A system for fumigating soil includes applying a fumigant film component and an underlying drip tape element to the soil to be treated. A non-tarp method can also be used through permanently buried drip tape (SDI) that is at least 8 inches deep and utilizes the soil above as the barrier to prevent the fumigant from escaping. The drip tape element is communicably connected through a throttle valve to a pressurized liquid supply of fumigant having a low boiling point and a high vapor pressure. The valve is opened to dispense vaporized fumigant into the soil and dissipation of the fumigant is controlled so that more effective soil fumigation is achieved.

A system and method for applying liquid based fertilizers and pesticides stored underground through an irrigation system includes a first irrigation system, a second irrigation system, and a storage tank partially located underground, the storage tank being in fluid connection with the second irrigation system, wherein the storage tank is configured for storing and supplying liquid fertilizer to the second irrigation system.

An improved underground fumigation method and system including a plurality of elongated pipes placed underground adjacent to a building structure, each having a series of apertures therethrough adapted to allow fumigation liquids and gases to pass along a length thereof and outwardly through the apertures. Each elongated pipe includes an external blockage preventing half-pipe attached along a substantial portion of the length of the elongated pipe and includes a series of apertures therethrough adapted to align with the apertures of the elongated pipe. A main control box is included and attached to each elongated pipe and controls the flow of fumigation liquids and gases therethrough. Furthermore, a fumigation liquid and/or gas supply tank is provided and connected to the main control box and adapted to provide fumigation liquids and/or gas to the underground fumigation system.

In a system (10) for managing a soil treatment business, an injection apparatus (12) is operable to inject soil treatment under high pressure down into soil. A control system (92) is associated with the injection apparatus (12) and is configured to collect data during operation of the injection apparatus (12). A data management system (801) is configured to receive the data collected by the injection apparatus (12) control system (92). The data management system (801) generally comprises a database for storing the collected data, with the data management system being accessible by the business for reviewing the collected data.

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.

A vacuum shut off valve mechanism for a soil fumigant applicator includes a pneumatic cylinder that is operably connected to respective fumigant dispensing tubes and shanks of the applicator through a flow divider. A pair of switch operated valves respectively control the flow of fumigant to the flow divider and operation of the pneumatic cylinder. In a first switch state a first valve is opened to deliver fumigant to the flow divider and a second valve operates the pneumatic cylinder to pressurize the flow divider and allow delivery of the fumigant to the dispensing shanks. In a second state, the first valve is closed and the second valve operates the pneumatic cylinder to draw a vacuum, which restricts dripping and leaking of residual fumigant from the tubes and dispensing shanks.

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.

The present invention relates to compositions and formulations for soil disinfection against a wide spectrum of plant pathogens and pests. More particularly, the formulation comprising (i) peracids, such as peracetic acid and an (ii) anionic surfactant, such as capryleth-9 carboxylic acid is synergistically effective in treatment of soil to control plant parasitic nematodes and soil-borne plant pathogens such as bacteria, spores and fungi.

Methods for fumigating soil include applying over fumigant-treated soil a multilayer polymeric film to form a vapor barrier between the fumigant-treated soil and the atmosphere to at least partially contain the fumigant. The multilayer film includes at least one barrier layer comprising at least one vinylidene chloride polymer and protecting layers on each side of the barrier layer. The multilayer film preferably has at least one UV protecting layer and optionally at least one reflective layer.

An injection apparatus for treating soil adjacent a structure has a handle and a manifold head attached to the handle. The manifold head has at least one inlet and at least one internal passage in fluid communication with the at least one inlet. A high pressure nozzle is in fluid communication with the at least one internal passage in the manifold head and is adapted for emitting a discharge stream of pesticide for subsurface injection of the pesticide. A low pressure nozzle is provided for applying a pesticide to the surface. The manifold head has a substantially planar contact member having a contact surface for contact with the surface beneath which the pesticide is applied. The contact member has a first opening in the contact surface in fluid communication with the high pressure nozzle and a second opening in the contact surface in fluid communication with the low pressure nozzle.
