Blueberry, I recall some of the info you’ve shared here on gly. Good info.
I’ve been all over the place in terms of my concern of the trees using glyphosate. As it stands now I’m not too concerned about it. I’ve made enough mistakes, I think I’ve learned what I can and can’t get away with.
I’m using it primary on very vigorous peach trees with loads of organic matter to tie up the glyphosate. I add wood chips every year, so there is no lack of fresh organic matter.
I suspect the dynamic would be considerably different with things like dwarf apples on sandy soil.
I’ve not seen any effects on vigorous adult peach trees even if I hit the trunks or a little low hanging foliage with the boom sprayer, but I still don’t spray glyphosate after July 15th with a boom.
It’s always the young trees which seem extra sensitive to gly though.
