What can cause uneven pesticide application in the field?

Uneven pesticide application can occur due to various factors, and all mentioned elements contribute to this problem. The phrase 'all of the above' rightly acknowledges that multiple conditions can lead to inconsistencies in how pesticides are applied across a field.

For instance, variable distance of application affects the amount of pesticide delivered to different areas. If the equipment is not calibrated properly or if the nozzle is malfunctioning, some areas may receive more product than others. This variability can lead to either under-application, which may result in insufficient pest control, or over-application, which could cause harm to the crops and the environment.

Inconsistent speed of operation is another critical factor; if an applicator changes speed during application, the flow rate of the pesticide can be affected. For example, moving too quickly might lead to a reduced amount of pesticide being applied, resulting in inadequate coverage, while moving too slowly might cause over-application in certain areas.

Humidity variations can also play a role in pesticide application effectiveness, particularly when it comes to evaporation rates. If humidity levels fluctuate significantly during application, it can impact how quickly the pesticide dries and adheres to the plant surfaces, leading to variations in efficacy across the field.

Combining all these aspects, it is clear that various
