Study Notes

PESTICIDE FORMULATIONS

Pest control involves understanding key concepts: pest, injury, environment, control, kill/eradication, management, IPM (Integrated Pest Management), and resistance/tolerance.

Basic Concepts

Chemical control involves using pesticides, which consist of an active ingredient (a.i.) and technical grade.
A pesticide can have multiple names: chemical name, common name, trade name/commercial/brand name, with the registered symbol (®).

PESTICIDE FORMULATIONS

Pesticides are formulated prior to use, comprising:
- Active ingredient (a.i.)
- Additives (inert ingredients) that enhance safety, effectiveness, ease of measurement, mixing, application, and handling.

Ideal Formulation

Two major advantages of an ideal formulation:
- Safe
- Effective

Manufacturing and Sales

Active ingredients are manufactured as technical grade before being formulated.
Formulations are the final products sold for use, often under a brand name.
