What is the difference between a ready-to-use product and a concentrate?

• A. RTU contains measured concentrations for direct use; concentrates require dilution before use.
• B. RTU and concentrate are the same.
• C. RTU is always stronger than concentrate.
• D. Concentrates are safer to handle than RTU.

Answer: (A)

Understanding ready-to-use versus concentrate comes down to how much preparation is needed before applying a pesticide. A ready-to-use product is packaged at the application strength—no mixing or measuring required—so you can spray or apply it directly according to the label. A concentrate, however, must be mixed with water (or another carrier) to reach the recommended strength before use. This means you need to measure precisely and follow the label’s dilution instructions to hit the right rate.

This distinction matters for accuracy, safety, and cost. Concentrates give you flexibility to adjust strength for different jobs, but mis-diluting can lead to ineffective control or damage to plants, pests, or surfaces. RTUs reduce the chance of dilution errors but are typically more expensive per use and don’t allow changing the strength as easily. It’s not true that RTU is always stronger, nor that concentrates are inherently safer to handle; concentrated products are often more hazardous in their undiluted form and require careful handling.
