Compatibility Test for Mix Components
Before tank mixing, always perform a simple jar test to
ensure compatibility of herbicides.
1. For 20 gallons per acre spray volume, use 3.3 cups
(800 ml) of water. For other spray volumes, adjust rates
accordingly. Only use water from the intended source at
the source temperature.
2. Add components in the sequence indicated in the Mixing
Order for Ground-driven and Backpack Sprayers section using 2 teaspoons for each pound or 1 teaspoon for
each pint of label rate per acre.
3. Always cap the jar and invert 10 cycles between component additions.
4. When the components have all been added to the jar, let
the solution stand for 15 minutes.
5. Evaluate the solution for uniformity and stability. The spray
solution should not have free oil on the surface, nor fine
particles that precipitate to the bottom, nor thick (clabbered) texture. If the spray solution is not compatible,
repeat the compatibility test with the addition of a suitable
compatibility agent. If the solution is then compatible, use
the compatibility agent as directed on its label. If the solution is still incompatible, DO NOT mix the ingredients in
the same tank.

Use Information
Mode of Action
Dimethenamid-P, the active ingredient in Tower® herbicide,
is a shoot growth inhibitor that controls susceptible germinating seedlings before or soon after they emerge from the soil.
Dimethenamid-P is a chloroacetamide herbicide belonging to
the herbicide mode-of-action Group 15 (WSSA)/Group K3
(HRAC).
Use Sites
Tower is a selective preemergence herbicide for the control
of certain annual grasses, annual broadleaf weeds and
sedges as they germinate in:
• Commercial ornamental production
• Landscape and grounds maintenance
• Tree plantations
• Turfgrass areas
Maintain continuous and constant agitation throughout application until spraying is completed. If the spray mixture is
allowed to settle for any period of time, thorough agitation is
essential to resuspend the mixture before spraying is
resumed. Continue agitation while spraying.
Tower may be applied as a soft-residual bareground treatment in the use sites described above.
Tower will not control emerged and established weeds.
A Tower treatment may be followed by any registered herbicide to control weeds not listed on the Tower label.
5
• Number of Nozzles - Use the minimum number of nozzles that provide uniform coverage.
• Nozzle Orientation - Orienting nozzles so that the spray is
released parallel to the airstream produces larger droplets
than other orientations and is recommended practice.
Significant deflection from the horizontal will reduce droplet
size and increase drift potential.
• Nozzle Type - Use a nozzle type that is designed for the
intended application. With most nozzle types, narrower
spray angles produce larger droplets. Consider using lowdrift nozzles. DO NOT use nozzles producing a mist
droplet spray.
Tank Mixing Information
Tower herbicide may be tank mixed with one or more registered herbicide products according to the specific tank
mixing instructions in this label and respective product labels,
provided that the product labels do not prohibit such mixing.
Follow the most restrictive label use directions and limitations
for all products used.
®
Physical incompatibility, reduced weed control, or plant injury
may result from mixing Tower with other pesticides (fungicides, herbicides, insecticides, or miticides), additives, or
fertilizers. Subsequent applications of postemergence herbicides may cause plant injury. Consult your local BASF dealer
regarding local tank mix options.
Application Height
Making applications at the lowest possible height (grounddriven spray boom) that is safe and practical reduces
exposure of droplets to evaporation and wind.
Additives
Spray adjuvants have little or no influence on the performance of Tower when applications are made prior to weed
emergence. However, several tank mixes with Tower could
require adjuvants to improve burndown of emerged and/or
established weeds. Therefore, surfactants or crop oil
concentrate may be used with Tower tank mixes applied to
emerged and/or established weeds. Follow the adjuvant
specifications on the tank mix partner’s label.
Swath Adjustment
When applications are made with a crosswind, the swath will
be displaced downwind. Therefore, on the upwind and
downwind edges of the application area, the applicator must
compensate for this displacement by adjusting the path of
the application equipment (e.g. ground) upwind. Swath
adjustment distance should increase with increasing drift
potential (higher wind, smaller droplets, etc.).
MANAGING OFF-TARGET MOVEMENT
Spray Drift
Wind
Avoiding spray drift at the application site is the responsibility
of the applicator. The interaction of many equipment-related
and weather-related factors determines the potential for
spray drift. The applicator is responsible for considering all
these factors when making decisions. Where states have
more stringent regulations, they shall be observed.
Drift potential is lowest between wind speeds of 3 to 10 mph.
However, many factors, including droplet size and equipment
type, determine drift potential at any given speed. Application
should be avoided below 3 mph because of variable wind
direction and high inversion potential.
NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how
they affect spray drift.
To minimize spray drift, the applicator should be familiar with
and take into account the following drift reduction advisory
information. Additional information may be available from
state enforcement agencies or the Cooperative Extension
Service on the application of this product.
Temperature and Humidity
When making applications in low relative humidity, set up
equipment to produce larger droplets to compensate for
evaporation. Droplet evaporation is most severe when conditions are both hot and dry.
Information on Droplet Size
The best drift management strategy and most effective way
to reduce drift potential is to apply large droplets that provide
sufficient coverage and control.
