What is a Horn Seeder?

• A. A simple device for applying granules.
• B. A high-pressure sprayer designed for liquid pesticides.
• C. An aerial application system that uses ram-air pressure for distribution.
• D. A handheld fogging device for disinfection.

Answer: (A)

A horn seeder is a simple manual tool used to broadcast dry granules. It’s a horn-shaped container that holds granular pesticide formulations, and the operator releases the granules by tilting or shaking the device as they move along the treatment area. This method is ideal for applying granular larvicides to standing water and other mosquito larval habitats, providing an even, localized distribution with minimal drift compared to liquid spraying. It is specifically for dry formulations, unlike high-pressure sprayers (liquids), aerial ram-air systems (airborne distribution), or fogging devices (aerosols). In essence, it’s the straightforward, low-drift option for spreading granular products to target mosquito larvae.
