3. Treating Lawn Areas
• Application should include wetting of
entire surface with no areas of over
concentration
• It’s very important to make uniform
applications to prevent leaving
bands and other damage from over
application
• Make sure to calibrate equipment
before application by knowing your
walking speed and how much
product is being applied based on
said speed

4. Equipment Used
for Application
• Involves two types of
application systems:
• Liquid (sprayers)
• Granular spreaders

5. Sprayers
• Rig-mounted sprayers
• Compressed air
sprayers

6. Rig-mounted Tank
Sprayers
• Work especially well when treating
large surface areas such as lawns
• Allows you to not have to refill the
tank over and over
• Tank size can range from 200– 600
gallons

7. Rig-mounted Sprayer
PPE & Mixing
• Make sure to wear all protective
equipment required by the product
label to protect from pesticide
exposure
• After mixing and before each
application make sure to run the
motor to mix pesticide through
continued agitation of the product.

8. Calibration Process Rig-mounted
Sprayers
• Measure an area of 1,000
square feet
• Add a specific amount of water
to the spray tank, treat the
area, and then measure the
amount of water remaining in
the tank
• The amount used is calculated
by taking your starting amount
and subtracting the remaining
amount left in the tank

Calibration

9. Granular
Spreaders
• Granular spreaders can be
used for large and small
areas
• When treating a large area,
you may choose to go with a
push spreader due to its
ability to hold more product
• In smaller areas like beds and
landscape areas a hand-held
spreader often works well

10. Improved
granular
application
techniques
will
include:
• Selecting the right equipment.
• Keeping the equipment in good working
condition.
• Calibrating the application equipment to:
• Prevent streaking of pesticides.
• Avoid a reduction in control with
pesticides.
• Apply proper amount of product.
• Selecting good quality product.

11. Calibration with Spreaders
• To calibrate your spreader for an application of fertilizer to your lawn:
• Determine the amount of fertilizer needed for 100 sq. ft. For example, the
fertilizer bag weighs 25 lbs. and covers 5,000 sq. ft.:
25 lbs × (100 sq ft ⁄ 5,000 sq ft) = 0.5 lb
• Place this amount in the spreader.
• Mark off the area. For a rotary spreader, use a 10-foot by 10-foot area
(100 sq. ft). For a single pass with drop spreaders, the length required
would depend on the width of your spreader: for a 1½, 2, and 3 foot
spreader use 66 2/3, 50, and 33 1/3 feet respectively.
• Apply using the suggested setting.
• Measure results and determine calibration rate.

12. Calibration includes:
• Calculating the amount of product needed.
• Mixing properly and safely.
• Adjusting the equipment to deliver the desired rate uniformly.
• Determining effective swath/overlap.
• Checking accuracy during operation.
• Detecting and correcting errors.
12

13. Importance
of
calibration:
• All spreaders should be calibrated
with the operator and the product
being used.
• Many product suppliers furnish
recommended settings and swath
width.
• Equipment manufacturers also make
setting recommendations.
13

14. Calibrating granular spreaders:
• Improves weed, insect,
and disease control.
• Lowers incidences of
using wrong amounts.
• Minimizes potential
problems to the
environment.
• Protects the safety of
people, pets and
non-target organisms
14

15. Ornamental
Treatments
• Most labels call for the
application to be at the
point of runoff on the
plant
• This can be very hard to
achieve due to the
different shapes and
sizes of ornamentals.
• A lot of care must be
taken in this area to
protect the plants
15

16. Compressed Air
Sprayers
• This type of spray is best suited for
smaller area treatments
• Ornamental treatments and weed
control are two great examples
• Most of these sprayers hold 5
gallons of product or less
• These sprayers may be pump style
or battery operated
16

17. Calibration
Procedure
(Backpack
Sprayers)
• Add a specific amount of water to the
sprayer.
• Spray the water as uniformly as possible
to the point of runoff.
• Take the amount of water left in the
sprayer and subtract it from the starting
amount in the sprayer in the beginning
17

18. Spot Treatment Sprayers
• Great for treating around
fences.
• Help control weeds in beds
and landscaping
• Calibrate sprayer same as in
compressed air sprayers,
but estimate area of spots
to be covered when figuring
amount of water and
product to add to spray
tank.
• Treat to point of run off.
18

19. Applying Products
Incorrectly:
• Without proper care, you may end
up applying incorrectly
• Misapplication of products is one of
the biggest issues in the industry
• This affects the quality of the
treatment, can damage the
property and can cost a company a
significant amount of money in
reapplication and/or damage
repairs
19

20. Product
Labels
• Product labels are of the
utmost importance in lawn
and ornamental applications
• The label is the law and must
be followed accordingly
• Don’t be the applicator that
thinks they already know the
label by heart
• Labels change periodically
and must be reviewed on a
regular basis
20

21. Label
Importance in
Pest and Disease
Control
• Always use the recommended
rates when treating disease
and pests
• The “nuke em” theory that
more is better actually works
against you
• Products have been
extensively tested and
approved by the EPA and are
proven to work in the
concentrations on the label

22. Client
Education
• Educate clients of their roles in controlling pests and diseases in
lawn and ornamental services
• Make sure the client understands the optimum watering
schedules and amount of water
• Lawn mowing and pruning of ornamentals is as important as
anything a L&O professional can do
• On each service visit let the client know their involvement and
role
• Set realistic expectations when services are performed

23. Review
• There are many types of equipment
and product to be considered when
performing a Lawn and Ornamental
application
• Knowledge of how the equipment
and products are vital
• Following product labels is
imperative to reaching optimal
levels of control
• Educating yourself and the client is
crucial to success since this is a
team effort
