What type of pests are primarily targeted by deeper soil treatments?

Deeper soil treatments are specifically designed to target pests that inhabit the lower soil strata. This includes pests such as certain soil-dwelling insects and larvae that thrive beneath the surface where they may be protected from surface insecticides. These deeper treatments not only ensure the effective management of these pests but also help in enhancing soil health and preventing future infestations by eliminating the pest lifecycle stages that are hidden from above-ground treatment methods.

In contrast, surface-dwelling pests primarily inhabit the upper layers of soil or leaf surfaces, making them less accessible to deeper soil treatments. Root-dwelling pests are closely associated with the root systems of plants and may benefit from systemic treatment methods rather than deeper soil applications. Fungal pests typically require treatment strategies focused on the plant surfaces or through fungicides and are not targeted by soil depth treatments in the same way as insect pests. Thus, the emphasis on deeper soil treatments aligns specifically with the need to control pests that reside at those depths in the soil profile.
