Which of the following is NOT a characteristic of soil fumigants?

Soil fumigants are substances used to control pests, diseases, and weeds in the soil, and they possess specific characteristics that make them effective for these purposes. One key characteristic is high volatility, which allows the fumigant to evaporate and penetrate the soil to reach targeted pests. Strong odor is another distinctive feature, as many soil fumigants have a noticeable smell due to their chemical composition.

Additionally, soil fumigants carry a risk of potential environmental contamination because they can move beyond the treated area and affect surrounding environments, making it essential to follow regulations and application guidelines carefully.

Stability at room temperature, in contrast, is not a typical characteristic of soil fumigants. Many fumigants require certain conditions to remain effective and can deteriorate or break down when not handled properly. Hence, it's important to recognize that stability at room temperature doesn't align with the functional characteristics of most fumigants. Understanding these properties is crucial for proper application and environmental safety.
