Pests
A pest is anything that:
• competes with humans, domestic animals, or crops for food,
feed, or water,
• injures humans, animals, crops, structures, or possessions,
• spreads disease to humans, domestic animals or crops.
• annoys humans or domestic animals.
Pests can be placed in four main categories:
• insects (and related animals),
• plant disease agents,
• weeds, and
• vertebrates.
OSU
PSEP
Integrated Pest Management (IPM)
• Integrated pest management (IPM) has
evolved to develop management strategies that
incorporate all aspects of the crop and pest
ecosystem to economically manage the crop.
In the integrated management approach,
management strategies such as resistant
varieties, crop rotation, cultural practices and
use of beneficial organisms need to be
considered before considering chemical
control.
OSU
PSEP
Economic Thresholds & Economic
Injury Level
• The economic injury level is defined as the
point at which a pest population begins to
cause economic damage
• The point that induced control measures must
be applied to prevent the pest from reaching
the economic injury level is call the economic
threshold or action level.

Insects
• All insects in the adult stage have two physical
characteristics in common. They have three
pairs of jointed legs, and they have three body
regions - the head, thorax, and abdomen.
OSU
PSEP
Insect Like Pests
• Mites, ticks, spiders, sowbugs, pillbugs,
centipedes, and millipedes resemble insects in
size, shape, life cycle, and habits, but are not
insects. Pest species usually can be controlled
with the same techniques and materials used to
control insects.
OSU
PSEP
Plant Diseases
• A plant disease is any harmful condition that makes a
plant different from a normal plant in its appearance
or function. Plant diseases caused by biological
agents (pathogens) are of primary interest to pesticide
applicators because they often can be controlled with
fungicides or bactericides. Pathogens include:
• fungi,
• bacteria,
• viruses
• mycoplasmas
• nematodes.
Wheat Leaf Rust
OSU
Sclerotinia Blight
PSEP
Plant Diseases
• Pathogens that cause plant disease are
parasites that live and feed on or in host plants.
They can be passed from one plant to another.
Three factors are required before a pathogenic
disease can develop—a susceptible host plant,
a pathogenic agent, and an environment
favorable for development of the pathogen.
This is called the disease triangle

Weeds
• Any plant can be considered a weed when it is
growing where it is not wanted. Weeds are a
problem because they reduce crop yields,
increase costs of production, and they reduce
the quality of crop and livestock products. In
addition, some cause skin irritation and hay
fever, and some are poisonous to man and
livestock. Weeds also can spoil the beauty of
turf and landscape plants. Some weeds are
host to insect pests and plant diseases.

Vertebrate Pests
• As in insect pest control, techniques for control
of vertebrate pests depend on whether the pest
problem is indoors or outdoors.
• Indoor vertebrate pest control usually is aimed
at preventing pest entrance and eradicating pest
infestations. Nearly all indoor vertebrate pests
are rodents, but others, such as bats, birds, and
raccoons, also may require control.
• Outdoors, the strategy usually is to suppress the
pest population to a level where the damage or
injury is economically acceptable.
OSU
PSEP
Pesticides
• Pesticides are chemicals used to destroy,
prevent, or control pests. They also include
chemicals used to attract or repel pests, and
chemicals used to regulate plant growth or
remove or coat leaves.

OSU
Insecticide: controls insects and
other related pests such as ticks
and spiders.
Miticide: controls mites.
Acaricide: controls mites, ticks,
and spiders.
Nematicide: controls
nematodes.
Fungicide: controls fungi/plant
diseases.
Bactericide: controls bacteria.
Herbicide: controls weeds.
Rodenticide: controls rodents.
Avicide: controls birds.
Piscicide: controls fish.
• Molluscicide: controls mollusks,
such as slugs and snails.
• Predacide: controls vertebrate
pests.
• Repellent: keeps pests away.
• Attractant: lures pests.
• Plant Growth Regulator: stops,
speeds up, or otherwise changes
normal plant processes.
• Defoliant: removes unwanted
plant growth without killing the
whole plant immediately.
• Desiccant: dries up plant leaves
and stems and insects.
•
Antitranspirant: coats the leaves
of plants to reduce unwanted
water loss (transpiration).

