Pesticide Store Area requirments
Pesticide store separately, area must be posted and locked, clean and orderly, local fire department has Safety Data Sheet, fire extinguisher, containers labeled
Service Vehicle Equipment Identification
Identified on both sides of vehicle with company two inches high. City and State where records are kept, 1 inch high
Pesticide Notification Requirements
Oral notification before agricultural application, written notification after agricultural application (label will suffice)
Endangered Species Act
Act designed to protect animal and plant species threatened or endangered
A power held by the EPA to cancel or restrict certain pesticides that may jeopardize endangered species
Clean Water Act
Protects surface water and sets limits to protect aquatic life
Regulations to Control Communicable Diseases
Communicable Disease Programs monitor diseases which are transmitted from animals to humans such as plague, tularemia, West Nile Virus
Capacity of any substance to produce injury or death
Possibility that injury will result from substance. Hazard = Toxicity x Exposure
Immediate adverse effects from exposure
Longer periods to produce signs and symptoms from exposure
True/False: The label is a legal document
The most important part of handling pesticide?
Reading the label
Safety Data Sheet (SDS)
Provides information about the chemical ingredients including emergency information
Personal Protective Equipment
True/False: The label lists the minimum PPE required?
What area gets the most pesticide exposure?
Hands and forearms
Two types of respirators
Air-supplied and air purifying
How to avoid exposure to pesticides?
Proper PPE, washing hands, keeping food, drinks and tobacco products away from pesticides
Four types of pesticide exposure?
Oral, Dermal, Inhalation, Ocular
How to open a paper container?
A sharp knife - do not tear.
Define Heat Stress
When your body is subjected to more heat than it can cope with due to age, weight, fitness level, and pre-existing conditions
Symptoms of poisoning include
Vomiting, sweating, nausea, headache
In a pesticide emergency call?
Rocky Mountain Poison and Drug Center
First Aid Treatment for Dermal Exposure?
Drench with running water for 10-15 minutes, call poison control
First Aid Treatment for Ocular Exposure?
Rinse eye for 15 minutes, call poison control
First Aid Treatment for Inhaled Exposure?
Move victim to fresh air, if unconscious, call for paramedic assistance. Call poison control
First Aid Treatment for Oral Exposure?
Read the label instructions and call poison control and get victim to the hospital. DO NOT INDUCE VOMITING unless label or medical professional directs you to
Three C's of spill management?
Control, Contain, Clean it up
True/False: We should inform the public to bring pets inside during pesticide applications
What are the best times to apply pesticides to minimize risk and exposure?
Early morning, evening, night time
Maximum amount of pesticide residue considered safe
True/False: Pesticide drift can cause residues on crops?
True/False: Good public relations are necessary when making pesticide applications?
Professional relations require?
Technical competence, professional appearance, professional attitude, ability to identify and resolve problems, educational materials for distribution.
What is considered "the environment"
Air, soil, water, plants, animals. Everything around you.
Injury to plants
How to reduce harm to natural enemies?
Use selective pesticides rather than broad spectrum pesticides
Build up of toxin from feeding on plants/animals that have been exposed to pesticides
True/False: a pond is not an example of surface water
Movement of pesticides through soil
Pesticide held strongly to soil and less likely to leach
True/False: Drift can cause illegal residues
Two types of drift?
Vapor and Particle
Factors Affecting Drift?
Droplet size, Pesticide Formulation, Application Equipment, Weather Conditions, Atmospheric Conditions
How to reduce drift?
Reduce sprayer pressure, Drift reducing nozzles, Spray discs with larger openings, Adjuvants, little to no wind, Calibrated equipment
Examples of drift hazards?
Illegal residues, bee kills, water contamination
Negative interaction between host and a pathogen
An animal, capable of transmitting a disease causing agent or parasite from one host to another. Example: Mosquito transmitting West Nile to a person.
A disease-causing organism
The living plant or animal a pest depends on for survival. Any plant or animal which another lives for nourishment.
Vector Borne Disease
Illness caused by a pathogen that is transmitted by an insect or tick from an infected individual to a susceptible individual
When a vector transports an organism such as bacteria on its feet, body hairs, or other body surfaces to the host.
Disease-causing pathogen that moves from one host to another host. Ticks and insects are important vectors of biological transmission.
When a pathogen develops from one life cycle to another.
When a host species harbors a disease causing pathogen without necessarily showing symptoms of the disease.
Some vectors pass the disease to their offspring through eggs.
Invertebrate animals, mosquitoes and ticks are the most notable. Exoskeleton, cold blooded, appendages that are jointed, segmented body.
Complete metamorphosis (four stages)
Egg, larba, pupa, and adult
Spiders, mites, ticks. Eight legs, usually two body regions, the head and cephalothorax
Malaria, dengue, yellow fever, encephalitis
Inflammation of the brain, possibly spinal cord. St Louis Encephalitis and Western Equine Encephalitis both examples caused by infected mosquitoes
West Nile Virus
Usually caused by a bite from an infected mosquito. Mosquito becomes infected when they feed on infected birds. Bird would be the reservoir host, the mosquito the vector, the human the dead end host of the pathogen.
Typhoid Fever, Myiasis
Flea Developmental Stages
Egg, Larvae, Pupae, Adults
Integrated Pest Management
What is IPM?
Combination of mechanical, biological, environmental, and chemical control methods.
Six steps successful public health pest control
3. Select best control strategy
4. Implement control strategy
5. Evaluate control - Eradication is not generally possible
6. Educate customer
Surveillance is the detection of pests, species involved, their population, and location
Only kill parts of the organism they contact
Move (translocate) from the site of application to another site where they become effective
Contact vs stomach poison
One kills on contact, on kills when consumed.
