Definition of ‘Chemical’

As a noun, the common definition of
chemical is a product or substance that is
produced or used in a process (reaction)
involving changes to atoms or molecules. The
term is sometimes defined more broadly as "a
substance".
 As an adjective, "chemical" means "of or
pertaining to chemistry". Chemistry is the
study of matter and its transformations.
In your life, you must use
common sense
Don’t run with scissors
 Swim with a “buddy”
 Get to the airport 2
hours early
 Don’t drink and drive
 Wash your hands after

have checks!

 Kneejerk reactions are
harmful to your thought
processes
 Never say “never”
 File a flight plan
 Read the manual
(RTFM)
If you are going to use any
kind of product on anything …

Read the label and follow directions
 Store the product in the original container,
locked away from children and pets
 Wear proper protection
 Do not mix ingredients (unless the label
allows it) or use more than directed
 Check the “use by date” – every time
 Do not “share” some with others
 Wash yourself, wash your clothes
 Know the number for the Poison Control
Center
American Association
of Poison Control
Centers
••••••••••••••••••••••••••••••••••
If you have a poisoning emergency, call
1-800-222-1222.
If the victim has collapsed or is not
breathing, call 911.
••••••••••••••••••••••••••••••••••
Read the label ….
… all of it!
What Else Does the Label
Tell You…
 What
clothing you need to wear to
protect yourself while using the
pesticide
Protective Clothing
 Long
sleeved shirt or protective suit such
as Tyvek
 Chemical Resistant gloves (not “rubber
gloves)
 Chemical Resistant boots (not rubber
boots)
 Goggles or face shield and hat
 Respirator for liquids
 Dust mask for dusty materials
 Wash hands and face afterwards, better
yet – shower off!
 Wash clothing separately from regular
Safety Glasses
Dust mask
Respirator with Filters
Chemical resistant gloves, boots, suit
Why Is Protective Clothing
Important?
 Chemicals
enter your body in 4 ways
 Skin
(dermal)
 Mouth (oral)
 Inhalation
 Eyes (also dermal)
 By
protecting these pathways you
reduce hazard to yourself
The Label Also Tells You…
 Active
ingredient of the product
 Dangers
to pets, wildlife or water
 What
plants it can be used on
 What
stage of the pest or weed it kills
 Pre
vs Post emergence/adolescent or
egg or adult
 Storage
and disposal information
And a whole lot more!
The MSDS (material safety data sheet)
Get one of these for each
product you use!
http://www.ehso.com/msds.php
http://npic.orst.edu/gen.htm
MSDS’ contain the label
information … and more!
How could the product hurt
you? How much does it take?
– Lethal Dose needed to kill 50%
of the affected population
 Expressed as milligrams per kilogram of
body weight of test subject
 LD-50


One kg = 2.20 lb
28,571 mg = 1 oz
 The
lower the number, the more toxic
LD-50 of some commonly used products:
Chemical
LD-50
Carbaryl (Sevin)
307
DDT
87
Malathion
885
Methoprene (JH mimic)
34,600
Nicotine sulfate
50-60
Pyrethrum
200
Rotenone
132
Sucrose (cane sugar)
29,700
Copper (metallic dust)
6,400
Caffeine
Insecticidal soaps
192
5,000-10,000
Sodium bicarbonate
4,220
Sodium chloride
3,000
Boric acid crystals
3,200
Signal Words – required on all
labels
Poison – Skull & Crossbones
 Danger – Highly Toxic, LD-50 (Oral) - 0-50
mg/kg
 Warning – Moderately Toxic, LD-50 - 50-500
mg/kg
 Caution – Slightly Toxic, LD-50 - >500 mg/kg
 Caution – Slightly Toxic, LD-50 - >5000 mg/kg


Signal Words are based on either material or carrier
(or both!)
The label gives you the Signal Word and a list of the ingredients
Routes of Exposure
– Exposure through the skin,
eyes, or any exposed areas of the body
... the most dangerous exposure for
rosarians
 Oral – Swallowing the material
 Inhalation – Breathing the material
vapors, usually occurs when mixing in
enclosed areas
 Dermal
Figure out what needs fixing:
 Leaves
showing symptoms? Of what??
 Petals showing symptoms? Of what??
 Stems and foliage dying? Why??
 Plain ol’ ugly rose? Can you replace
it?? Why not???
Think it through
– kills pests, general term
 Insecticide – kills insects
 Fungicide – kills fungi
 Miticide, Acaricide – kills mites (2 names
 Pesticide
in use)
– kills weeds and plants
 Rodenticide – kills rodents
 Homicide – kills people
 Herbicide
How does IPM fit with this?

Integrated Pest Management is a program of
monitoring and controlling insects and
disease with the least adverse effect on the
environment
 Figure out the problem before jumping to
conclusions
 Use biological controls where possible
 Start with the least toxic material and move
“up” if necessary
 Use ‘sustainable’ gardening practices
When you spray …
 Never
spray on windy days
 Do not spray on very hot days
 Spray early in the day so the plants can
dry off
 Spray enough material to cover entire
plant, undersides too!
 Use materials only to take care of the
problem or potential problem
 Lock up the pets until the spray dries
 Be a good neighbor
Avoid wasting:
 Money
 Energy
 Time
Use a tested and researched product!
Let someone else do the research and
test the product – don’t stir up a batch of
“homemade” spray material using a
recipe from the web, your grandma, the
guy next door to your auntie.
Disposal after use
Use up the mixture in the sprayer – on the
ground, the grass, the other plants
 Rinse the sprayer and spray out on the
ground, the grass, other plants
 Triple rinse the container and drain out on the
grass, the ground, other plants
 Wrap the container in newspaper and place
in trash - or  If your community has a Hazardous Waste
Collection site, take the containers to that site

YOU are responsible for:
 Your
own health and well-being
 Your family’s health and well-being
 The health of your garden
 Your pets
 … neighbors, friends, the earth …
As a CR:
Never recommend a product that is NOT readily available at a
garden store in your area, or is NOT labeled for use on ornamentals
Useful Information
 More
is not better – using more than
the label specifies:
 Is
a waste of pesticide, time and money
 Can
actually cause plant injury
 Can
contaminate the environment
 Pests
will not be controlled any faster
An easily understandable website for pesticide information
Let “Mother Nature” help!
She’s a “natural-born” killer …
…but most of all …
Be Safe!
