pdfNURSERY AND FLORICULTURE
CROPS 2009
Overview
The National Agricultural Statistics Service (NASS)
Agricultural Chemical Use Program is the U.S.
Department of Agriculture’s official source of
statistics about on-farm and post-harvest fertilizer
and pesticide use and pest management practices.
In the spring and summer of 2010, NASS conducted
the Nursery and Floriculture Chemical Use Survey
to collect data about chemical use during 2009 for
19 nursery and floriculture production categories.
The chemical use results of the survey are based on
1,606 usable reports from operations in six program
states: California, Florida, Michigan, Oregon,
Pennsylvania and Texas.

Pesticides
In 2009, a total of 350 unique active ingredients
were used on nursery and floriculture crops in the
six program states. A total of 3.89 million pounds
of active ingredients were applied. In terms of total
amount applied, other was the most common
class of pesticide used on nursery and floriculture
crops.

A total of 677,500 pounds of insecticides was
applied to nursery and floriculture crops in the
program states in 2009. Based on total amount
applied, petroleum distillate was the most widely
applied insecticide accounting for nearly a third of
the total amount of insecticides used. Acephate
was the next most common insecticide at 87,700
pounds and third was petroleum oil at 76,200
pounds.

Insecticide
Of the total active ingredients applied, herbicides
accounted for 507,200 pounds, a decrease
from 929,600 pounds in 2006. Glyphosate
isopropylamine salt was the most widely used
herbicide, at 196,200 pounds. Oryzalin was the
second most commonly used herbicide with
83,300 pounds, followed by oxyfluorfen at 34,300
pounds.
Glyphosate isopropylamine salt was also the
most widely used herbicide in terms of percent of
operations using an active ingredient. Hexazinone
and isoxaben were the second most widely
used herbicides, both used by 9 percent of the
operations.

Herbicide
Herbicides
animal repellents, soil fumigants, biologicals/
pheromones, disinfectants and slug/snail baits.
The top two active ingredients were methyl
bromide and chloropicrin, with a total of 943,700
and 433,500 pounds, respectively.
Fungicides
As a percent of operations, daminozide,
paclobutrazol and uniconazole were the three
most common other chemicals used on nursery
and floriculture crops in 2009.
In 2009, growers applied 869,800 pounds of
fungicides to floriculture and nursery crops. The
three most commonly used were mancozeb,
at 367,400 pounds; chlorothalonil, at 159,700
pounds; and thiophanate-methyl at 90,400
pounds. These three active ingredients accounted
for 71 percent of the total pounds of fungicides
applied to nursery and floriculture crops.
The top two fungicides, in terms of percent of
operations, were chlorothalonil and thiophanatemethyl. Mefenoxam was third.
