"And why do some sprays seem to leave out plums and apricots- Bonide Fruit Tree Spray for example. "

It contains sulfur, and I can't speak for plums, but "cots" don't like sulfur.

Ah. So what kind of fungicide do you use for cots?

"Ah. So what kind of fungicide do you use for cots?"

Copper, and you can use Bonideî Citrus, Fruit & Nut Orchard Spray or Bonideî Fung-onil⢠Fungicide .
If you wish to use Bonide products. Most pros use other fungicides I think because of the low percentages of active ingredients in Bonide? Not sure? Seems like a decent company. I myself am still testing all these products for myself.
Monterey Fungi-Fighter is another I have seen used, but not sure if on cots? Also Spectracide.
Some of these may have the same active ingredients?
I would use at least 2 different fungicides, and where you can use them I would. where you cannot, use something else. Copper can be used on all, but best used in dormancy, but can be used at other times too.
Cooper is a must! It is also toxic to the soil (yet considered organic). I still use it anyway. It works!! Sulfur is also good, but not on cots.

Instead of product names, you should concentrate on the generic names of the active ingredients to know what you're really putting on your fruit.

The problem with the Bonide and Ortho products is that they're usually mixed with other stuff, and that's where problems can arise.

Thanks, Drew51. That was really helpful.
ltilton, What kind of problems can arise from combination products?

"The problem with the Bonide and Ortho products is that they're usually mixed with other stuff,"

Exactly what you want in a preventative. They are not meant for treatment, except the oil mentioned. The Fruit tree spray and the orchard spray are to be used like copper, as a preventative.
