Most notably, in 2009, the European Union prohibited aerial spraying of pesticides with a few highly-restricted exceptions in article 9 of Directive 2009/128/EC of the European Parliament and of the Council establishing a framework for Community action to achieve the sustainable use of pesticides, which effectively ended most aerial application ...
A smaller content of organic matter in the soil increases the amount of pesticide that will leave the area of application, because organic matter binds to and helps break down pesticides. [58] Degradation and sorption are both factors which influence the persistence of pesticides in soil.

Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
Ultra-low volume (ULV) application of pesticides has been defined as spraying at a Volume Application Rate (VAR) of less than 5 L/ha for field crops or less than 50 L/ha for tree/bush crops. VARs of 0.25 – 2 L/ha are typical for aerial ULV application to forest or migratory pests.
Pesticides are widely used by farmers to control plant pests and enhance production, but chemical pesticides can also cause water quality problems. Pesticides may appear in surface water due to: direct application (e.g. aerial spraying or broadcasting over water bodies) runoff during rain storms; aerial drift (from adjacent fields). [3]: p.2–22
The USDA and EPA are working together to examine new studies and how to improve scientific models to estimate the exposure, risk, and drift of pesticides. [34] The EPA is also working with pesticide manufacturers to ensure labels are easy to read, contain the correct application process and DRT for that specific pesticide.
Many countries have severely limited aerial application of pesticides and other products because of environmental and public health hazards like spray drift; most notably, the European Union banned it outright with a few highly restricted exceptions in 2009, [16] effectively ending the practice in all member states.
The Monterey County Weekly, in October 2007, reported that according to CDFA spokesman Jay Van Rein, the first two aerial applications over the Monterey Peninsula cost $3.7 million, with $3.1 million of that used to buy the spray products. [8] The November 2007 application was described as costing $2.7 million. [9]
