What is the most frequent cause of applying too much or too little spray with a low pressure boom sprayer?

The most frequent cause of applying too much or too little spray with a low pressure boom sprayer is changes in speed of travel. When the speed of the sprayer changes, the amount of spray being applied per unit area can vary significantly.

If the sprayer moves faster than intended, the amount of pesticide applied over a given area decreases, potentially leading to under-application. Conversely, if the sprayer moves slower, it may apply too much pesticide over the same area, which can result in excess application.

Maintaining a consistent speed is crucial for achieving uniform spray coverage and ensuring that the correct amount of pesticide is applied, keeping both efficacy and safety in mind. Other factors can influence application rates, such as pressure, nozzle openings, and mixture consistency, but variations in speed are typically the most impactful in terms of achieving the desired application rate.
