can immonox disease control be mixed and sprayed safely with liquid soap or detergent for use on fruit trees?
I think liquid soap can be used with anything. It acts as a sticker/spreader, but isn't as good as a real sticker/spreader.
Others can confirm/correct my view.
There are a few things you can't spray with soap, e.g. sulphur, but most things are fine. Generally most things are safe to mix.
