What is the term for placing pesticide directly on or in the soil?

The term for placing pesticide directly on or in the soil is "soil application." This method involves applying herbicides or other pesticides directly to the soil where they can interact with the root systems of plants or penetrate the soil profile to control pests or weeds effectively. Soil application is particularly important for targeting specific pest issues at the root level and can improve the efficacy of the chemical in managing soil-borne pests or pre-emergent weed control.

In contrast, foliar application refers to the application of pesticides directly onto the leaves of plants, targeting above-ground pests. Space treatment typically involves applying pesticides in a targeted manner to control pests in a specific area rather than directly incorporating them into the soil. Tree injection is a technique used to deliver pesticides directly into the vascular system of a tree to manage diseases and pests that affect trees, rather than applying them to the soil. Understanding these distinctions helps in selecting the appropriate application method for pest management strategies.
