Chapter 3 Flashcards
Where do pesticides come from?
From our physical environment and living organisms or have made them ourselves
What is an example of a pesticide from our physical environment?
Minerals diatomaceous earth causes insects to dehydrate
What is an example of a pesticide from plants? Insects? Microrganisms?
Plants: Pyrethrum
Hormones: disrupt life cycle
Phermones: Attract insects
Bt: naturally occurring bacteria that disrupts larvae feeding in mosquito, caterpillar etc.
Target Pest: Antifouling Paints
Algae and mollusks on submerged surfaces
Target Pest: Avicides
Birds
Target Pest: Bactericides

Insects, Birds, Mammals
Target Pest: Rodenticides
Rats and Mice
Target Pest: Wood Preservative
fungi, bacteria, and insects that feed on wood
Target Pest: Defoliants
Plants (by causing leaves to drop)
Target Pest: Desiccants
Plants (by cause them to dry up)
Target Pest: Growth Regulators
Insects and plants by altering growth development
How can pesticides used against the same group differ from each other?
Different products will have different attributes that will make them more effective than others in certain situations
Mode of Action
the way a pesticide acts on a pest
Residual Insecticide
Provides control for hours, days, weeks. or even longer after application. (when insect is not present)
Nonresidual Insecticide
Effective only at the time of application or for a short time afterward (when insect is present)
Contact Insecticide
Kills insects that come into contact with it
Stomach Position
Effective when an insect swallows it
Systemic Insectice
Special stomach poison that spread that through a treated plant or animal. Insect is killed when it feeds of any part of the plant or animal
Contact Herbicide
Kills plant tissue in the immediate vicinity of where it was absorbed into the top growth to which it is applied
Systemic Herbicide
Kills established perennials because it is absorbed at the point of contact and then moves throughout the entire plant so it reaches and kills underground structures
Selective (narrow spectrum) insecticide
kill some plants but causes little or no injury to others
Non selective insecticide
kills any plant they contacts
Protectant Fungicide
Prevent fungi from infecting a plant by inhibiting fungal growth. Must be applied before the disease starts
Systemic (eradicant) Fungicide
enter and move inside a plant to control existing infections
Acute Rodenticide
will kill a rat or mouse in a single feeding
Multidose anticoagulant rodenticide
Rodent has to eat it multiple times to be killed
Pesticide Impregnated Materials
Pesticides are incorporated into or onto other products either to protect those products or to make the pesticide more effective or easier to apply
Examples or Pesticide Impregnated Materials
Treated seeds with fungicide
Weed n feed lawn care products with herbicide
Livestock Ear Tags with insecticide
Treated Lumber with wood preservative
Where can you find the type of pesticide on the product label
The type of pesticide will be displayed on the product label near the product name. If it isn’t it will be listed under the general information section