Temperature Inversions
Applications should not occur during temperature inversion
because drift potential is high. Temperature inversions restrict
vertical air mixing, which causes small suspended droplets to
remain in a concentrated cloud that can move in unpredictable directions because of the light, variable winds
common during inversions. Temperature inversions are characterized by increasing temperatures with altitude and are
common on nights with limited cloud cover and light-to-no
wind. They begin to form as the sun sets and often continue
into the morning. Their presence can be indicated by ground
fog; however, if fog is not present, inversions can also be
identified by the movement of smoke from a ground source.
Smoke that layers and moves laterally in a concentrated
cloud (under low wind conditions) indicates an inversion,
while smoke that moves upward and rapidly dissipates indicates good vertical air mixing.
Applying larger droplets reduces drift potential but will not
prevent drift if applications are made improperly or under
unfavorable environmental conditions (see Wind;
Temperature and Humidity; and Temperature
Inversions).
Controlling droplet size:
• Volume - Use high flow rate nozzles to apply the highest
practical spray volume. Nozzles with higher rated flows produce larger droplets.
• Pressure - DO NOT exceed the nozzle manufacturer’s
recommended pressures. For many nozzle types, lower
pressure produces larger droplets. When higher flow rates
are needed, use higher flow rate nozzles instead of increasing pressure.
6
Sensitive Areas
Ground Application (dry bulk fertilizer)
Spray drift from applying this product may result in damage
to sensitive plants adjacent to the treatment area. Only apply
this product when the potential for drift to these and other
adjacent sensitive areas (e.g. residential areas, bodies of
water, known habitat for threatened or endangered species,
or nontarget areas) is minimal. DO NOT apply when the following conditions exist that increase the likelihood of spray
drift from intended targets: high or gusty winds, high temperatures, low humidity, temperature inversions.
Tower may be impregnated or coated onto dry bulk granular
fertilizer carriers for preemergence surface applications.
Impregnation or coating may be conducted by either the inplant bulk system or the on-board system. When
impregnated onto some dry fertilizer blends, Tower may
exhibit a strong odor. Apply Tower within 30 days after
impregnation on dry bulk fertilizer.
Apply 200 to 750 pounds of the fertilizer and herbicide blend
per acre. Application must be made uniformly to the soil to
prevent possible plant injury and offer satisfactory weed control. Impregnated fertilizer spread at 1/2 rate and overlapped
to obtain a full rate will offer a more uniform distribution.
Wind Erosion
Avoid treating powdery, dry or light sandy soils when conditions are favorable for wind erosion. Under these conditions,
the soil surface should first be settled by rainfall or irrigation.
The actual minimum spray volume per acre is determined by
the spray equipment used. Use adequate spray volume to
provide accurate and uniform distribution of spray particles
over the treated area and to avoid spray drift.
Formula to determine the herbicide rate when using
dry bulk fertilizer applications:
fluid ounces or pounds
fluid ounces or
of herbicide per acre
x 2000 = pounds of herbicide
pounds of fertilizer
per ton of fertilizer
per acre
Application Methods, Equipment, and Rates
Tower® herbicide will provide most effective weed control
when applied by ground equipment and subsequently
incorporated into soil by rainfall, sprinkler irrigation, or by
mechanical methods prior to weed seedling emergence from
soil. Tower may be applied using water as the spray carrier.
Additionally, Tower may be impregnated on and applied with
dry bulk fertilizer. Sprayable fluid fertilizer as a carrier is not
authorized for use.
Incompatible Fertilizer Mixtures
Spraying Instructions
For preemergence control of the weed species (see
Table 12. Weeds Controlled), apply Tower at the use rates
stated in Table 1.
DO NOT impregnate Tower alone or with mixes on ammonium nitrate, potassium nitrate, or sodium nitrate fertilizers or
fertilizer blends. Single super phosphate (0-20-0) and triple
super phosphate (0-46-0) may be impregnated only with
Tower alone.
Application Use Rates
Uniformly apply with properly calibrated spray equipment in
sufficient water per acre to uniformly treat the area with a
spray pressure of 25 to 50 PSI. Suggested spray volumes
are 20 to 200 gpa for landscape and ornamental applications
and 10 to 200 gpa for turfgrass and other noncrop applications such as soft-residual bareground applications. Avoid
overlaps that will increase rates above those specified.

Application Instructions and Restrictions
• It is important that slit closure has been achieved so herbicide does not directly contact tree roots.
• DO NOT apply to newly transplanted seedlings until plants have been watered and
soil has been thoroughly packed and settled around roots.
• Directed or over-the-top spray applications can be made except at the time of bud
break.
• DO NOT apply at bud break under either application method.
Before treating a large number of plants, spray a few plants and observe for at least 2 months for plant damage prior to full-scale application.
Tank Mixes
For postemergence control of weeds, use tank mix combinations of Tower plus glyphosate, Finale® herbicide, or other
labeled herbicides. Refer to tank mix labeling for species authorizations. Determine rates for the tank mix partner from the
product labels of both Tower and partner herbicides prior to use. Caution must be exercised to prevent combination sprays
from direct contact with desirable foliage or injury may result. Tower plus diuron or simazine combinations will broaden the
weed control spectrum; however, use of combinations may restrict Tower usage in sensitive areas. Refer to manufacturers’
labels for specific use directions, precautions, and limitations before use, and follow those that are most restrictive.
Refer to Table 1 for use rates, Table 3 for list of ornamental (tree) species, and Table 12 for weeds controlled.
