The NASS Agricultural Chemical Use Program is USDA’s official source of statistics about on-farm chemical use and pest management practices. Since 1990, NASS has surveyed U.S. farmers to collect information on the chemical ingredients they apply to agricultural commodities through fertilizers and pesticides. On a rotating basis, the program currently includes fruits; vegetables; major field crops such as cotton, corn, potatoes, soybeans, and wheat; and nursery and floriculture crops. Read more . . .
Access the Data — Quick Stats
View and download current and past Chemical Use data from the NASS Quick Stats database.
- Choose the detailed database (Quick Stats 2.0) or try the Beta version of a simpler tool (Quick Stats Lite).
- In Quick Stats 2.0, under Program, select “Survey.”
- In both versions, under Sector, select “Environmental” and then make additional category choices.
Quick Stats provides complete results for all surveys conducted since 2009 and selected results for surveys conducted 1990 through 2008.
Since 2009, we release the results of chemical use surveys through Quick Stats. In addition, we provide the following materials for each survey: a Highlights fact sheet, a Methodology paper, and a set of Data Tables featuring commonly requested information.
- (updated July 2014)
In the next few years, we plan to conduct chemical use surveys on the following commodities.
Corn, potatoes, vegetables
Cotton, fruits, oats, soybeans, wheat
Corn, potatoes, vegetables

More...About the Agricultural Chemical Use Program
The program also collects information on the pest management practices farmers implement to reduce their dependence on agricultural chemicals (e.g., practices that make pesticides more effective or are an alternative to pesticides).
Historically, data were also periodically collected on chemicals used post harvest and in livestock production. Data through 2010 continue to be available.
About the Data
Each survey focuses on the top-producing states that together account for the majority of U.S. acres or production of the surveyed commodity. Data are available at the state level for all surveyed states, as well as at a multi-state level including all surveyed states. Data items published include:
- Percentage acreage treated, number of applications, rates of application, and total amounts applied of the primary macronutrients nitrogen (N), phosphate (P2O5) , and potash (K2O) as well as (since 2005) the secondary macronutrient sulfur (S). Available annually for field crops, intermittently for fruits and vegetables.
- Percentage acreage or production treated, number of applications, rates of application, and total amounts applied of the individual active ingredients composing all registered pesticides used. Active ingredients are classified as herbicides, fungicides, insecticides, or other (regulators, desiccants, etc.), according to the pesticide product classification. Rates and amounts applied are published in the acid or metallic equivalent, as applicable. Selected items available for all commodity programs.
- Percentage acreage or production treated, and percentage of total operations using a selection of pest management practices fitting under the PAMS (prevention, avoidance, monitoring, and suppression) classification. Selected items available for all commodity programs except livestock.
Who Uses the Data?
NASS collects information directly from growers, who participate voluntarily and on a confidential basis. The data are fact-based and report actual chemical use. The growers benefit directly and indirectly when public and private organizations rely on these accurate, timely data in making decisions about health, environment, safety, trade, and other issues. Some examples of how the data are used:
- USDA — to evaluate the safety of the nation’s food supply, assess risks and benefits, make decisions about product registrations, quantify the benefits of conservation practices, and market commodities internationally.
- U.S. Geological Survey (USGS) — to assess the quality of the nation’s streams, rivers, and groundwater; the impact of human activities; and the effectiveness of integrated pest management.
- Environmental Protection Agency (EPA) — to include actual use levels in product reviews. Without NASS survey information, EPA could assume higher levels are applied, thereby over counting chemical use, overestimating risk, and perhaps cancelling registrations for chemicals farmers rely on.
- State government agencies — to assess pesticides’ impacts on water quality and to evaluate the need for special pesticide registrations and emergency exemptions.
- Chemical manufacturers — to make research and development, marketing, and other business decisions.
- Commodity groups — to help establish industry trends and educate stakeholders.
- Public interest organizations — to educate the public and represent the public interest in policy discussions about pesticides and pest management.
- Researchers — to study important issues such as sustainability and the impact of integrated pest management.
Chemical Use Survey Partnerships
Currently, NASS conducts chemical use surveys for field crops in cooperation with the USDA’s Economic Research Service as part of the Agricultural Resource Management Survey program.
To maximize public benefits, reduce overlap, and minimize federal and state costs, NASS also develops partnerships with state agencies either to use data a state collects itself (for example, California) or to collect additional data for a state (examples include Minnesota, North Dakota, Washington, and Wisconsin).
