Hi everyone,
It’s been awhile since I’ve been on.
I’m wondering if I can defoliate a severely lace bug infested Azalea? I’m in South Coast NSW.
I have Contendor to spray it with but would prefer a more natural method before I do this.
Any and all advice would be appreciated
Thanks in advance.

Re: Azalea Lace Bug
Yes you can. If you defoliate and include a light prune that will remove them. Keep in mind however that as it is late in the season, it will regrow fine, however there may not be enough time for it to produce any flower buds before winter dormancy.

Re: Azalea Lace Bug
Remember too, that lace bugs are tricky to eliminate. They have three life stages (egg, nymph, and adult) and have multiple generations throughout the growing season. So, one defoliation or spraying is unlikely to get rid of them. They can overwinter as eggs.

Re: Azalea Lace Bug
Now is the last time to do a hard prune before flower buds set for the year.
Give them a good trim and get rid of affected leaves

Re: Azalea Lace Bug
Lace bug normally lay their eggs along the midrib or around the edges of the underside of the leaves. So if all of the leaves are removed reinfection is most likely to occur from adults coming from other infected plants. Also azaleas growing in the shade seems to have lower infection rates.Phil Rabl wrote: ↑February 16th, 2024, 7:58 am Remember too, that lace bugs are tricky to eliminate.

They can overwinter as eggs.
In any case, to really eliminate them you need to defoliate all of your azalea plants at the same time. The best time for this I found is in early December after most azaleas have finished flowering. This coincides nicely with regular azalea maintenance like pruning, wiring and repotting for both Satsuki and Kurume varieties.
