Solution(By Examveda Team)

A more concentrated spray solution can be used in the case of low-volume sprayers.
Low-volume spraying was invented about 1950, particularly for the application of herbicides, in which 10 or 20 gallons, transformed into fine drops, would carry the pesticides. As it is sprayed in low volume thus the concentration of the solution should be high.
