My Tropical plants have scale. Will Suspend SC kill scale?
Suspend SC is labeled for scale insects when they are still in the "crawler" stage. If the scale insects on your plants are past this stage or if you are not sure what stage they are in we recommend you contact your local cooperative extension office and speak to the mater gardener on staff. The master gardener can help with an accurate insect ID and also offer guidance on what will work best on the type of plant and insect you are dealing with.
