Can Bora-Care be used on live trees in the spring to prevent ambrosia beetles from killing it?
Last spring a young pecan tree die because of them.
No, Bora-Care, like any other borate product cannot be used on trees or plants. Borate's will kill any living plant, shrub, grass or tree. You might want to look at Talstar P. It is typically used on trees for beetles. It cannot be applied directly on the product you are harvesting but it can be applied to the bark and tree and it will not harm the tree itself.
