This system comprises CO.sub.2-releasing microorganisms, and also nutrients specific to these microorganisms, and this system, or the device, comprises one or more biodegradable biopolymers and allows CO.sub.2, and optionally other attractants, to be released over a period of more than 20 days. Furthermore, the present application provides for the use of such a system or such a device for the attraction of pests, more particularly of maize or potato pests, such as larvae of the Western corn rootworm or wire worm. The present application is also directed, lastly, to methods for attracting pests, more particularly pests of maize or potatoes, such as the larvae of the Western corn rootworm, or for wire worms, with the systems or devices of the invention being positioned in the immediate vicinity of the plants, but preferably not directly on the plants.

A system for exterminating insects includes a housing, a fluid-heating assembly housed within the housing that includes one or more fuel reserves, one or more burners that receive fuel from the one or more fuel reserves, and a heat exchanger defining a sinuous flow path positioned to receive heat from the one or more burners, a fluid inlet line coupled to the housing and fluidly connectable to a residential hose bib, the fluid inlet line fluidly coupled to the sinuous flow path of the heat exchanger, such that fluid is directed from the fluid inlet line directly to the sinuous flow path of the heat exchanger, and a fluid outlet line coupled to the housing and fluidly coupled to the sinuous flow path of the heat exchanger such that fluid is directed from the sinuous flow path of the heat exchanger directly through the fluid outlet line.

A method for the extermination of burrowing vermin is disclosed. The method employs a smoke generating fluid formed of castor oil or castor oil in a mix with secondary components. The fluid is heated to a smoking temperature and the smoke is mixed with a pressurized airflow to communicate the smoke to the tunnels occupied by the burrowing vermin to remove them, and to leave a residue from the smoke which exudes an order deterring the re-occupancy of the tunnels.

The present invention relates to the use of a fumigant barrier film for treating soil by fumigation, said film having, on at least one portion of the outer surface thereof or on at least one portion of the inner surface thereof or on at least one portion of the outer and inner surfaces thereof, at least one continuous self-adhesive or self-sticking or tackifying area. The present invention also relates to the method for sealing soil intended for fumigation treatment or in the process of fumigation treatment or which has been treated by fumigation, by covering said soil with a self-adhesive fumigant barrier film, as well as to a kit for fumigation treatment including at least one self-adhesive fumigant barrier film and at least one fumigant.

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.

The present invention relates to an apparatus and a method for exterminating pests by injecting high-temperature steam into the ground including sand and the like, wherein a needle rod fixing plate (20) in which a plurality of needle rods (30) is arranged and fixed at the left and right sides thereof is coupled with a lever plate (12) rotated upward and downward by an operating cylinder (10) at a backside of autonomous power equipment (2), a steam generation unit (16) is provided to generate high-temperature steam enabling insect extermination and sterilization and supply the steam to steam injection holes (36) of the needle rods (30), a steam generation unit (16) and a needle rod (30) are connected by a hose, a steam distributor (44-1, 44-2) for supplying the steam to each needle rod (30) is provided on the hose, both ends of the steam distributor (44-1, 44-2) are coupled with a cover (48) so as to be sealed, a heating wire (49) for increasing the temperature of the steam again is provided therein, the needle rods (30) are inserted and moved forward in the bowels of the earth (6) by operating the autonomous power equipment (2), and a pest extermination operation unit (4) includes a control unit (80) for controlling the continuous injection of steam into the ground (6) so as to exterminate insects and sterilize the ground by enabling the dry or wet high-temperature steam to continuously permeate into the ground.

A cross-linked, water absorbent polymer is mixed with desirable additives and coated to prevent water absorption to create a blend that is added to water injection systems for turf and soil maintenance. The coating is rinsed off the water absorbent polymer resulting in expansion of the polymer into a gel-like substance. The water absorbent polymer has the ability to retain water and nutrients in the soil preventing nutrient runoff and reducing watering frequency. Injection of the water absorbent polymer directly into soil reduces waste and reduces hazard caused by slippery material left on soil surfaces. The method and system for mixing and injection into soil is disclosed.
