Molluscicides are commonly formulated as granules.

• A. Granules
• B. Aerosols
• C. Dusts
• D. Baits

Answer: (A)

Molluscicides are designed to be eaten by slugs and snails, so the formulation should be something that stays put on the soil surface and is easy for these pests to encounter and ingest. Granules fit that need well: they can be spread evenly around plants, land on moist soil where molluscs travel, and often include attractants to entice feeding. Once consumed, the active ingredient works through ingestion, giving effective control.

Granules also have practical advantages over other forms. They stay where you apply them, reducing drift and exposure to non-target organisms, and they release the active ingredient gradually with moisture, providing longer-lasting effect. In contrast, aerosols disperse in the air and are not well-suited to ground-dwelling molluscs; dusts can blow away and create drift or safety concerns; while baits can be used in some contexts, granules are the most common, convenient, and reliable delivery method for molluscicides in gardens and field settings.
