Produce Storage Fumigation
Proper produce storage fumigation is crucial for maintaining quality and extending shelf life. Utilizing a state-of-the-art fogging machine for fumigation offers unbeatable effectiveness in eradicating pests and pathogens that threaten produce. Our commercial fumigation equipment ensures thorough and uniform treatment, penetrating even the smallest crevices to provide complete protection.
Whether you’re a small farmer or own a large agribusiness, produce storage fumigation with our equipment means benefiting from superior technology and expert guidance. We are committed to offering reliable solutions that safeguard your produce, ensuring it reaches consumers fresh and uncontaminated.
Aerosol droplets that are produced by Dyna-Fog® units have a wide range of uses and applications on foodstuffs as well as other products such as tobacco and leather in storage. The thermal fogs create small droplets that will carry into virtually the entire airspace in a building. In addition, ULV droplets will enter airspaces without remaining in the air for an extended time period, and, with some units, the droplets can be formed in adequate numbers to create a wetting effect on a variety of surfaces.
Treatment of Empty Stores:
Comprehensive cleaning of the structure is an essential requirement for successful insect control, ensuring that layers of dust and debris do not protect insects and other vermin. After a thorough cleaning, a good extermination of exposed insects can be accomplished with a fogging ULV machine. In cases where a residual deposit is also needed, a ULV unit that delivers the correct size droplets will result in a good knockdown of insects in satisfactory numbers, as well as give a wetting effect to surfaces. A ULV unit is also ideal when the structure is fabricated of materials, which have deep cracks and crevices (such as wood or brick), where the greater wetting capability of ULV-sized droplets will result in greater infiltration.
Treatment of Bulk Stored Potatoes:
A thermal fog can be applied as a sprout suppressant of potatoes stored in boxes or in bulk. In a large bulk stack configuration, forced air is required to assist the fog through the stack. When the stack is covered with straw for frost protection, caution should be exercised in handling the unit, ensuring that the straw does not ignite.
Treatment of Bagged Produce and Processing Rooms:
Generally, only natural pyrethrins can be used to treat bagged produce and in processing rooms: in addition, a suitable formulation for either thermal fogging or ULV should be selected. Typically, only insects on the bags’ surfaces and flying insects will be controlled. Best results are usually attained with an oil-based product containing at least 3 percent pyrethrum. Alternatively, if a water-based product is utilized, some sort of carrier should be used to prevent the droplets from evaporating in the atmosphere before they reach the target surface or object.
Choosing the Right Product:
The ULV equipment is perfect for applying mold inhibitors or disinfectants into empty cold store areas before filling those areas with produce. A wide variety of thermal (hot) fogging units are available, ranging from small hand-held machines to truck-mounted units. Fogging should only be done in closed (“buttoned-down”) structures, which should not be opened for three to four hours. The Dyna-Fog® CYCLONE™ produces small droplets of the ideal size to obtain the best knockdown results of natural pyrethrum. The unit has a "reach" of about 60 feet (20m). Where regular treatments are needed, these units can be permanently installed and then timer-controlled for automatic use. The Dyna-Fog® TORNADO™, with its larger pressurized tank, produces droplets more appropriate for leaving residual droplets, as well as giving good knockdown of pests. The Dyna-Fog® MINI-PRO™ 8HP combines the advantages of the TORNADO™ and CYCLONE™ for large-scale use. Through the setting of the nozzle pressure, the choice of large or small droplets can be made. The Dyna-Fog® MINI-PRO™ 8HP is very portable when mounted on a wheel kit. The Dyna-Jet® L30 is entirely electrically powered, resulting in emission-free operation. In addition, the Dyna-Fog® NIGHTSTAR® can produce small droplets for good knockdown of pests, or larger droplets for depositing a residue for purposes of extending the control period. By programming the controls, application of the chemical formulation can be accomplished without the user being present in the building. Where there is sufficient airspace to allow the droplets to circulate, structures up to 60,000 square feet (6,000 square meters) can be treated with as little as 1-1/2 to 3 gallons (6-12 liters) of prepared chemical formulation. Treatment with ULV units should be done in closed structures; these buildings should not be used or opened for at least one to two hours after application. All structures should be adequately ventilated before allowing unprotected personnel to re-enter.
