Pesticides are mixed with to enhance action.

• A. Buffers
• B. Adjuvants
• C. IGRs
• D. Other Pesticides

Answer: (B)

Pesticides are mixed with adjuvants to boost how well the product works by improving coverage, adhesion, and penetration. Adjuvants can reduce surface tension so spray droplets spread more evenly on leaves, help the product stick to the plant so it isn’t washed off easily, and sometimes aid entry into plant tissues or pests. This combination often leads to better pest control at lower active ingredient rates and can extend the product’s efficacy in the field. Buffers adjust pH and are used mainly to stabilize a formulation, not to enhance pest-killing action. IGRs are themselves a type of pesticide, not additives designed to boost performance. Mixing with other pesticides can occur but is about broadening control, not specifically about enhancing action through adjuvants.