•
•
•
•
OSU
•
•
Protectants: applied to plants, animals, structures, and
products to prevent entry or damage by a pest.
Sterilants: makes pests unable to reproduce.
Contacts: kills pests simply by contacting them.
Stomach poisons: kill when swallowed.
Systemics: taken into the blood of an animal or sap of a
plant. They kill the pest without harming the host.
Translocated herbicides: kill plants by being absorbed by
leaves, stems, or roots and moving throughout the plant.
Fumigants: gases that kill when they are inhaled or
otherwise absorbed by the pest.
Anticoagulants: prevent normal clotting of blood.
Selective: more toxic to some kinds of plants or animals
than to others.
Nonselective: toxic to most plants or animals.
Pheromones: affect pests by changing their behavior.

OSU
PSEP
Formulations
• The active ingredients in a pesticide are the chemicals that
control the target pest. The pesticide product you purchase is
rarely made up only of active ingredients. Usually the
pesticide is diluted in water or a petroleum solvent, and other
chemicals are added before the product is offered for sale.
These other chemicals may include wetting agents, spreaders,
stickers, extenders, or diluents. They usually make the product
safer, easier to apply, more convenient to handle, and more
accurate to measure. This mixture of active and inert
(inactive) ingredients is called a pesticide formulation. Some
formulations are ready for use. Others must be further diluted
with water, a petroleum solvent, or air by the user before they
are applied.
OSU

PSEP
Adjuvants
• An adjuvant is an inert material
added to a pesticide formulation
or tank mix to increase the
effectiveness of the active
ingredient. Most pesticide
formulations contain at least a
small percentage of additives.
Some applicators add additional
adjuvants while mixing for special
applications. Some product labels
may caution the user against
adding adjuvants.
OSU
PSEP
Adjuvants
• Wetting agents—allow wettable powders to mix with water and stick on
plant or animal surfaces.
• Emulsifiers—allow petroleum-based pesticides (EC's) to mix with water.
• Invert emulsifiers—allow water-based pesticides to mix with petroleum
carrier.
• Spreaders—allow pesticide to form a uniform coating layer over the
treated surface.
• Stickers—allow pesticide to stay on the treated surface.
• Penetrants—allow the pesticide to get through the outer surface to the
inside of the treated area.
• Foaming agents—reduce drift.
• Thickeners—reduce drift by increasing droplet size.
• Safeners—reduce phytotoxicity of pesticide to protected crop.
• Compatibility agents—aid in combining pesticides effectively.
• Buffers—allow mixing of pesticides of different acidity or alkalinity.
• Anti-foaming agents—reduce foaming of spray mixtures that require
vigorous agitation.
OSU
PSEP
Compatibility
Two or more pesticides that can be mixed together to control a wider range of
pests with a single application are said to be compatible with each other.
Sometimes the pesticides are formulated together by the manufacturer, but
the applicator often must mix separate formulations in the tank. It is
important to remember that not all pesticides work well in combination.
Pesticides that are not compatible can cause:
• loss of effectiveness against the target pest,
• injury to the treated surface (phytotoxicity in plants, toxicity in treated
animals, stains or corrosion on treated surfaces),
• separation of ingredients into layers or settling out of solids.
Some pesticide labels list other pesticides with which the product is
compatible. Pesticide publications, land grant universities, and
independent experts can supply information based on local experience.
OSU
PSEP
Tank Mix Compatibility
• Some Labels may have
precautions about mixing
certain types of pesticides
together. Mixing certain
herbicides together may
reduce activity or mixing
certain insecticides and
herbicides together could
cause crop injury under the
right conditions.

