I have whiteflies in my high tunnel, and now also have the black sooty mold that is the result of the infestation. The variety that has the whiteflies and mold the worst is a Chinese dwarf called Qiyanai Huang. I sprayed it with a 1.5% peroxide solution, and a day later it looks much better, like most of the most has died.

The peroxide is too expensive. I was looking for a bleach alternative. Google led me to this old thread. I think it is worthy of a bump. I am going to try the 8 oz to 1 gal mixture to try and kill the sooty mold.
