Preemergence Herbicides for Use In Ornamentals'

Robert H. Stamps, Diane K. Rock and Jeffrey G. Norcini2

Preemergence herbicides, by definition, are herbicides that are applied prior to weed
seed germination. Control of weeds using preemergence herbicides is most successful
when the correct herbicide is applied in the correct manner to a weed-free growing
medium prior to weed seed germination. In field or landscape situations, the soil should
be freshly tilled, and large clods of soil broken up. The growing medium, whether soil or
soilless, should be settled and firm at the time of herbicide application.

Herbicides should be applied uniformly to the target area and then immediately
incorporated into the growing medium. Uniform herbicide coverage is dependent on good
application technique and, for mechanized application, on well-maintained and calibrated
equipment. Incorporation is generally employed to reduce herbicide losses from volatility
and photodecomposition, but it also serves to activate some herbicides. It is commonly
accomplished by applying water using overhead irrigation, often about 0.5 inch [1.2 cm],
after the herbicide has been applied. Herbicides can also be mechanically incorporated by
mixing the herbicide into the top layer of the growing medium, generally to a depth of 1-3
inches [2.5-7.5 cm]. Recommendations regarding the depth of mechanical incorporation
and/or the amount of irrigation water to apply to activate/incorporate the herbicides should
be followed carefully in order to minimize the possibility of crop injury.

Mention of a commercial or proprietary product or chemical does not constitute a recommendation or warranty of the product by
the authors or the University of Florida, Institute of Food and Agricultural Sciences, nor does it imply its approval to the exclusion
of other products that may also be suitable. Products should be used according to label instructions and safety equipment required
on the label and by federal or state law should be employed. Users should avoid the use of chemicals under conditions that could
lead to ground water contamination. Pesticide registrations may change so it is the responsibility of the user to ascertain if a
pesticide is registered by the appropriate state and federal agencies for an intended use.

Many of the preemergence herbicides used in ornamentals are formulated as granular
materials and should be applied evenly over the treated area. Avoid applications to moist
foliage or to whorled or other foliage types that will accumulate and trap the granules.
Application equipment used to broadcast these formulations should not grind the granules or
increase the amount of dust; this may generate potentially dangerous conditions to nearby plants
and people. Use materials that have been screened of fine particles, if available.

For liquid applications, spray pressure should be constant and adequate to maintain
proper spray pattern for uniformity and ensure droplet penetration through the plant canopy.
Excessive pressure can lead to drift and damage to non-target plants. Spray volume should be
sufficient for thorough coverage. Herbicides should be thoroughly mixed (agitated) in spray
tanks to obtain uniform results, and spray nozzle openings (orifices) should be checked regularly
and replaced when wear becomes evident. Spray adjuvants that enhance coverage, penetration
and/or persistence of herbicides can be added to some spray mixtures, especially if the mixtures
are applied so that the crop foliage is not treated. Test spray solutions that contain any new
adjuvant for phytotoxicity on a small part of your crop, just as you would test any new pesticide.

Chemigation is a special type of liquid application in which herbicides are applied using
the irrigation equipment. It is the least labor-intensive method to apply herbicides; however, few
herbicides are labeled for application in this manner (see Table 1). In addition, some types of
irrigation systems (e.g., drip) do not apply water to all areas that need to be treated and/or do
not have adequate uniformity for this use. Herbicide formulations applied through irrigation
systems must not clog nozzle orifices. Florida and other states have laws that require that safety
equipment must be provided if chemicals are to be injected into irrigation systems. Some of the
equipment necessary to prevent contamination of the water supply includes check valves,
vacuum breakers, low-pressure drains, shutoff valves, remote chemical storage tanks and
interconnected power supplies to injector and irrigation pumps.

Liquid herbicides should be measured volumetrically, i.e., using measuring cups,
graduated cylinders, etc. Since dry pesticides vary in density, it is not possible to give accurate
volumetric conversions across brands and formulations so those formulations must be weighed.

It is a good practice to keep records of all pesticide applications, even of nonrestricted use
pesticides including EPA registration and product lot numbers. These records can be useful
for planning future weed control measures. In addition, they can be invaluable if crop damage
occurs.

