I dont neither have BER nor EB.

On BER I think liquid calcium is a better choice than eggshell. If there is any benefit in eggshell comes when it is broken down/decomposed.And that will takes months if not years.

I don't know anything about Immunox, but I use Daconil and Neem Oil sprays as fungicide. The latter is organic.

Good luck with the fight !

Glad to here you have no problems, I used to use Cooper Fungicide but a friend recommended Immunox so I thought I would try it, See there is some members here using it also and there is quit a few members using Daconil.

Jimmy, I think you may find it very useful to read the link below,a recent thread that makes a lot of good points about BER, I posted on July 4th, and you'll also recognize some names of folks here who do post quite often.

Here is a link that might be useful: BER

For the first time, I have had no Blossom End Rot this year. I planted the tomatoes late in an area that had been a compost heap years ago. The soil was very dry and I had to water frequently, every other day. After a couple of weeks, I ground up the egg shells from about one or two dozen eggs and whirled them in the blender with water that I then poured over the 4 plants. I have added crushed egg shells a few times since then, but not blenderized ones. Something did it.
