Tiny white bugs or lichen on my Tahitian lime in a pot. In the tropics.
You can control them by spraying in winter with Yates Lime Sulfur. For all other times of the year, we recommend spraying thoroughly with Yates Nature's Way Citrus & Ornamental Spray. If the infestation is severe, you may need to use a blunt tool to scrape off the bulk of the scale, before spraying.
