Facility downtime is also reduced as fumigation exposure time is typically just 16 to 24 hours.

The Formula for More Than 55 Years of Success

The active ingredient in ProFume® fumigant is sulfuryl fluoride, which has been used for more than 55 years to protect homes from hundreds of millions of dollars in damages each year. It works by disrupting the glycolosis and citric acid cycles within cells, which deprives insects of the energy needed for survival. Due to this mode of action, sulfuryl fluoride has no cross-resistance with other insecticides, including fumigants. Cross-resistance occurs when resistance to one insecticide confers resistance to another insecticide, even when the insect has not been exposed to the latter product.

The Fumigation Process

ProFume arrives at the fumigation site in cylinders, each containing 56.7 kg of fumigant as a liquid under pressure. The fumigation site is sealed and secured to prevent entry. The calculated amount of fumigant is released from outside the structure through one or more introduction hoses and immediately converts to a gas due to its high vapor pressure and low boiling point. Fans help circulate the fumigant until it reaches equilibrium. The fumigant concentration level is maintained for sufficient time to ensure efficacy against the targeted pests. When the fumigation period is complete, the fumigated area is opened for ventilation and aeration. The gas rapidly dissipates, and air is sampled within the fumigated space to ensure it is safe for reoccupancy.

Bunker Fumigation Advantages

ProFume fumigant is increasingly being relied upon to ensure grain quality from insect damage in large (300t+) bunker fumigations.

Use of ProFume can reduce fumigation times by two weeks or more in comparison with a phosphine blanket fumigation. Additional time and labour benefits are possible, as ProFume has more rapid ventilation times than phosphine and there is nothing to clean up or dispose of after the fumigation. ProFume aerates quickly to allow faster ventilation. Rapid aeration reduces the potential of transporting fumigant residues on the road or risking an export rejection due to live insects or phosphine levels above the approved limits.

ProFume also can eliminate the need for multiple fumigations with phosphine because it is proven to control phosphine-resistant insects. ProFume is vitally important to manage phosphine-resistant insects. Because it controls all life stages of phosphine-resistant insects in stored grain, many industry experts recommend use of ProFume in a rotation program at least once per year in each storage to help manage phosphine-resistant insect populations.

ProFume is proven to control all life stages and species of stored product insects. The prescribed dosage from Fumiguide® allows flexible choice of concentrations and exposure periods. In well-sealed shipping containers, silos and grain bags, exposure periods of 24 to 48 hours are possible.

Reduced Facility Downtime

A fumigation with ProFume can reduce facility downtime during the preparation stage because it is noncorrosive and sensitive equipment does not need to be removed or sealed to exclude it from the fumigated space. Facility downtime is also reduced, as fumigation exposure time is typically just 16 to 24 hours. An even shorter exposure time is possible if a higher dosage is used as calculated with proprietary Precision Fumigation tools and techniques.
