I'm so sorry...Work. Work. Work.
I missed your question about Thiomyl.
NYOrchids is right...it's the same as Clearry's. (however it's spelled) Everyone has their own limitations with Chemicals. I work with Chemicals (and secretions) a lot in Nursing so I am very conscious about what I'm doing. You have to be.
I do like Thiomyl though because it does the job. No guess-work. You have to use some common sense though. Don't get it on your skin....wear gloves. Don't splash it in your eyes, wear goggles. I have a bucket that I use it in and that's all I use that bucket for. Chemicals.
The beauty of Thiomyl is that it's a systemic. Not just topical. Fungi can penetrate and go systemic and often reaches parts of plants that can't be accessed otherwise. Not all strains of fungi can be killed with peroxide and/or Listerine but Thiomyl WILL do the job. It's what I use when I have a plant that I'm not willing to take chances with. Since I have a few of those, when I make a batch, I soak anything suspicious. Don't use it around pets or children....You know....common sense.
You can buy it off Amazon in 8 oz containers. Use 1 tsp. per gallon. Soak the plant in the solution for 15 minutes. Repeat in one week. It doesn't affect flowering.
BUT, that said, Thiomyl works on Fungi. Sounds like you have a bacterial issue....Erwinia or Pseudomonas. Is there a weird smell? Slime? If so, go with liquid copper- 5-tsp./gal. Hope this helps.
