How do granular pesticides differ from dusts?

Granular pesticides are distinct from dust formulations primarily in their ability to be activated by moisture. This characteristic is important because it means that granular pesticides release their active ingredients when they come into contact with water, either from rain or irrigation. This activation can enhance their effectiveness by facilitating the uptake of the pesticide by target pests or plants, aligning with their intended application methods, which often involve soil incorporation or placement on foliage.

Understanding this property of granulars helps clarify their suitable applications in various pest management strategies, particularly for soil-dwelling or surface-active pests. The composition of granular pesticides usually allows for a more sustained release of the active ingredient, making them apt for extended pest control.

Other choices do not accurately represent the nature of granular pesticides. For instance, the assertion that granulars are lighter and more volatile is not true, as granulars are typically heavier and designed to remain in place until activated. The claim that dusts are specifically formulated for soil application is misleading, as dust formulations are typically aimed at applications on surfaces to control pests rather than being limited to soil use. Finally, while some granular products may contain surfactants, the assertion that granulars have no surfactant content is not universally correct, as various formulations can include surfactants
