Hello, I have a case of whitefly infestation on my ficus hedge fence where the leaves have fallen approx 75%, and the remainder leaves will probably all be gone in the next week. Can the plants still be salvageable? If so, what is the type of treatment you recommend at this stage?
Also I have planted a new section of podocarpus hedge about a month ago in another area, and would like to do preventive treatment on them as well.
I have read your information on white fly control, but would like to use the most effective treatment, consider the stage of each problem area.
I recommend the BIFEN and IGR combination suggested in our WHITEFLY CONTROL ARTICLE. I’d hold off using the SPREADER STICKER since it can hurt weak plants which are no doubt more vulnerable once under the whitefly attack.
Treat all of the plants showing signs of the whitefly and for any you’d like to keep safe, treat them as well. Do a thorough treatment at least twice. Following the second application, you can then focus on infected plants only. I’ve been able to solve even the most infestation using this pattern and along the way, saved many other plants before they too were consumed.
