Which statement about measuring and/or transferring pesticides is true?

• A. Rinse into tank; use the measuring container to pour the rinsed solution into the tank.
• B. Metal measuring utensils are recommended over plastic.
• C. Most dusts, powders, and dry formulations are measured by volume.
• D. Transfer should be done by pouring into the tank without rinsing.

Answer: (A)

The main idea is to ensure complete transfer of the product and minimize exposure by rinsing the measuring container into the spray tank and then using that same container to transfer the rinsate. This practice recovers every bit of product and reduces the chance of spills or residue left on equipment. Many dry formulations are meant to be weighed rather than measured by volume, so relying on volume measurements alone can introduce dosing errors. Transferring by pouring without rinsing leaves product in the container and increases the risk of under- or over-dosing and operator exposure. Metal measuring utensils are not preferred because some pesticides can corrode or react with metal; plastic or other compatible materials are recommended for measuring.
