What does soil injection refer to in pesticide application?

Soil injection refers to the method of applying pesticides directly beneath the soil surface through specialized equipment that injects the pesticide under pressure. This technique targets pests that are located within the soil or those that are not easily reached by surface applications, allowing for more effective pest control. By delivering the pesticide deeper into the soil, it can quickly reach root systems or pest habitats, which may be crucial for treating certain soil-borne pests or diseases.

This method is particularly beneficial in treating issues like nematodes or certain fungal pathogens since it places the pesticide exactly where it needs to be for maximum efficacy. Additionally, soil injection minimizes the environmental impact by reducing drift and runoff, as the chemicals are applied below the surface rather than exposed to the elements.
