What is one method to determine the effective swath width when using spreaders equipped with handheld guns?

Determining the effective swath width when using spreaders equipped with handheld guns can be efficiently achieved by operating the spreader in a stationary position. When the spreader is stationary, it allows the operator to evaluate how widely the material is distributed without the complications that come from movement. This method gives precise visibility of the spread pattern, enabling accurate measurements of the width over which the pesticide is applied.

Using a stationary approach allows for the assessment of distribution uniformity and helps in identifying any variances in application rates across the width of the spread pattern. This is essential for achieving effective coverage, which is crucial for the success of aquatic weed control. Measurements taken while the spreader is stationary ensure that the swath width can be accurately identified and adjusted if necessary for improved application efficiency.

Other methods may not provide the same level of clarity or accuracy when trying to calculate the effective swath width. For instance, adjusting the spreader gate to the highest setting does not necessarily relate to measuring swath width, and measuring with an electronic device could be impractical and may not reflect the actual dispersion pattern in a field scenario. Similarly, using a control sample weight focuses more on application rates rather than the measurement of the effective swath width itself.
