What equipment is often used for applying liquid fumigants in soil?

Using power-mulch or rotary tillers for applying liquid fumigants in soil is a common and effective practice. These types of equipment are designed to mix and incorporate fumigants directly into the soil, which is essential for ensuring that the chemicals are evenly distributed and reach the target pests or pathogens effectively. The mechanical action of tillers also helps to create a homogenous mixture within the soil, increasing the efficacy of the fumigation process.

In contrast, backhoes are generally not equipped for the precise application of liquid fumigants and are mainly used for excavation or moving soil. Spray tanks typically cater to surface applications of pesticides and may not effectively engage the soil as needed for fumigation purposes. Hand-held sprayers, while useful for small-scale applications, lack the efficiency and coverage necessary for treating larger areas or for ensuring the penetration of the fumigant into the soil. Thus, the use of power-mulch or rotary tillers is particularly suited for this type of fumigation application.
