What is the mechanism of control of fumigants?
As far as is known at present, fumigants enter the insect mainly by way of the respiratory system. The entrance to this system in larvae, pupae and adults is through the spiracles, which are situated on the lateral surfaces of the body. The opening and closing of the spiracles are under muscular control.
What are two properties of fumigants that makes it a desirable pesticide to use?
An ideal fumigant should: (1) have a low cost per effective fumigation; (2) be highly and acutely toxic to all stages of the target pest, but not unduly hazardous to man and his domestic animals; (3) be highly volatile, with a good ability to penetrate, but not be excessively sorbed on and in the commodity, its …
What is fumigant action?
Fumigation is a method of pest control or the removal of harmful micro-organisms by completely filling an area with gaseous pesticides—or fumigants—to suffocate or poison the pests within.
What is agricultural fumigants?
Agricultural fumigants help improve crop quality by preventing crop losses due to pest attacks. Hence, the global focus on increasing the quantity and quality of agricultural output is expected to increase the demand for agricultural fumigants.
How do fumigants act on stored grain?
Fumigation is a treatment that rids stored grain of insects by means of a poisonous gas called a fumigant. This substance, produced and concentrated as a gas, is lethal for specific living species.

Preparation prior Fumigation
- First, the area to be fumigated is usually covered to create a sealed environment next the fumigant is released into the space to be fumigated.
- Then space is held for a set period while the fumigant gas percolates through space and acts on and kills any infestation in the product.

- Liquid Fumigation. Liquid fumigation employs liquid fumigants for mold, pests and insects.
What is CT in fumigation?
The minimum concentration would be expected to be at the end of the fumigation under. normal circumstances, so this parameter is given as a “Minimum final concentration”. The. extent of exposure to the gas is described as “concentration over time” or CT.
