I thought this was enough to mention it but I was talking to Ray Nesci again today. I am sure he must be getting sick of my calls

I have done a bit of a google search and all I can find is that maybe this is a resistance issue?
Don recommended Yates Anti Rot. Don said this stuff is non-toxic and you could bath in a bath full of it


Anti Rots active ingredient is Phosphorous Acid 200g/Land at about $15 for a 500ml bottle that mixes at about 5ml per Litre it is pretty cheap. It is systemic which means that it is absorbed by the leaves( I guess the roots as well) so it can be sprayed on or watered over the trees into the soil as a drench.
It works by boosting the defences of the plant and inhibits the growth of fungus.
It was interesting that Ray stated that this is what he uses as well. One application he stated was to prevent damping off in his seedlings. He agreed it would be great as a drench for any root rot issues. He also stated it can't be over done/
The only down side of Anti Rot is that it does not work as a dormant spray so I am still looking for a great non-toxic dormant fungicide.
So being non-toxic cheap easy on the environment cheap, versatile and highly recommended it sounds like maybe we should throw out the Fongarid??
Any one else with experience of these Fungicides?
