How to get rid of whiteflies invasion

[David R. Rockhold]

Try Enstar 5E by Sandoz - it's a juvenile hormone. Most glasshouse whitefly
populations rapidly develop resistance to all insecticides but this stuff
works. We have also started keeping plants well staked and removed senescent
lower leaves to keep prime habitat to a minimum. Whatever spraying you do
must be thorough, persistent, and must reach the underside of the leaves
where the multiple stages co-exist.
