What is NOT one of the 5 basic concepts of drift management?

The concept of managing drift in pesticide application is crucial for ensuring that products reach their intended targets without impacting non-target areas. The correct answer highlights an action that does not align with common drift management practices.

Increasing the boom height can lead to increased drift potential, as it allows the spray to be more easily carried away by wind. The other options focus on reducing the risk of drift through practices that involve controlling environmental conditions, modifying the formulation of the spray, or optimizing the application technique. Spray when wind speeds are low minimizes the chance of particles being carried off by strong winds. Adding a drift reduction agent helps to modify the physical properties of the spray, making it less likely to drift away. Using the lowest nozzle-recommended spray pressure consistent with coverage minimizes the formation of small droplets that are susceptible to air movement.

Therefore, when managing drift, it is imperative to keep the boom height lower to maintain better control over the spray and reduce drift, making the option to increase boom height a poor choice in this context.
