WF can be tough to control, especially if you don/t want to use harsh chems.

Like I said, I-soap works best if you apply the treatment before an
infestation develops. At the first sign of WF, I spray, then spray again in
a few days, and again a few days later.

It might help to slightly increase the concentration of the I-soap so as to
get a better coating. The spray must coat the upper and lower surfaces of
the leaves and stems. It also has to be put on 'thick' to the point where
it drips from the leaves.
