Importance of Insulation in Fumigation

In fumigations using phosphine; Keeping a certain level of concentration in the environment for certain periods is the most important rule for success. In fumigation with phosphine, the application time is more important than the concentration in terms of success; it is even known that in very high concentrations, pests do not die and enter into protective narcosis. Studies have shown that long-term fumigation at low doses should be preferred instead of short-term fumigation at high doses.

 

 

 

Fumigation with phosphine is used in cereals, legumes, dried fruits and mill fumigation in our country. However, in practice, problems are often encountered in terms of effectiveness. As a general rule in fumigation, fumigation is done in sufficiently gas-tight environments and the gas concentration should be followed during the fumigation. In developed countries, "gas permeability test" is mandatory to determine the suitability of the environment to be fumigated. If the environment meets the desired conditions as a result of this test, fumigation can be done. In our country, on the other hand, there is no regulation defining the conditions of the environment where fumigation can be made, and therefore, adverse conditions are often experienced in terms of gas permeability.

 

 

 

The general rule in fumigation is to measure the gas concentration at frequent intervals during the application, no matter which fumigant is used, and to guide the application according to the recorded gas concentrations. In our country, there is a great deficiency in measuring gas concentrations during fumigation, especially in fumigation. For this reason, fumigation is carried out within a certain dose and duration, and as a result, low-successful results are often encountered. This is the condition that triggers resistance, especially in phosphine.
