Accidentally I sprayed Roundup herbicide to a betelnut tree. Now tree’s leaves are become yellow in color.
What I do? any solution?
If you sprayed the green foliage or any exposed, cut roots, or if you cut into the palm trunk and then sprayed the exposed tissue with Roundup herbicide, a week ago or more, and all the leaves are turning yellow, it is not good news and you may lose the palm.
But if you sprayed some herbicide on the external surface of the brown tree trunk, then it would not likely affect it and there may be another cause for the yellowing.
If all the leaves are yellowing, that's not good. But if it's only the lower palm fronds, then it may be natural yellowing and shedding of the oldest fronds, and just a coincidence with your herbicide spraying.
Drought stress could be another reason but not as likely.
