Q/A #72 - Aphids on a Cape Sundew
QUESTION:
I'm not sure what this is on my Cape sundew. Possibly aphids? I watched your video on safe insecticides for some insight.
I sprayed it with orthene. It doesn't seem to be hurting the plant and only minimally moved over to my 2 other capes.
They seem to squish when I rub them between my fingers.
I'm guessing the product lasts about a month?
Anything else I should be doing?

RESPONSE BY JEFF DALLAS:
All of those little white dots are aphids. So yes, you have a bad aphid infestation, and a systemic insecticide like. Orthene (acephate) should do the job. As a systemic, it will last for about 20-30 days. Acephate is rather toxic, so spray in a well-ventilated area. You should also spray nearby plants to prevent the spread. As always, follow the directions recommended by the manufacturer.
Your sundew may take a bit of time to recover. If the infestation returns, you will need to spray again. If it returns for a third time, avoid using the systemic because you may create aphids that are resistant to the product. So, a last ditch effort would be to decapitate the plant. It will send up numerous new shoots from the stump and root system. That would also be a good time to change the soil, too.
