I have a old mandarin tree which is suffering from a borer which causes the bark to lift snd fall away.

Affects the main trunk and more substantial branches. You can see holes. The bark falls away with saw dust. How do I treat it?

Hi Jimmy,

Thank you for contacting Yates.

Unfortunately,as yet we don't have a product that is registered to treat borers in trees. To reduce and prevent borer infestation, we recommend improving the health of the plant and try to prune the stems/branches that are infested where possible. You could also make a lance out of a metal coat hanger and lance the borers down the hole/s, however, this is a rather crude form of control. Arborists may also be able to further assist you with advanced trees as they may have access to products for chemical control. 

 

Hope this helps and happy gardening 🙂
