Sick Wurtz Avocado - Black marks / Burns

j.grey starts with ...
Hi Everyone,

I have a Wurtz Avocado in Adelaide about six months old. It was sunburnt as you can see over summer before I erected a shade tent for it. I have now noticed another dark mark on the trunk higher up though and I'm not sure it's sunburn. Reading other forum posts I think it could be the start of Anthracnose. I just put a liquid copper spray on as per directions on the bottle, any advice? I have a Bacon Avocado I got at the same time and it didn't get burned and is doing fine. Any help would be great.

Thanks
