What should be done after the final spray pass using in-flight rinsing systems?

After completing the final spray pass, it is essential to rinse the spray system properly to ensure that no pesticide residues remain in the equipment. This process is crucial for several reasons. First, it helps to prevent contamination in future applications by eliminating leftover chemicals that could mix with new ones. Secondly, proper rinsing promotes environmental safety, as any residual pesticides in the system could potentially contaminate nearby water sources or harm non-target organisms when the equipment is stored or used again.

Using the in-flight rinsing systems effectively can help ensure that all parts of the spray system, including hoses, nozzles, and tanks, are thoroughly cleaned. This practice not only protects the integrity of the application equipment but also ensures compliance with safety regulations and practices.

While other options may seem relevant, rinsing correctly is a fundamental step in maintaining equipment and ensuring safety for both the applicator and the environment. This step should not be overlooked at the end of a spraying operation.
