The present invention relates to a photocatalytic film including at least one polymer layer (1) including at least one photocatalyst, said layer being pervious to both the vapors of at least one fumigating compound and ultraviolet radiation capable of activating the photocatalyst. The present invention also relates to a method for treatment by fumigation using said photocatalytic film and at least one fumigant.

The present application is directed to a system and device for attraction of pests. 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.

Apparatus (10) or injecting soil treatment into soil includes a handle (17) and a manifold head (16) carried by the handle (17) for delivering soil treatment into soil. The manifold head (16) has a first set of high pressure nozzles (38) each configured to deliver a first volume of soil treatment into the soil at an operating pressure over an injection period and a second set of high pressure nozzles (102) each configured to deliver a second volume of soil treatment into the soil at the operating pressure over the injection period. The second volume of soil treatment is greater than the first volume of soil treatment.

The present invention relates to a method for protecting the lower regions of and structure of a building (10) from damage or degradation by termites. The method comprises the steps of creating a region in the ground below the building having properties hostile to termites whereby to discourage them from approaching the vicinity of the building. In one embodiment means for creating a hostile region in the ground below the building are provided by a pump (12) which creates a superatmoshpheric pressure field (40) in this region. Treatment agents (31) such as ozone may be delivered to the ground region in order to provide a hostile effect to the termites by affecting their pheromone chemistry and/or their reproductive or communicative behavior. A secondary function of the present invention relates to the creation of a forced ventilation (46) of the habitable region (18) within which the apparatus of the present invention resides.

A ground penetrating rig that can be coupled to machinery (e.g., a skid steer, or the like). The ground penetrating rig may have one or more mast assemblies, each having one or more rods. The mast assemblies may be located in parallel and/or in series with each other. Each of the rods of the mast assemblies may be moveable in unison or independently. However, in some embodiments the rods may be moveable in unison until at least one rod is impeded by an obstruction, and as such, the movement of an impeded rod may be restricted while allowing continued movement other rods. One or more of the mast assemblies may be able to be adjusted in order to reduce the envelope of the rig for improved transportation. Multiple ground penetrating rigs may be operatively coupled to the machinery (e.g., front and rear) to improve ground treatment efficiency.

An aperture assembly for use with a subsurface ejection vessel includes an electromagnet, a first dynamic aperture, a second dynamic aperture, a hollow shaft injection drill bit, a third dynamic aperture, collar perforations, and closed window apertures. The electromagnet actuates a closing of the first dynamic aperture. The electromagnet actuates an opening of the second dynamic aperture. The third dynamic aperture dynamically opens when triggered by a first pre-determined depth achievement counting by the encoder of the lead screw or distance traveled by a platform (505A) triggered by the limit switch that are communicated to the AI robot, the computer, and the PLC. The third dynamic aperture dynamically opens when the camera lens has a second pre-determined depth penetration of the hollow shaft injection drill bit and that the limit switch information is communicated to the computer, or the PLC.
