WATER QUALITY CONSIDERATIONS IN
ORNAMENTALS PRODUCTION

Concern about the harmful effects of pesticides on
surface water and groundwater quality should
motivate nursery operators to select pesticides with
the least potential to cause water quality problems.
Many nursery operators live in rural areas near
where they and other operators grow ornamentals,
therefore, their personal water supply is susceptible
to contamination. Unfortunately, information that
allows operators to select pesticides less likely to
affect water quality has not previously been readily
available.

Our purpose is to provide information that can help
nursery operators select pesticides that will have a
minimum adverse impact on water quality. The
procedure considers the soil properties of the
application site, the mobility of pesticides in these
soils, and the toxicity of the pesticides in water to
humans and aquatic species. A proper selection will
decrease chances of adversely affecting surface
water and groundwater quality. Certain
combinations of soil and pesticide properties (along
with weather conditions) can pose a significant
potential hazard to water quality. Our goal is to
identify and avoid these circumstances. Information
contained in this report can help nursery operators
make better decisions about the pesticides that they
use. This document in no way endorses any
particular pest control product. All products must
be used in accordance with the label.


MATERIALS NEEDED TO USE THIS
PROCEDURE

To effectively use this procedure you will need the
following source materials:

1. A copy of the current IFAS Pest Control Guides
or other appropriate information sources that
identify pesticides that control specific pests.

2. A copy of your county soil survey report to
identify the soil types found in your nursery.

3. A copy of the Soil Science Fact Sheet entitled
"[Name of your county]:Soil Ratings for Selecting
Pesticides" for your county, available from your
county Cooperative Extension Office. The basis of
these ratings are given in the IFAS Extension


Circular 959 entitled "Soil Ratings for Selecting
Pesticides for Water Quality Goals," which is also
available from your county Cooperative Extension
Office.

Note: If your-county has not yet been mapped by
the Soil Conservation Service, you will need to
contact the local SCS office for a site evaluation and
determination of soil types and ratings for leaching
and runoff of pesticides.


IMPORTANT FACTORS THAT AFFECT
PESTICIDE SELECTION

How pesticides behave in the soil is determined by
many factors including properties of the pesticides
and of the soil at the application site. Some of the
factors that should be considered when selecting
pesticides with minimal potential for water quality
impacts are:

Pesticide properties 1) The organic carbon
adsorption coefficient, K, describes the relative
affinity or attraction of the pesticide to soil
materials and therefore its mobility in the soil. 2)
The biological degradation half-life, T, is a
measure of persistence of the pesticide in soil. 3)
The lifetime health advisory level or equivalent,
HALEQ, is a measure of health risk to humans of
pesticide contaminated drinking water. 4) Aquatic
toxicity, LCo, is a measure of the ability of the
pesticide to cause 50% mortality in aquatic test
species.

Soil properties 1) Hydraulic permeability is a
measure of the soils ability to allow water to
percolate through it. 2) Organic matter is
important for providing binding sites for pesticides,
thus reducing their mobility and increasing their
opportunity to be degraded by soil microorganisms.
3) Slope affects the potential for water to run off
the land surface.

Management practices 1) Pesticide application
frequencies and rates determine the total amount
applied. Lower frequencies and rates reduce the
potential for contamination. 2) Application
methods affect the amount of pesticide subject to
transport by water. For example, if applied directly
to the soil, there is a greater probability that more
of the product will be available for leaching or
runoff than if applied to the foliage. If the product








is incorporated into the soil, leaching may be the
most important loss pathway. Pesticides applied to
the foliage may be lost to the atmosphere,
decomposed by sunlight, or absorbed by the foliage,
thereby reducing the amount available for wash-off
and transport to water bodies. Irrigation practices
can also determine the loss pathways of pesticides.
Pesticides often move with water, so the less excess
water that is applied the less potential there is for
a pesticide to move past the crop root zone or to
run off in surface water. Rainfall or overhead
irrigation can wash off significant quantities of
pesticides from foliage immediately after
application.


INDICES USED TO SELECT PESTICIDES

Table 1 contains two important indices, the
pesticide leaching potential (RLPI) and the
pesticide runoff potential (RRPI). Both indices are
relative. For a given soil, these indices rank the
pesticides by their potential to move from the
application site by the indicated pathway (leaching
or runoff). The indices are based on the organic
carbon sorption coefficient and degradation half-life
values of each pesticide. Values for these
parameters have been taken from scientific
literature, technical manuals, and company product
literature.

The Relative Leaching Potential Index (RLPI)
defines the relative attenuation (reduction in mass
as it moves through the soil) of each pesticide in
soil, and therefore its potential to leach to
groundwater. Pesticides that are very mobile, for
example, those that have K,, values less than 100 in
sandy soils, or 50 or less in fine-textured soils
should be used with caution. There is some
uncertainty in the data used to calculate this index.
However, since the values are relative they can still
be used. It is important to realize that the smaller
the RLPI value of a pesticide the greater is its
potential to leach.


The Relative Runoff Potential Index (RRPI)
defines the relative immobility and availability of
each pesticide in soil, and therefore its potential to
remain near the soil surface and be subject to loss
in the aqueous phase or sediment phase of runoff.
There is some uncertainty in the data used


to calculate this index. However, since the values
are relative they can still be used. The smaller the
RRPI value of a pesticide the greater is its potential
to be lost in sediment runoff.

Table 1 also contains information on the toxicity of
pesticides to humans and aquatic species. This
information can be used as a secondary
consideration in the pesticide selection procedure.


