What is the effect of higher boom heights on the spray pattern?

Higher boom heights can significantly affect the spray pattern by increasing drift potential. When the boom is elevated, the distance between the nozzle and the target surface (such as crops or soil) is greater. This leads to droplets spending more time in the air before they reach the ground, which can allow wind to carry them further away from the intended target area. As a result, smaller droplets become more susceptible to drifting, which can lead to unintended areas being treated or contamination of non-target sites.

The relationship between height and drift is important for applicators to consider because managing drift is crucial for effective pest management and protecting the environment. Ensuring the boom is at an appropriate height can reduce the risk of drift while also ensuring the product is delivered efficiently to where it's needed. Adjustments to application techniques, such as lowering boom heights, can help maintain effective spray patterns while minimizing drift.
