Medium_image Need help with another grevillea

I don't know how to treat this problem, can you help please? I found a large grey catapiller & these ugly orange / brown spots on my grevillea trunk & branches.

Answer: Hi Lynne,
I can see one hole there at least so check there is no borer’s in there with a bit of wire, check the trunk for more holes and any frass that might be around. Use a product called Success Ultra for the caterpillars and if the leaves have got brown spots and you have dieback use Yates Antirot. I would probably prune that small little section off so water doesn’t get stuck and cause an issue. Grevilleas can get through most problems if they are growing in the full sun with a well drained soil
