The white growth on your houseplants may be a fungus called powdery mildew or insects. Mealy bugs are tiny insects that are commonly found on houseplants. They are white with waxy filaments protruding from their tail ends. They look like they have a powdery coating. Mealy bugs can be confused with the powdery mildew fungus.

Powdery mildew white, thread-like fungal growth (mycelia) on infected plant parts. Columns of spores are produced on the mycelia, appearing as a white to gray powdery coating. The following fungicides are currently labeled for powdery mildew on various hosts: thiophanate-methyl (Cleary's 3336), Funginex, sulfur, Bayleton, and Bonide Remedy (potassium bicarbonate). Please go to the following sites to compare the white growth on your plants to mealy bugs and powdery mildew. http://www.extension.umn.edu/garden/insects/find/houseplant-insect-control/#mealybugs
