Define IPM
Integrated Pest Management:
Integrated pest management (IPM) is an ecosystembased strategy that focuses on long-term prevention of
pests or their damage through a combination of
techniques such as biological control, habitat
manipulation, modification of cultural practices, and use
of resistant varieties. Pesticides are used only after
monitoring indicates they are needed according to
established guidelines, and treatments are made with the
goal of removing only the target organism. Pest control
materials are selected and applied in a manner that
minimizes risks to human health, beneficial and nontarget
organisms, and the environment.

Integrated Pest Management

IPM does:
– Define the steps to solving pest problems with
the least risk

IPM does not:
– Set risk reduction goals and measure progress
– Communicate pesticide hazard or stewardship
to public

IPM is Process based

PHAER is Results based

PHAER Zone Goal
ELIMINATE
EXPOSURE to
HAZARDOUS
PESTICIDES
– Human and environmental exposure

What Is Risk?
(low)
Exposure
(high)
Risk = Exposure X Hazard
(Low)
Hazard
(High)
Children and Pesticides
Exposure to herbicides (weed killers) linked
to a 459% increase in childhood asthma.
 Exposure to lawn and garden pesticides
associated with an approximate 40%
increased risk in developing cancer


Exposure to pesticides demonstrate
– an inhibited ability to learn
– decreased stamina
– problems with gross and fine eye-hand
coordination and 30-minute memory
– reduced thyroid hormone levels
10
Children’s Safety, Health & Wellness
 Asthma,
bronchitis, autism, cancers
are increasing
 Asthma
alone accounts for 14 million
lost school days annually.
 An
estimated $3.2 billion is spent
every year to treat asthma in children
under 18 years old.
11
Pesticide
 “Any
substance, or mixture of
substances, used for defoliating
plants, regulating plant growth,
or for preventing, destroying,
repelling, or mitigating any pest,
which may be detrimental to
vegetation, humans, or animals.”

Zones
•Areas of greatest sensitivity
•Managed with Green Materials


HUMAN HAZARD: CHRONIC

– Cancer (known, likely, probable, possible)
– Endocrine disruptors
– Reproductive toxicants

YELLOW
Zones
• Limited exposure
•If you can’t do it all now…
Transition speed based on
resources, standards
19
Prioritize Limited Resources
from
YELLOW
to
GREEN
No Exposure to
Hazardous Pesticides
20
PHAER System DOES NOT:
 Limit
 Allow
your materials list
more pesticides
 Eliminate
 Require
process
pesticides
the IPM decision-making
21
PHAER system DOES:
• Highest Standard of Safety
in Areas of Greatest Need
• Prioritize Limited Resources
• Incremental/ Measurable /Accountable
• Pesticide Use Communication Tool/
Signage for Public
• Public Education through Demonstration
• Clearly Demonstrates Good Stewardship
22
Process – PHAER Zones

Map all sites
– Areas of highest sensitivity
– Areas where yellow / red pesticides used
– Habitat modifications to eliminate the
need for pesticides


Ventura Unified School District:
Challenges

Campuses built in era of pesticides
as management
– Fencelines in turf
– Turf and landscape beds
