The present disclosure relates to a barrier paper comprising a paper coated with polyvinyl alcohol composition, and a method for reducing diffusion of soil fumigant using the same.

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.

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.

Disclosed are the system and method for the process of fumigation. The fumigation system injection cart allows a user to fumigate item(s) that are placed in a poly bag or container. The ambient air from the poly bag or container is sucked out through the vacuum/fumigant outlet line. A desired negative pressure is created in the poly bag or container. A gaseous fumigant is introduced into the poly bag or container through the vacuum/fumigant outlet line. A pressure gauge is configured to monitor the pressure level in the poly bag or container. A fumigant cylinder provides a gaseous fumigant supply through a fumigant tank connector and intake line. A fumigant shutoff valve allows a user to control the flow of the gaseous fumigant. A wheeled hand truck handles allow the user to mobilize the fumigation system injection cart to an application site.

Devices and methods for the control of pests, including plant pests, using the vapors of a plant health, pesticidal and/or pest control composition are disclosed. Compositions, devices and methods for the selective control of plant or other pests while not harming one or more beneficial insects are also disclosed. In some embodiments, the pests are include bugs, fleas, lice, ticks, plant pathogenic insects, acari, or the like. In some embodiments, the pests are varroa mites and the beneficial insects are honey bees.

Devices and methods for the control of pests using the vapors of a pesticidal composition. Compostions, devices and methods for the selective control of pests while not harming one or more beneficial insects are also disclosed. In some embodiments, the pests are bed bugs, fleas, lice, ticks, or the like. In some embodiments, the pests are varroa mites and the beneficial insects are honey bees.

A lightweight barrier insert door is attached to an enclosure, such as a shipping container that holds a product to be fumigated, such as during transport of the product to a new location. The barrier insert door fits within the doorway of the container to provide a sealed barrier to mitigate leakage of a fumigant from the interior of the container. The barrier also includes air intake ports to maintain the structural integrity of the container and to provide ambient air to the interior. Additional ports allow for connection for fumigant entry, monitoring, and/or an exhaust hose to be connected to or through the barrier for the fumigation process. The barrier can be height adjustable to account for shipping containers of various sizes and can be connected with fumigant exhaust and release systems for the safe release thereof.

Tarpless fumigation and powered aeration of containerized cargo within a shipping container are disclosed. A portable fumigation containment door is installed in covering relation with main rear opening of a standard cargo container. The door is adapted with a fumigant diffuser for dispersing fumigant within the container. A recirculating fan disperses and circulates fumigant within the shipping container. Powered aeration is used to aerate the container through ports in the containment door by drawing fumigant laden air from the container while drawing in ambient air, while the container refrigeration unit is used to maintain a desired temperature.
