Bacteria, Fungi (mold), Nematodes (roundworms), rodents, weeds, slugs and snails, insects,
birds, mites, and wildlife such as raccoons, moles, and deer when damaging crops.
Pesticide - Answer A pesticide is anything that is intended to prevent, destroy, repel, attract
or manage a pest.
Active Ingredient - Answer An active ingredient (a.i.) is the part of a pesticide formulation
that produces the desired effects. Pesticides contain more than one ingredient. The material in
a pesticide formulation that controls the pest is called the active ingredient. The active
ingredient controls the pest by:
- Killing the Pest
- Reducing the numbers of the pest
- Keeping the pest from returning to do damage
Formulant - Answer Any component of a pest control product that is added to the product
and that is not an active ingredient.
- Formulants are other materials added to active ingredients to make them suitable for storage,
handling or application. They are sometimes called "other ingredients".
Formulation - Answer A formulation is a mixture of active ingredients and formulants.
A formulation may consist of:
- The active ingredient that controls the target pest
- A solvent or mineral clay to dilute the active ingredient
- Surface-active ingredients, such as stickers and spreaders
- Ingredients such as stabilizers, dyes and chemicals that improve or enhance pesticidal activity.
Adjuvants - Answer An adjuvant is a substance added to a pesticide mixture to enhance the
pesticide's qualities.
Adjuvants are substances that are added a the time of application to make the product safer to
use, more effective, more convenient to handle, or easier to apply. Adjuvants are registered for
specific uses with a specific pesticide. Adjuvants work by:
- Making the spray stick to the surface of the target better
, - Improving spray droplet uniformity to give more complete coverage
- Altering the pH of the spray water
- Increasing/decreasing evaporation to improve the drying of the spray mixture.

products by their manufactures. These names appear prominently on the pesticide label. The
Product Name is sometimes also called the Trade Name
Common Name - Answer This name refers to the active ingredient. The common name
appears on the label beside or under the word " Guarantee". Because there can be more than
one active ingredient in a pesticide product, there can be more than one common name listed
on the label.
Chemical Name - Answer This refers to the name of the chemical structure of the active
ingredient. The chemical name does not usually appear on the label but will be on the Safety
Data Sheet.
Registration Number - Answer This registration number identifies a pesticide by its product,
(trade) name, name of manufacturer or registrant, type of formulation, concentration of active
ingredients and the class of pesticide.
"CIDE" - Answer Means to kill
acaricide - Answer kills spiders and mites
algicide - Answer kills algae
avicide - Answer kills birds
bactericide - Answer kills bacteria
fungicide - Answer kills fungi
