What is a major disadvantage of using a high-pressure sprayer?

Using a high-pressure sprayer typically leads to an increased risk of overspray because the force at which the solution is expelled can create a wider spray pattern. This means that while the equipment can effectively reach tall or distant areas, it can also unintentionally apply pesticide or other chemicals to areas that are not intended for treatment, potentially affecting non-target plants, animals, or water sources nearby.

The nature of high pressure can make it challenging to control the precise landing of the sprayed material, contributing to drift and overspray. Therefore, applicators must be mindful of environmental factors, such as wind, that can exacerbate this issue, as well as adjust their techniques to minimize the risk of overspray when using high-pressure systems.

The other options, while valid concerns in different contexts, do not directly relate to the typical disadvantages associated with high-pressure sprayers. For instance, maneuverability or penetration into foliage could be influenced by various factors, but the primary concern with high-pressure systems revolves around the potential for overspray, making it a major disadvantage in pest control applications.