Regardless of the herbicide or application method used, it is strongly recommended that the effects
should be evaluated against untreated controls under your particular conditions before treating large
areas. This is especially important when there is a statement on the label permitting use of the product
on an ornamental not specifically listed on the label. Treat a limited area or number of plants and
wait 2 to 3 weeks, or longer if the label recommends, for any phytotoxic effects to appear. Be
aware that the larger the area treated, the more likely that phytotoxicity may occur, especially
due to volatilization. Also, damage may not occur the first time a herbicide is applied, but may

show up with repeated applications. Several formulations of a herbicide may be available with
varying concentrations; consequently, recommendations on the manufacturer's label should be
followed explicitly. These herbicides formulations are labeled for application in certain
environments (outdoors, in shadehouses and/or in greenhouses) and specific locations
(containers, field and/or landscape) and can only be applied in those specified environments and
locations.

Although most preemergence herbicides labeled for use in ornamentals have relatively low
acute mammalian toxicities, they are potentially dangerous if handled improperly and, therefore,
the safety precautions on the labels) must be followed. Read the entire label, including the small
print, before buying or using the herbicide. Wear personal protective equipment (PPE) and
comply with restricted entry intervals (REI) (see Table 1). Keep the telephone number and
address of the nearest County Poison Control Center listed in a convenient location in case of an
accidental poisoning. Have clean copies of herbicide labels and material safety data sheets
(MSDS) available to be taken to the Poison Control Center or hospital in the event of an
emergency. If a herbicide is labeled for use specifically in a particular state [for example, 24(c)
Special Local Need labeling in Florida], obtain a copy of the supplemental label from your
supplier when you purchase the product; otherwise, you will be using it illegally.

Many of these herbicides have low solubilities in water and are quite strongly held to
binding sites in growing media and are, therefore, not readily leachable. However, the relatively
long persistence (long degradation half-lives, T,) of some of these products creates the potential
for leaching losses to still occur with potential effects on ground water. Relative leaching
potential indexes (RLPI) for the listed products range from 3 (high potential to leach) to >2,000
(low potential for leaching, very immobile) and are given, along with relative run-off potential
indexes (RRPI), in Table 1. RRPIs range from 1 (high potential to be lost in runoff) to 333 (lower
run-off potential). For more information about pesticide leaching and run-off, read Managing
Pesticides for Ornamentals Production and Water Quality Protection (University of Florida, Institute
of Food and Agricultural Sciences, Cooperative Extension Service, Soil Science Department
Circular 991, available at http://edis.ifas.ufl.edu/).

As an aid to help delay the selection of herbicide-resistant weeds, the herbicide group to
which each product belongs is listed in Table 1. The groups are based according to primary
sites/modes of action (Weed Technology 11:384-393 [1997]) and can be used to select herbicides
that have differing sites/modes of action. Repeated use of a herbicide or herbicides having the
same sites of action can, over time, cause development of weeds resistant to those herbicides.

Store herbicides in their original labeled containers, out of reach of children. All pesticides
should be locked in secure facilities. When containers are empty, rinse with water at least three
times and pour the rinse water into the spray tank. Dispose of empty containers promptly and
safely (according to local, state and federal disposal laws).

In Table 2, weeds are listed alphabetically by scientific name and along with the
preemergence herbicides that control (C), suppress (S) or do not control (N) each weed. Table

3 is similar except that the weeds are listed alphabetically by common name(s). The information
in these tables is derived from product labels, and published and unpublished research results.
A herbicide may provide variable weed control depending on soil, irrigation and other variables.
Where the weed entry in the tables lists only a genus, the labels must be checked to see which
species in that genus are controlled by each herbicide.

Table 4 lists the tolerances of ornamentals to preemergence herbicides, with the table
subdivided into Trees and Shrubs, Groundcovers and Vining Plants, and Annuals and Perennials. The
plants are listed alphabetically by scientific name. This information is derived from product
labels. It is only presented as a guide and does not imply that a herbicide can be used in or
around that ornamental species in all sites (nursery, landscape, greenhouse). In Table 4, Y
indicates that the crop is on product label and N indicates that the product should not be used
on the crop. Please note that not all plant species and cultivars listed on the herbicide labels are
included in the table and some plants are listed in the table even though, at the current time,
they are not listed on any of the herbicide labels. Hopefully, research and future label changes
will help alter this situation for this latter group of plants.

To help in situations where the reader does not know the scientific name of the crop, Table
5 is included. It lists the common names of crops beside their scientific names; however, readers
should be aware that the same common name may be used for more than one plant so the true
identity of the crop should be ascertained before herbicides are applied.

When selecting a herbicide, both of the factors listed below must be determined to legally
use a herbicide in or around an ornamental species; the information below is on the product
label:

1. Determine the tolerances of specific species, varieties, or cultivars, if
applicable,
AND

2. Determine which sites the herbicide can be used on, that is nursery
(container or field); landscape (commercial, public, or residential);
enclosed greenhouse.
