PURPOSE
The Postharvest Chemical Use survey provides detailed estimates
of postharvest chemical usage on selected farm commodities
by off-farm storage facilities. The survey addresses food
safety requirements of the Food Quality Protection Act.
COVERAGE
The population of interest is off-farm storage facilities
such as grain elevators, terminals, warehouse, and other facilities
that handle the commodities of interest during the survey
year.
CONTENT
Off-farm storage facility operators provide data on the quantity
of the commodities of interest handled during the year, the
amount of the commodities that were treated with chemical
applications, the name, amount, and method of application
of all chemical products applied, and data on their operation’s
pest management practices.
FREQUENCY
The Postharvest Chemical Use survey (PHCUS) is conducted
on an annual basis. The commodities surveyed change from year
to year. Commodities are selected to be consist with the Pesticide
Data Program, particularly the Agricultural Reseach Service’s
Pesticide Residue summaries. Commodities included in previous
PHCUS were apples, potatoes, off-farm corn and wheat storages,
off-farm oats and soybean storages, off-farm rice and peanut
storages, and off-farm oranges.
METHODS
Off-farm storage facilities that have reported positive stocks
during the year for the commodities of interest on other NASS
stocks or storage surveys are eligible to be sampled for the
PHCUS. A personal enumeration survey is used to collect the
information needed on the PHCUS. Given the complexity of data
collection for chemical applications, a time frame of approximately
two months is used.
PRODUCTS
In general, the Agricultural Chemical Usage, Postharvest
Applications results are published in the month of March following
data collection and summarization. Major tabulations include
percentage of the commodity treated with postharvest chemical
applications by commodity and state, total amount of active
ingredients applied by commodity and state, and the percent
of operations conducting specific pest management practices
by commodity and state.
USES
The Environmental Protection Agency (EPA), Agricultural Marketing
Service (AMS), Food and Drug Administration (FDA), and the
Economic Research Service (ERS) use the data published from
this survey for product registration issues, risk assessments,
benefit assessments, and for marketing commodities at state,
national, and international levels. As stated earlier, these
data are used in the Food Quality Protection Act (FQPA) decision
making process for product registration, re-registration,
and product alternatives.
