2015 AGRICULTURAL CHEMICAL USE SURVEY

About the Survey

The 2015 Agricultural Chemical Use Survey collected data about fertilizer
and pesticide use as well as pest management practices in growing cotton.
NASS conducted the survey among cotton producers in 11 states that
together accounted for 94 percent of the 8.6 million acres planted to cotton
in the United States in 2015: Alabama, Arizona, Arkansas, California, Georgia,
Mississippi, Missouri, North Carolina, South Carolina, Tennessee, and Texas
(Fig. 1).

AGRICULTURAL
CHEMICAL USE

The Agricultural Chemical Use
Program of USDA’s National
Agricultural Statistics Service (NASS)
is the federal government’s official
source of statistics about on-farm and
post-harvest commercial fertilizer and
pesticide use and pest management
practices. NASS conducts field crop
agricultural chemical use surveys
as part of the Agricultural Resource
Management Survey.
NASS conducted the cotton chemical
use survey in fall 2015.

Data are for the 2015
crop year, the oneyear period beginning
after the 2014 harvest
and ending after the
2015 harvest.

Access the Data
Access 2015 chemical use data, as well
as results from prior surveys of cotton
chemical use, through the
Quick Stats 2.0 database

Fertilizer Use
Fertilizer refers to a soil-enriching input that contains one or more plant
nutrients, primarily nitrogen (N), phosphate (P2O5), and potash (K2O). For the
2015 crop year, farmers applied nitrogen to 78 percent of planted acres, at an
average rate of 79 pounds per acre, for a total of 503.7 million pounds. They
applied phosphate to 56 percent of cotton planted acres and potash to
42 percent of

Pesticide Use
The pesticide active ingredients used on cotton are
classified in this report as herbicides (targeting weeds),
insecticides (targeting insects), fungicides (targeting
fungal disease), and other chemicals (targeting all other
pests and other materials, including extraneous crop
foliage). Herbicides were used most extensively, applied
to 92 percent of planted acres. Other chemicals such as
dessicants were applied to 76 percent, insecticides and
fungicides to fewer. (Fig. 2)
Among herbicides, two different forms of glyphosate
were the most widely applied active ingredients,
followed by trifluralin (Table 2).

• Prevention practices involve actions to keep a pest
population from infesting a crop or field.
• Avoidance practices use cultural measures to
mitigate or eliminate detrimental effects of pests.
• Monitoring practices involve observing or detecting
pests through sampling, counting, or other forms of
scouting.
• Suppression practices involve controlling or reducing
existing pest populations to mitigate crop damage.
The most widely used prevention practice in growing
cotton was cleaning equipment and implements after
field work, used on 55 percent of planted acres. The
top avoidance practice was choosing crop or plant
varieties for their resistance to specific pests (55
percent). Scouting for weeds was the most widely used
monitoring practice (87 percent), and using pesticides
with different mechanisms of action was the top
suppression practice (33 percent). (Table 3)

Pest Management Practices
The survey asked growers to report on the practices
they used to manage pests, including weeds, insects,
and diseases. Cotton growers reported practices in four
categories: prevention, avoidance, monitoring, and
suppression (PAMS).
