What is a key difference between soil-applied and foliar-applied pesticides?

Soil-applied pesticides are incorporated into the soil, allowing them to target pests at or near the root zone of plants. This method focuses on controlling soil-dwelling pests or diseases that affect plants through their roots. The pesticide can be taken up by the plant's root system, providing protection against soil-borne pests and diseases.

In contrast, foliar-applied pesticides are sprayed directly on the leaves and are designed to control pests and diseases that pose a threat to the plant's foliage. This distinction is crucial, as the mode of application dictates the target pests and the effectiveness of the pesticide. Understanding the difference helps in choosing the appropriate method based on the specific pest problem being addressed, ensuring better pest management and plant health.
