About the Survey

The 2015 Agricultural Chemical Use Survey of wheat producers collected
data about fertilizer and pesticide use as well as pest management practices
in growing wheat. NASS conducted the survey in 16 states that together
accounted for 87 percent of the 54.6 million acres planted to wheat in the
United States in 2015, including 86 percent of winter wheat acres, 91 percent
of spring wheat acres,
Fig. 1. States in the 2015 Wheat Chemical Use Survey
and 88 percent of
durum wheat acres.
(Fig. 1 and box on p. 2)

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 wheat chemical
use survey in fall 2015.

Access the Data
Access 2015 wheat chemical use data,
as well as results from prior surveys
of wheat chemical use, through the
Quick Stats 2.0 database (http://

Data are for the 2015
crop year, the oneyear period beginning
after the 2014 harvest
and ending after the
2015 harvest. “Spring
wheat” does not
include durum.

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 nearly all acres
planted to durum
and spring wheat
(Table 1).

Pesticide Use
In the surveyed states, farmers used 42 different
pesticide active ingredients on durum wheat acres,
59 different ingredients on other spring wheat acres,
and 96 on winter wheat acres. These pesticide active
ingredients are classified as herbicides (targeting
weeds), insecticides (targeting insects), fungicides
(targeting fungal disease), and other. Herbicides were
the most widely used, applied to 61 percent of winter
wheat planted acres and nearly all durum and other
spring wheat (Fig. 2). Table 2 shows the most widely
used herbicides for each wheat type.

categories: prevention, avoidance, monitoring, and
suppression (PAMS). Table 3 shows the most widely used
practice in each category.
•	 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 observe or detect pests
through sampling or other forms of scouting.
•	 Suppression practices involve controlling or reducing
existing pest populations to mitigate crop damage.
Table 3. Top Practice in Pest Management Category, 2015
(% of wheat planted acres)
Prevention: No-till or minimum till
Avoidance: Rotated crops during last three
years
Monitoring: Scouted for weeds
Suppression: Maintained ground covers,
mulches, or other physical barriers
