Those black spots on the leaves appear to be hard scales; native honeyeaters often keep them under control on callistemons but their absent can lead to infestations that can be difficult to control. Ongoing spraying with a white-oil mixture is the usual treatment, but the coverage over the insects must be thorough. B.
I dunno, sometimes I type out a response/message press the right butoons, come back the next day and it hasn't worked. My fault or this sometimes unstable site? Anyway, I agree with Ted except I thought that black scale was 'hard' scale, not that it makes any difference the remedy is the same. My reference (Encyclopedea of Aus Gardening) says that native honey-eater birds usually keep the scales under control. Do you have any of those about, pennyw? B.
Hi funnelweb, I have just posted more photos in the other Australian Native Plants forum of more pests I've found on my callistemon - what do you think they are?
Its Psyllid. It common in lilly pillys.You can treat with Confidor before the new growth sprouts. It will kill off the scale to. Affected foliage can be trimmed off or left if u dont mind its appearance.
Yeah typical psyslid attack but I've a bit of problem with the size of the swellings: all up the pics suggest a heavier infestation with much larger swellings than normal psyslid attack. If I were you I'd think about total removal. You know I've a number of callistemons and, well a few minor problems but nothing like that.
