What is one of the formulations that soil fumigants may take?

1. Liquids

2. Granules

3. Compressed gases

4. Tablets

The correct answer is: Granules

Soil fumigants can be formulated in various ways to enhance their application and effectiveness, with granules being one of these common formulations. Granular formulations are solid particles that can be easily spread across the soil surface or incorporated into the soil. This particular form allows for controlled release and interaction with the soil, aiding in the effective fumigation of soil-borne pests, pathogens, and weed seeds. Granules also provide several advantages, such as reducing the risk of leaching and the potential for immediate volatilization compared to liquid applications. This enables the active ingredients to remain in the soil longer, allowing for enhanced efficacy and a more prolonged control of pests and diseases. The convenience of application and reduced risk of drift during application makes granules a preferred choice for many fumigation practices. Other formulations like liquids and compressed gases may also be used in fumigation, but granules specific to soil fumigants offer unique benefits suited to soil applications.
