What can be used to kill scale on Phrags?
The best product will be a systemic, since the adults are quite well protected from topical treatments by their shells, while they suck the juices out of the plant.
My preference is acephate.
FYI - Acephate is highly toxic to bees.
If you only have a few plants, repeated scrubbing with a soft brush and soapy water may do the job. If you have a substantial collection, acephate is better. Careful where you spray it (and it stinks, too).
orthene, which is a drench, is very effective on
scale. However, it is destructive to insects in
general. Unless you have a contained area like
a greenhouse, don't use it. Yeah, it stinks.
