When they store glyphosate in trees, it could be attributed for fractures in barks and ultimately it could contribute to the entire tree’s health deterioration.

When they stack enough of them, the trees could even perish. As such, best is to use a shield to safeguard the trunk  when the tree is too young and when they have a fragile bark.
