✔✔What are inorganic pesticides? - ✔✔They are of mineral origin and therefore do not
contain carbon.
Inorganic pesticides are used today primarily to manage plant diseases.
They may be toxic to a wide range of organisms (broad-spectrum).
✔✔Do organic pesticides contain carbon? - ✔✔Yes
✔✔Synthetic organic pesticides are... - ✔✔man-made, carbon-containing chemicals
✔✔What is a "Mode of Action"? - ✔✔A pesticide's mode of action is the method by
which it kills or adversely affects the target pest.
✔✔Protectants - ✔✔Products to prevent pest establishment.
✔✔Sterilants - ✔✔Pesticides that manage pests by rendering them incapable of normal
reproduction are known as sterilants.
✔✔Selective - ✔✔A pesticide is selective if it is effective against one type of organism
and not another.
✔✔Nonselective - ✔✔When a pesticide kills or adversely affects many organisms in a
target site, it is considered nonselective.
✔✔Broad-Spectrum - ✔✔Pesticides that control a wide range of pests are considered
broad-spectrum. They are sometimes labeled as multipurpose pesticides.
✔✔Contact - ✔✔Pesticides that kill or adversely affect pests simply by contacting them
are known as contact pesticides.
, ✔✔Systemic - ✔✔Pesticides that are absorbed by one part of the animal or plant and
distributed internally to other parts of the animal or plant are systemic pesticides.
✔✔Persistent - ✔✔Persistent pesticides remain active for a period of time after
application and give continued protection against the pest.
✔✔Nonpersistent - ✔✔Pesticides that control pests at the time of application and then
break down quickly are nonpersistent.
✔✔Active Ingredient - ✔✔The component of a pesticide that controls the target pest.
✔✔Pesticide Formulations - ✔✔Mixtures of active and inert ingredient
✔✔How can you reduce pest resistance? - ✔✔When making repeated pesticide
treatments to a system or area for the same pest, using pesticide products with different
modes of action as well as other pest control methods (such as sanitation, crop rotation,
etc.) is recommended.
✔✔Emulsifiable Concentrates (EC) - ✔✔An emulsifiable concentrate formulation usually
contains a liquid active ingredient, one or more petroleumbased solvents and an agent
that allows the formulation to be mixed with water to form an emulsion. An emulsion is
one liquid dispersed, usually as very small drops, throughout another liquid
✔✔How much active ingredient is found in a gallon of EC? - ✔✔Each gallon of EC
usually contains 25 to 75 percent (2 to 8 pounds) active ingredient. EC's are among the
most versatile formulations.
✔✔Solutions (S) - ✔✔Some pesticide active ingredients dissolve readily in a liquid
solvent, such as water or a petroleum-based solvent. When mixed with the solvent, they
form a solution that will not settle out or separate.
✔✔Flowables (F or L) - ✔✔Some active ingredients are insoluble solids. These may be
formulated as flowables in which the finely ground active ingredients are mixed with a
liquid, along with inert ingredients, to form a suspension.
✔✔Aerosols (A) - ✔✔These formulations contain one or more active ingredients and a
solvent. Most aerosols contain a low percentage of active ingredient. There are two
types of aerosol formulations — the ready-to-use type, and those made for use in
smoke or fog generators.
✔✔Formulations for smoke or fog generators - ✔✔These aerosol formulations are not
under pressure. They are used in machines that break the liquid formulation into a fine
mist or fog (aerosol) using a rapidly whirling disk or heated surface.
