Does smoking induce flowering of mango trees or simply contribute to air pollution?

Rizal, PHL  April 29, 2013

Does smoking/smudging mango trees before flowering to induce its fruit bearing? (from E how) 

Or does it simply contribute to air pollution.  I think there too much smoking going on because of smudging of mangoes.

Does smudging really work?  Is this allowed by Clean Air Act?   No.  Under Part V111 of Section 1 of IRR of Clean Air Act.
