Can't get rid of Whitefly..... HELP!
I am having a huge problem with whitefly in my greenhouse especially on my pepper plants. I have tried using French marigolds which have not done anything to reduce numbers and yellow sticky traps didn't work.
I am a farmer so have got access to insecticides which I have been using (as a last resort) as seen by all the dead whitefly on the leaves of the plant. I don't want to spray them all the time but the damn things keep coming back!!!
what can I do to rid myself (and my plants) of these loathsome pests?
pleaee see pictures below.
thank you in advance
