naphthalene acetic acid on mango trees

[Cythompson159@yahoo.com]

I found some info on this acid significantly decreasing fruit yields by decreasing fruit drop and works on mango trees. I can’t find info on how much, when and how frequently to use during flowering. Does anyone have info on this? I looked on amazon and they sell all different types with different concentrations of vinegar. I am interested in trying this on a lemon zest mango tree to see if it improves yield.

Note: one of the chemicals in this one is an herbicide(2-4-D):

Thanks, I did read those articles. They spurred me to ask the questions. Wish I could find some detail on  small scale use and opinions if safe long term.
