Hi All,

Is there any easy and effective way yet to rid green scales and white flies, especially, from guava trees? Neem oil doesn't seem to work well...

Thanks


gnappi:
I never had luck with neem oil either, but horticultural oil did better though it wasn't very effective on Guava and I wound up clearing scale by hand on guava and until recently I gave up owning most guava. I now have a Ruby supreme I'm going to have one more go at, I'll see what happens this time but I'll add Dr. Bronners home made insecticidal soap into the regimen.  .

Have you ever tried malathion-oil? I have never used it. It was recommended in old threads on this topic though.

Epicatt2:
Granular Imidacloprid is a systemic (spread udner a plant & watered in) and as a contact product sprayed on the affected plant and has worked well for me on my fruit trees and some ornamentals in my yard. 

Imidacloprid interrupts the ability of insects like aphids, scales, and mealiebugs to properly mature which causes them to be unable to reproduce.

It's not toxic to mammals/humans if if used as directed altho is is toxc to honeybees, so it is important wait to use it until after your plant has finished flowering.

OK ó HTH

Try using Azera. Itís OMRI listed and it kills soft scales and White fly. It contains Pyrethrins and Azadiractin. Itís worked extremely well for me. Iíve never had luck with regular Neem because it requires frequent applications before it becomes systemic.
