What is a true statement regarding measuring and transferring pesticides?

1. Plastic measuring utensils are preferred

2. Most dusts and powders are measured by weight

3. After adding the pesticide, rinsing the container is unnecessary

4. Rinse the measuring container and pour the rinse solution into the tank

The correct answer is: Rinse the measuring container and pour the rinse solution into the tank

Rinsing the measuring container and pouring the rinse solution into the tank is a best practice when handling pesticides. This process ensures that any residual pesticide left in the measuring container is effectively transferred into the application tank, minimizing waste and ensuring an accurate dosage of the pesticide. It's crucial to follow this step as part of good pesticide handling practices to reduce environmental contamination and promote effectiveness of the pesticide application. In contrast, other choices do not highlight this important aspect. Plastic measuring utensils may be suitable in some cases, but they are not necessarily preferred over other materials, as different types of pesticides can react differently with varying materials. Measuring most dusts and powders by weight is common, however, this statement does not encompass the broader practices of pesticides handling and measurement. Lastly, stating that rinsing the container is unnecessary goes against standard guidelines which emphasize the importance of rinsing to ensure no pesticide residue remains that could lead to improper dosing or environmental hazards.
