What is NOT a factor that determines the choice of tank material for herbicide application?

The choice of tank material for herbicide application is influenced by several important factors, such as resistance to chemicals, cost, and weight. Resistance to chemicals is critical because herbicides can be corrosive; thus, the tank must be durable and able to withstand the specific chemicals being used without degrading over time. Cost also plays a significant role in decision-making, as budget constraints can limit the selection of materials available for tank construction. Additionally, the weight of the tank is a practical consideration, as it affects mobility and ease of handling when transporting and applying herbicides.

Color, however, is not a critical factor when determining tank material for herbicide application. While the color of a tank may influence heat absorption and aesthetics, it does not have a direct impact on the functionality, safety, or compatibility of the tank with herbicides. Therefore, it is not considered an essential criterion when selecting materials for herbicide tanks.
