Which statement about measuring and transferring pesticides is true?

The statement about rinsing the measuring container and pouring the rinse solution into the tank is true and reflects proper pesticide handling practices. This procedure is important because it ensures that any residual pesticide clinging to the container is not wasted and is utilized effectively within the spray tank. Rinsing helps to minimize environmental contamination, reduces the risk of leftover pesticide affecting future applications, and follows the principle of responsible pesticide management. By incorporating the rinse solution into the tank, applicators also maintain the correct concentration of the pesticide formulation intended for the application.

Safe and effective pesticide management includes understanding the significance of reducing waste and potential contamination, which is why this practice is endorsed in pest management protocols.

In contrast, using metal measuring utensils over plastic may not always be preferable due to compatibility issues with certain pesticides that can react with metal. The method of measuring dry formulations typically relies on weight rather than volume for accuracy, and keeping the pesticide container above face level could pose unnecessary risks during handling, as spills could reach critical areas if an accident occurs.
