What types of applications are not considered spot applications?

The correct answer highlights that greenhouse and nursery applications are typically not classified as spot applications due to the nature of how treatments are administered in these environments. In greenhouses and nurseries, the applications are often made to larger areas or entire structures to ensure uniform coverage and efficacy against pests or diseases that can spread quickly in confined spaces.

In contrast, spot applications involve targeting specific areas rather than applying a treatment across a larger field or structure. Home garden applications may include spot treatments, as gardeners often target particular plants or areas with issues. Field applications tend to cover broad areas but can still incorporate spot treatments as needed, and commercial orchard applications likewise may involve both targeted and broad treatments, depending on pest prevalence. Thus, the greenhouse and nursery context necessitates a different approach to treatment that does not align with spot application methodology.
