What type of application equipment is likely to provide an uneven application?

Using a trigger pump sprayer on sloping ground is likely to lead to an uneven application of pesticide. This type of sprayer requires manual operation, which can be influenced by the operator's ability to control the flow and coverage of the liquid. On sloped surfaces, gravity can cause the pesticide to run or pool in certain areas rather than providing a consistent application across the treated zone. This uneven distribution can result from variations in pressure and the ability of the operator to maintain a steady application rate while navigating the slope, leading to potentially ineffective pest control in areas that receive either too much or too little pesticide.

In contrast, other types of equipment such as granular applicators on flat ground, ultra low volume sprayers, and self-propelled sprayers are designed to minimize the risks of uneven application. Granular equipment is effective on flat surfaces since it can distribute granules uniformly without the compounding difficulty of terrain. Ultra low volume sprayers are engineered for precise, low-volume applications, which helps ensure consistent coverage. Self-propelled sprayers often have advanced technology for even distribution, reducing the risk of uneven application.
