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.

A method for pest control in a confined space using flue gas from a biomass power plant. The method includes: treating flue gas from a biomass power plant to yield treated flue gas having a volume concentration of carbon dioxide exceeding 85 volume %, and conducting pest control in a confined space according to the following steps: continuously aerating the confined space with the treated flue gas during a fallow period to allow a gas pressure in the confined space to reach between 0.110 and 0.140 megapascal of absolute pressure and the volume concentration of carbon dioxide in the confined space to reach between 50 and 90 volume %.

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 improved thermal fogging device includes an extended heat transfer surface located within the aerosolization chamber that increases the mixing of the liquid chemical particles and the hot gases in the aerosol to improve aerosolization. The extended heat transfer surface also helps to increase the heat transfer to the forming aerosol in the aerosolization chamber.

A grain pest control apparatus includes an input unit adapted to accept input of grain; a heating unit adapted to heat the grain supplied from the input unit; and a removal unit adapted to remove heat from the grain heated by the heating unit, wherein the removal unit includes a cylindrical body provided with an air passage hole in a wall surface and adapted to receive the heated grain and a heat collecting chamber installed by surrounding the cylindrical body and connected to an exhaust channel, and removes heat from the heated grain by causing air supplied into the cylindrical body to pass through the air passage hole and escape via the heat collecting chamber.

The disclosure relates to devices and methods for ventilating enclosed area such as shipping containers or structures erected to temporarily contain cargo items. A central element in such devices and methods is a ventilation stack assembly in which a vertically-oriented stack having an outlet is connected at its other end to a pipe leading to an inlet. A first housing having the dimensions (and preferably the fittings) of a standard shipping container is rigidly connected to the stack and pipes, and the assembly can be physically manipulated as if it were a standard shipping container. Gas (e.g., fumigant) provided to the pipe inlet passes through the pipe and into and through the stack, exiting at the outlet, which can be situated at an altitude whereat gas discharged therefrom is dispersed into the atmosphere at a location and concentration at which displeasure or hazard to humans can be reduced.

A multipurpose machine for cultivating trees, comprising an inverted U-shape structure that enables the machine to pass over existing trees or fruit trees to carry out pruning, disinfection or fruit picking tasks, provided at the bottom with wheels, driven by at least one motor that autonomously facilitates the movement thereof, and respective upper frames that telescopically couple to each other, being driven by means of respective cylinders to move the portion of the structure on the right with respect to the one on the left in order to vary the width of the machine. Likewise, the machine has the ability to raise or lower the upper structure of the same to adapt it to the height of the trees to be cultivated.

Many import and export regulations require fumigation of goods, such as products or commodities, to ensure that non-native pests are not introduced. The fumigating process can involve placing the goods in a sealed containment system, and introducing the sealed good to a fumigant, such as methyl bromide gas, for a predetermined amount of time. After fumigation, regulations may require how to dispense the fumigant. The fumigant can be exhausted through fans, baffles, dampers, filters, and a chimney, as part of an emission system, in a controlled manner. The controlled manner can include combining the fumigant with ambient air and releasing or exhausting the combination over an amount of time, which mitigates pollution by the fumigant. The time-period is not specific, and instead is the time needed to meet regulatory requirements.
