Vine growers; experience with Kaligreen?

anyone have experience with Kaligreen? Some questions;

  • How efective is it (one spraying versus multiple sprayings)
  • Given the issue of it's effectiveness only at high pH, anyone had any experience mixing it with their preventative (sulfur or other) sprays?

Also - given that Kaligreen is potassium bicarbonate, are there cheaper sources of the same material (quantity baking goods maybe?)

Ric,

I have no experience with baking soda but from what I read it doesn't seem to be very effective. Use one plant and experiment. Spray that one plant with Kaligreen and see what you get. I personally would recommend Oxiclean. It's cheap and it's an eradicant along with being a somewhat short lived protectant. The residue of soda ash is also a high pH (

11) and is the reason for its short lived protectant. Bordeaux Mixture is the same pH (11) and it's pH is a reason for it's effectiveness. All you can do is experiment. Let us know what you find.

Curious as to what it is that you've read that suggests it is not very effective. any links perchance? The few anecdotes I've had are either second hand (growers saying "so-and-so used it and it worled well") or retailers touting it.

I don't have any links off-hand. That's what I remember about the stuff. I think it's only good for powdery mildew. I would have tried it if I had read differently.
