Ground spraying produces less pesticide drift than aerial spraying does. [54] Farmers can employ a buffer zone around their crop, consisting of empty land or non-crop plants such as Evergreen trees to serve as windbreaks and absorb the pesticides, preventing drift into other areas. [55] Such windbreaks are legally required in the Netherlands. [55]
An obvious side effect of using a chemical meant to kill is that one is likely to kill more than just the desired organism.
