Can you identify this disease on my tropical plants?

Asked March 4, 2015, 12:35 AM EST

What disease is this? How can I treat it? It is white and sappy. It has gotten on a few of my tropical plants and has crippled my dwarf banana tree. I tried to use soapy water, but it only helped a little. What should I do?

Mealybugs are insects that have white, waxy filaments protruding from the tail end, and look as though they’ve been dusted with flour. Mealybugs are often found on the underside of leaves and below the soil surface on the main stem. Washing, physical removal, disulfoton, bifenthrin, permethrin, imidacloprid resmethrin, pyrethrins (at least two to three applications sprayed once every 10 - 14 days) are usually necessary.
