Hi, I discovered 4 borers in my beautiful orange tree today. They are now dead, I have removed the dead bark, but the trunk is very close to being ring-barked. Is there anything I can do to maximise my tree's chance of survival i.e. help it in any wa

I am assuming you have found the larvae of a longicorn beetle in your orange tree. There is no chemical registered that I can recommend. It is important to clear away any insect frass and sawdust from the holes where the beetles have entered, and place a piece of wire into the hole to kill any larvae that may be there. You may notice some of the branches dying back as a result of the larvae being present. The damage branches should be pruned back to the green wood. Even though the tree has been ring barked, it may still survive. To increase the health of the tree, regular watering around the drip line along with an application of a slow release fertiliser will help the tree to recover. We suggest monthly applications of Yates Dynamic Lifter Liquid Concentrate. It's a organically certified fertiliser, which contains seaweed, blood&bone and fish meal to help developing new roots and restoring healthy growth. If you find after a little while that the tree is not improving, it might be wise to remove it and plant a new orange tree. Good luck in looking after your tree.
