Hi there! I have a beautiful Alice DuPont and it is constantly getting White Fly!!! I've tries various sprays that the nursury people suggest and they still return!!
Please!! ANY SUGGESTIONS would be greatly appreciated!!
HELP!! White Fly!!!
Worm Gold is the best bet in our neck of the woods.
I'm not sure what Worm Gold is or how it works on Whitefly, but if you're not adverse to using chemicals, Marathon or Bayer Advanced Garden systemics (imidacloprid) applied to the soil will eliminate whitefly for (likely) the entire winter. If you'd like an organic and completely safe remedy, cold pressed neem oil applications, though slow acting, will work well by short-circuiting the pests ability to reproduce or complete metamorphosis. Deliver the neem in a spritz bottle with warm water and the neem (1 tsp per quart or liter) with a few drops of dishsoap to keep it emulsified. Keep shaking the container as you spray. I actually prefer to use it (neem) in a 50/50 rubbing alcohol mix along with the soap. The alcohol kills all the adults on contact, offering some knockdown.
