Which statement about fumigant pesticides is false?

The statement that fumigants target a wide range of pests is false. Fumigants are highly specialized pesticides formulated to act on various types of pests, including insects, diseases, and nematodes. They are effective because they penetrate materials or areas where traditional pesticide applications cannot reach, such as in soil or enclosed spaces like storage facilities.

However, while they can be effective against various pests, they also have specific target organisms and may not necessarily target all pest types across different environments. Thus, it would be inaccurate to say they target a wide range universally.

In contrast, the other statements are accurate. Fumigants are indeed utilized in both agricultural and residential settings, showcasing their versatility. They are typically applied as gases, ensuring even distribution and penetration. Lastly, fumigants typically work effectively at low concentrations due to their potent gaseous form, providing lethal effects while minimizing the amount of product needed.
