Most pesticide formulations do not contain adjuvants so they must be added by the applicator.

• A. True
• B. False
• C. Sometimes
• D. Not applicable

Answer: (B)

Adjuvants are additives that improve how a pesticide works—things like making droplets spread, stick to leaves, or penetrate waxy surfaces. They can be built into the product by the manufacturer or added separately in the spray tank. Because many formulations already include adjuvants, and label directions may require or prohibit certain adjuvants, it isn’t accurate to say most pesticide formulations lack adjuvants and must have them added by the applicator. Always check the product label to see whether an adjuvant is included or recommended and follow those instructions. Some products come with built-in adjuvants, while others require you to add them for optimal performance.