Section III Labels & Labeling
• EPA Approval of Pesticide Labeling
• Parts of the Label
• Reading the Label
OSU
PSEP
EPA Approval
• No pesticide may be sold in the United States until the U.S.
Environmental Protection Agency (EPA) has reviewed the
manufacturer’s application for registration and determined that
the use of the product will not present an unreasonable risk to
humans or the environment. As part of this product
registration process, EPA has certain labeling information
requirements and must approve all language that the
manufacturer proposes to include in the product labeling.
• . Pesticide users are required by law to comply with all the
instructions and directions for use in pesticide labeling.
When pesticides are not being uses according to label
directions, they are being used illegally.
OSU
PSEP
Types of Registrations & Labels
• Federal EPA registrations are the most common. Most pesticide uses are
registered this way. Look for the official EPA registration number (which
must appear on the label) to be sure you are buying an approved product.
• Special local needs registrations (known as SLN or 24(c) registrations)
allow States to further control how the pesticide is used in their jurisdiction,
including registering additional uses or adding limitations for a federally
registered pesticide
• Emergency exemptions from registration are used when an emergency
pest situation arises for which no pesticide is registered. If both Federal
and SLN registrations would take too long to enact, an emergency
registration can be used. Known as “Section 18 exemptions,” these
registrations are handled by the highest governing official involved -usually a State governor or Federal agency head. This provision allows a
pesticide product to be sold and used for a nonregistered purpose for a
specified period of time.
OSU
PSEP
Classification
• Restricted Use Pesticide
• General Use Pesticide
• EPA registers every use of every pesticide as either
“restricted use” of not restricted use. Many times all
the uses of a particular formulation are registered as
restricted use or all are unclassified. Sometimes,
however, certain uses of a formulation are restricted
use and other uses of the same product are not
registered as restricted use. In these cases, the
directions for use for the two registrations must be
clearly separate from one another by each product
having entirely different packaging and labeling.
OSU
PSEP
Restricted Use Pesticides (RUP)
A pesticide, or some of its uses, is registered as
restricted if it could cause harm to humans
(pesticide handlers or other persons) or to
the environment unless it is applied by
certified applicators who have the
knowledge to use these pesticides safely
and effectively. The word “use” un this
phrase is a general term -- it refers to such
activities as:
• application,
• mixing and loading,
• transporting, storing, or handling pesticides
after the manufacturer’s seal is broken,
• care and maintenance of application and
handling equipment,
• disposal of pesticides and their containers.
OSU
PSEP
Brand, Trade, or Product Names
• Usually trademarked name for Pesticide
Products
• Some Product names may be very similar but
contain a different pesticide.
OSU
PSEP
Ingredient Statement, Chemical Name,
Common Name
• The ingredient statement must list the official
chemical names and/or common names for the active
ingredients.
• The chemical name is a complex name which
identifies the chemical components and structure of
the pesticide. This name is almost always listed in
the ingredient statement on the label
• Because pesticides have complex chemical names,
many are given a shorter "common" name. Only
common names which are officially accepted by the
U. S. Environmental Protection Agency may be used
in the ingredient statement on the pesticide label.

Signal Words & Symbols
• The signal word must appear in large letters on the front panel
of the pesticide label. It immediately follows the statement,
"Keep Out of Reach of Children," which must appear on every
pesticide label. The signal word is based not on the active
ingredient alone, but on the contents of the formulated product.
It reflects the hazard of any active ingredients, carriers,
solvents, or inert ingredients. The signal word indicates the
risk of acute effects from the four routes of exposure to a
pesticide product (oral, dermal, inhalation, eye) and is based
on the one that is greatest. The signal word does not indicate
the risk of delayed effects or allergic effects.

