Fungicides

[Becka]

Does anyone know where I can get a good systemic fungicide without having to sell a few body parts (lol)?

Usually your local garden store or big box store like Lowes or Home Depot will carry them. Personally, I just go to a local small nursery. Never heard of it costing an arm and a limb though, wow!!! May I ask how much you've seen it on sale for?

Myclobutanil is a good systemic fungicide:
Systemic Fungicides for Fruit Trees | Garden Guides
You can buy it in retail garden stores as Spectracide Immunox:

Spectracide Immunox® Multi-Purpose Fungicide Spray Concentrate

You have to be cautious with systemic fungicides as many of them have plant growth regulator properties (thus can be phytotoxic) but I believe that myclobutanil is generally safe to use.

I also use Heritage DF (azoxystrobin) and Thiomyl (thiophanate methyl) which are said to be systemic. Heritage is expensive.

Here is a table of fungicides and bactericides but it does not include some of the newer items.

If you have Black Rot then mefenoxam is generally considered to be the gold standard of treatment. There are some other products now for treating Black Rot but they are all fairly expensive.
PP260/PP260: Black Rot of Orchids Caused by Phytophthora palmivora and Phytophthora cactorum
Mefenoxam 2 AQ (same as Subdue)

For non systemics I use Mancozeb and chlorothalonil and I just ordered some Captan.

Check out some of the biocontrol products containing fungi like Trichoderma harzianum. These are gaining traction in the hort and ag worlds for their ability to effectively suppress/eliminate pathogens without toxic chemicals (though they may have their own safety issues, obviously natural doesn't necessarily mean safe). Rootshield and Subculture B are a couple of the brand names I've seen, but I think there are some others out there. Not too expensive and reported by some knowledgeable individuals to work very well on orchids.
