Embodiments of the inventive concept provide a portable organic entity termination applicator unit. The applicator unit can include an organic herbicide reservoir or can otherwise be an herbicideless applicator unit. The applicator unit can include an outer housing, a cold water supply line, an organic herbicide reservoir to hold organic herbicide, an herbicide adjustment valve for controlling a liquid mixture, a heater core to pre-heat the herbicide water liquid mixture, and a delivery pipe to expel the heated liquid. The applicator unit can include a fuel canister receptacle to receive a fuel canister. The heater core may heat the liquid using fuel stored in the fuel canister.

An herbicide spreader is capable of changing a spreading width of an herbicide. The herbicide spreader includes: a pair of upper shafts facing with a predetermined interval therebetween in a front and rear direction; a pair of side frames on left and right sides of both the upper shafts; a pair of operation handles connected to both side frames; a spray nozzle mounted to the upper shafts; wheels mounted to both side frames; and a cover sheet for covering portions of a frame main body formed with the pair of upper shafts and both side frames except the bottom. The side frames and the operation handles are rotatably connected to the upper shafts, and opening and closing angle between the left and right side frames is variable and adjusted by operating the pair of operation handles in a direction for bringing them close to or away from each other.

A blower spray device is provided having a housing which comprises an electrically driven blower and a spray nozzle, and having a liquid supply line opening into the spray nozzle. The housing has a funnel-shaped intake channel and a tubular blow-out channel, and an electrical valve is provided in the liquid supply line to activate and deactivate the liquid supply to the spray nozzle. An electronic controller having a regulating unit for the electric blower is further provided to adjust the air flow velocity.

In a method for treating soil at a work site, a first pressure application tool is connected to a base unit and moved relative thereto along a first area of the work site adjacent a structure and operated to inject soil treatment down into the soil along the first area of the work site. A second pressure application tool is interchanged with the first pressure application tool and moved relative to the base unit along a second area of the work site adjacent the structure and different from the first area of the work site. The second pressure application tool is operated to apply soil treatment to the soil along the second area of the work site.

In a method and apparatus (710) for treating soil at a work site, a high pressure application tool (712) is connected to a base unit (714) and moved relative thereto along a first area of the work site adjacent a structure (94) and operated to inject soil treatment down into the soil along the first area of the work site. A low pressure application tool (711) is interchanged with the high pressure application tool (712) and moved relative to the base unit along a second area of the work site adjacent the structure (94) and different from the first area of the work site. The low pressure application tool (711) is operated to apply soil treatment to the soil along the second area of the work site.
