In which application method is the pesticide poured around the base of a plant?

The method where the pesticide is poured around the base of a plant is known as a soil drench. This technique involves applying a pesticide solution directly to the soil, allowing it to soak into the root zone where it can be effectively absorbed by the plant's roots. This method is particularly useful for controlling soil-borne pests or diseases and promotes systemic uptake of the pesticide throughout the plant.

Soil injection, while also a technique used to apply pesticides to the soil, involves creating holes in the soil and injecting the pesticide directly into those holes, which is different from simply pouring it around the plant base. Basal spray refers to applying pesticide to the base of the plant but typically in a spray form, not as a pour. A foliar spray, on the other hand, refers to applying pesticides directly onto the leaves of the plant rather than the soil or base. Understanding each method's purpose and execution is crucial for effective pest management and ensuring the healthy growth of plants.
