it posted, the time of last post will be "just now". You probably had some word or abbreviation in your post that Houzz automatically flagged and rejected for no reason related to what you said. It happens. Just re-post it.

Moses: if you cannot see that mystery post when you are logged out of your account, but can see it when logged in, this would support the explanation susan provided.

Moses, one good thing about when Houzz does that to you is that you can copy and paste your post (that only you can see) and it works fine. So you don't need to re-write it. You might want to double check it to make sure you didn't use something like an abbreviation or something that their algorithm is programmed to reject. But sometimes it's just a mystery or a glitch.

Agree with susan.

Will require 45 seconds, if performed leisurely.

It would be a shame to let all that prior hard work go to waste.

You could also try translating you post into another language and posting it. That may avoid rejection. If it is successful, we could translate it back to a language in which we are fluent. Using Google Translate.

I will test my idea now, by posting this:

Why, I see the very long comment on fungi spray by Moses. that is very odd. Let me repost it.

Can anyone see my above repost of Moses on fungi spray?

I can’t see anything you reposted here, forever.

I can now see Moses’ response to my original question. It immediately follows my question. It was not visible last week. It indicates it was ”modified 10 days ago”.

Wow, this whole thing has been crazy!

Yeah it is really odd! I suspect it is due to the length of the post, however why some people can see but not others?