The Lifetime Health Advisory Level or Equivalent
(HALEQ) provides a measure of pesticide toxicity
to humans. The lifetime health advisory level as
defined by the USEPA is the concentration of a
chemical in drinking water that is not expected to
cause any adverse health effects over a lifetime of
exposure (70 years), with a margin of safety. The
values in Table 1 are the USEPA lifetime health
advisory level, HAL, or an equivalent value,
HALEQ (denoted by a superscripted asterisk),
calculated using the same formula used by the
USEPA (HALEQ = RfD x 7000), where RfD is
the reference dose determined by the USEPA. For
non-carcinogenic pesticides the calculated HALEQ
should not differ by more than a factor of 10 from
the values forthcoming from the USEPA. The
HAL or HALEQ has units of micrograms per liter
(pg/l, or ppb). The smaller the value the greater is
the toxicity to humans.

The Aquatic Toxicity provides a measure of
pesticide toxicity to aquatic species. The values
given in Table 1 are the lethal concentrations at
which 50% of the test species die (LC5o ). Unless
otherwise noted by a lower case letter following the
value, the test species was rainbow trout. The
smaller the value the greater is the toxicity to
aquatic species.

Data for Ko, RLPI, RRPI, HALEQ, and aquatic
toxicity are given for the active ingredient (common
name) of a product. When using a product that is
a mixture of two or more active ingredients use the
RLPI, RRPI, HALEQ, and Aquatic Toxicity value
for the most restrictive active ingredient in the
mixture.

Important Note: The information presented in
Table 1 DOES NOT supersede or replace the
information on the pesticide container label or
product literature.








CRITERIA FOR MATCHING SOIL RATINGS WITH PESTICIDE INDICES


Pesticides with less potential to adversely affect water quality can be selected by matching the soil ratings and
pesticides using the following criteria:

PROCEDURE FOR SELECTING PESTICIDES
TO REDUCE ADVERSE WATER QUALITY
IMPACTS

A "Pesticide Selection Worksheet" is provided as a
convenient way to organize the information needed
to select pesticides to avoid water pollution by
pesticides in a particular production or management
unit. Instructions for using the worksheet are
outlined below. The function of the worksheet is to
match the soil leach and runoff ratings at the
application site with the pesticide RLPI (leaching)
and RRPI (runoff) indices and toxicity values given
in Table 1.


This will indicate the relative potential for pesticides
to leach or run off from a particular site and
consider the toxicity of the pesticides to humans or
aquatic life if the pesticides leach into groundwater
or if runoff enters surface impoundments or
streams. The last two columns are for recording the
nursery operator's choices and reasons for selecting
particular products.

Our intent is to provide a decision support tool for
the operator. The operator is responsible for
making the final choice. The completed worksheet
can serve as a permanent record of the selection
process used and decision made by the operator.

USING THE WORKSHEET


1. TARGET PEST: Correct identification of the
pests that need to be controlled is essential! Check
with knowledgeable experts and utilize competent
diagnostic laboratories so that a proper diagnosis
can be made. Misdiagnosis results in the wasteful
use of unnecessary pesticides and needless increases
in production costs. List confirmed pests in column
1 of the Pesticide Selection Worksheet.


2. RECOMMENDED PESTICIDES: Use the
current IFAS Pest Control Guides, or other
appropriate information sources to identify the
pesticides that control the pests of concern. List
these pesticides in column 2 of the Pesticide
Selection Worksheet.


3. PESTICIDE PROPERTIES: For each pesticide
listed in column 2 on the Pesticide Selection
Worksheet, copy the numeric value for KI, RLPI,
RRPI, HALEQ, and Aquatic Toxicity from Table 1
into columns 3, 4, 5, 6, and 7 of the Pesticide
Selection Worksheet.


4. SOIL PROPERTIES: Consult the County Soil
Survey Report soil map sheets to locate your
nursery and to identify the soils that occur in the
nursery. Use the Soil Science Fact Sheet entitled
"[Your County]:Soil Ratings for Selecting Pesticides"
(available from your county Cooperative Extension
Office) to determine the leaching and surface runoff
rating of the soils in your nursery. As you
determine the soil leach rating and the soil runoff
rating for each soil in the nursery list the soil
name, soil leach rating, and soil runoff rating in
columns 8, 9, and 10, respectively, of the Pesticide
Selection Worksheet.


5. SELECTION OF PESTICIDES: Using infor-
mation that you have compiled on the Pesticide
Selection Worksheet, select appropriate pesticides
using the selection criteria on page 4 to match soil
and pesticide properties. The selection made can
be recorded in column 11 and notes relating to the
selection can be recorded in column 12.


Notes:
1. If the pesticide product selected is a formulated
mixture or a tank mix, each active ingredient must
be considered. The most restrictive pesticide in the
mixture will determine the choice. Trade names in
Table 1 followed by (M) are formulated mixtures.

2. Sometimes there may not be a clear choice from
among the alternative chemicals available to control
a particular pest. In these cases, first order
screening using the RLPI or RRPI only can suffice.

3. Depth to groundwater and local geohydrology
may influence your final selection. Shallow
groundwater is more vulnerable to contamination.
Deep water tables with intervening impermeable
geologic layers are much less vulnerable.

4. Distance to surface water bodies may also
influence your final selection. Surface waters
adjacent to or near the pesticide application site are
more vulnerable to contamination than those further
away. If surface runoff from the application site
usually infiltrates into the soil off site before
reaching a surface water body, then the HALEQ
should be considered as the secondary screening
index.

5. If container grown plants are on plastic, the
water quality impact will be determined by the soil
rating where water leaves the plastic.