DANGER - This word signals you
that the pesticide is highly toxic. A
taste to a teaspoonful taken by
mouth could kill an average sized
adult. Any product which is highly
toxic orally, dermally, or through
inhalation or causes severe eye and
skin burning will be labeled
"DANGER".
All pesticides which are highly
toxic orally, dermally, or through
inhalation will also carry the word
POISON printed in red and the skull
and crossbones symbol.
WARNING - This word signals
you that the product is moderately
toxic. As little as a teaspoonful to a
tablespoonful by mouth could kill
the average sized adult. Any
product which is moderately toxic
orally, dermally, or through
inhalation or causes moderate eye
and skin irritation will be labeled
WARNING.
CAUTION - This word signals you
that the product is slightly toxic.
An ounce to more than a pint taken

Directions For Use
• Instructions on how to use the pesticide are an important part
of the label for you. This is the best way you can find out the
right way to apply the product. It is illegal to use a pesticide in
any way not permitted by the labeling. A pesticide may be
used only on the plants, animals, or sites named in the
directions for use. You may not use higher dosages, higher
concentrations, or more frequent applications. You must
follow all directions for use, including directions concerning
safety, mixing, diluting, storage, and disposal. You must wear
the specified personal protective equipment even though you
may be risking only your own safety by not wearing it. The
use directions and instructions are not advice, they are

Reading the Label
• Before you buy a pesticide, read the label to determine:
whether it is the pesticide you need for the job, whether the pesticide can be
used safely under the application conditions.
• Before you mix the pesticide, read the label to determine:
what protective equipment you should use, what the pesticide can be mixed
with (compatibility), how much pesticide to use, the mixing procedure.
• Before you apply the pesticide, read the label to determine:
what safety measures you should follow, where the pesticide can be used
(livestock, crops, structures, etc.), when to apply the pesticide (including
the waiting period for crops and animals), how to apply the pesticide,
whether there are any restrictions for use of the pesticide.
• Before you store or dispose of the pesticide or pesticide container, read
the label to determine: where and how to store the pesticide, how to
decontaminate and dispose of the pesticide container, where to dispose of
surplus pesticides.

Spray Equipment Preparation
Select an operating speed that can be maintained to
suit the field surface and crop condition.
Select nozzle sizes that deliver the desired flow rate
at the selected ground speed.
Select tips that deliver the desired droplet size
range. To reduce drift to sensitive plants, apply
herbicides with low pressure (under 40 psi) and
larger droplet size. PSI is pounds per square inch as
read from a pressure gauge. Use high pressure (60
psi or more) for small drops to get penetration and
more complete coverage of crop foliage with
herbicides, insecticides and fungicides.
Check nozzles to be sure they are providing
uniform coverage. This can be done making sure
the nozzles are facing the same direction.
Remove and clean all nozzle tips and screens. Use
an old toothbrush or a wood toothpick as they will
not damage shape or size of orifice. Do not use a
pocket knife or wire on tips. Remove and clean
suction strainer screen.
OSU
Add clean water to the supply tank; start
pump and flush hoses and boom.
Reassemble all screens and tips. Make
sure that all tips are the correct size and
type for the desired spray pattern. Check
all connections for leaks. Check the
sprayer at field pressure for uniform flow
from all nozzles, using a calibrated cup or
flow meter.
Adjust the pressure relief valve to about
15 PSI above the spraying pressure.
Slowly open the agitation line control
valve until the gauge pressure drops to the
desired spraying level. All pump output
that is not discharged through the spray
nozzle recirculates through the venturi jet
agitators or the relief valve. One jet
agitator is usually sufficient for tanks up to
100-gallon capacity; use two in larger
tanks.
PSEP
Sprayer Components
• Pumps- Roller, Centrifugal, Piston
• Tanks-Size, Tank Material, Markings, and drains are tank
factors.
• Agitation-Mechanical or Hydraulic
• Hoses-Flexible, Pressure rated, proper size
• Strainers-Proper size and regular cleaning to ensure proper
flow rate.

