How long does it take for the smallest particle of insecticide spayed from an airplane to hit the ground?

Question

Specifics: in the heart of Havana City, at around 8 am (EST), all through the year. Insecticide mixed with petrolium.

Answer 1

In low level spraying programs most of the spray goes to the surface quickly. All the means of delivery are tightly controlled and administrated to protect the populace where the spraying is being done. You are in an area where an international (Canada and Cuba) program is being conducted to stop an epidemic of dengue fever by killing mosquitoes. Visit the websites below for additional information.
