What is the part of a pesticide formulation that is toxic to the pest called?

Explanation:
The part that provides the pesticidal effect is the active ingredient. This is the chemical or microorganism in the formulation that actually kills or controls the pest. The other components—adjuvants, carriers, and inert ingredients—support the product by improving spread, coverage, delivery, or stability, but they don’t themselves cause the pest kill. Adjuvants help with wetting and penetration, carriers carry the active ingredient in a liquid or solid form, and inert ingredients are fillers or stabilizers that aren’t pesticidal.