Factors Affecting the Risk of Injury from
Contaminated Tanks
• Herbicide Mode of Action
– Certain chemicals present a greater potential than others for
crop injury.
• Insecticides
- If using repellent and non repellent insecticides tank cleaning can
become important to get full benefit of non-repellent insecticides.
• Application Method
– Post applications on foliage provide a higher risk for crop injury
than soil applications in most cases.
• Sprayer Components
– Fiberglass and Polyethylene tanks and rubber hoses require
more extensive cleaning than stainless steel.
– Screen, strainers and pumps must also be cleaned.
OSU
PSEP
Tank cleaning agents
• Commercial tank cleaners such as All Clear,
Wipeout, Protank Cleaner and Tank Cleaner
• The old standby - Ammonia
– Recommended for 2,4-d, Remedy, Reclaim, Tordon,
Banvel, Grazon P+D, Cimarron Max, and other
hormone type herbicides
– Good for loosening deposits and residues which can
form in the tank.
– Use 1 gallon of ammonia per 100 gallons of tank
capacity.
– Ammonia can corrode aluminum parts.
OSU
PSEP
Tank cleaning agents
• Chlorine bleach (1/2%)
– Can decompose residues of sulfonylurea herbicides into inactive
compounds.
– Not recommended if you are using ammonia or liquid fertilizers
containing ammonia.
– Bleach is typically less effective at loosening residue.
• Detergent
– Rate of 1 cup/20 gallons is recommended on a few herbicide
labels. (Aim, atrazine, Sencor, Poast)
• Kerosene or fuel oil
– A solvent for oil-soluble herbicides such as 2,4-d esters.
– After an oil rinse, rinse with detergent or ammonia.
OSU
PSEP
General Cleaning Guidelines
• Clean as soon as possible after use – dried material is
difficult to remove.
• Drain the tank of ALL herbicide solution. Rinse
down the inside and outside walls of the tank and
flush out the booms. Apply this rinsate to the field
originally sprayed.
• Fill the tank with water. Circulate it through the entire
spray system including bypass, pump, hoses and
boom.

General Cleaning Guidelines
• Drain the entire system completely, including the
low spots.
• Remove all strainers and nozzle screen and clean
them separately in the cleaning solution.
• Partially refill the tank and the chosen tank cleaner.
• Finish filling the spray tank to insure the solution
contacts the internal surface of the tank.
OSU
PSEP
General Cleaning Guidelines
• Circulate the solution through the entire system.
• Allow the solution to stand in the tank for the period of time recommended
on the herbicide label (overnight is desirable).
• The next day, circulate it again through the entire system, remove end caps
on the boom, and then drain completely.
• Rinse out twice with clean water, recirculating and draining each time.
Other Tips
• Use of surfactants and fertilizer additives such as 28% UAN in subsequent
tank fillings are more apt to pull the previously used herbicides out of
fiberglass/poly tanks, rubber hoses and strainers.
• Be especially thorough in your tank cleaning procedures before applying
any herbicide (i.e. glyphosate) that recommends using ammonium sulfate
in the solution.

Drift
• Spray drift is that portion of the spray material
that moves off the target area. Drift can be
either liquid or vapor. Liquid particle drift is
easier to understand as you can see swirls of
mist moved by the wind as a sprayer crosses a
field. Some herbicide vapors drift great
distances from the target area and damage
susceptible species.
OSU

OSU
Droplet Size
Wind Speed

Climatic Conditions
PSEP
Drift Control Measures
1) Select a nozzle that produces coarser (larger)
droplets
2) Use lower pressure on the sprayer and larger
nozzles when possible
3) Lower boom height
4) Spray when wind speeds are low to avoid off target
movement.
5) Spray when wind is moving away from sensitive
crops
6)Use Buffer Zones of 50 to 100 feet in width around
sensitive areas. Spray buffer area when wind
direction is away from the sensitive area.
