This stuff works and so far is the only thing I have found that kills the Sri Lankan Weevil.
When you spray it the next day the weevils are gone
You have to reapply as the next cycle of weevils morph out in 4-6 weeks.
The problem is the weevils also infests oak trees and once they are in an
area it's impossible to get rid of them completely. Keep the young mangos
clean so they can get going. I never spray this stuff on fruit or flowering trees.
If the young mango trees have flowers I would wait until you pull the panicles
then hit them with this poison
