Cone nozzles can penetrate dense foliage but are not ideal for mounting on a boom. This statement describes which nozzle use?

• A. Cone nozzles can penetrate dense foliage
• B. Flat-fan nozzles for dense foliage
• C. Hollow-cone nozzles for open crops
• D. Full-cone nozzles for wide-area coverage

Answer: (A)

The main idea here is choosing a nozzle pattern that can get spray to the interior of a dense canopy. Cone nozzles produce a compact, circular spray with enough momentum to push spray through thick foliage, allowing the chemical to reach lower leaves and inner parts of the plant. That penetrating capability is what the statement highlights. However, when you’re mounting nozzles on a boom for wide-area coverage, cone patterns aren’t ideal because they don’t spread as uniformly across a wide swath as flat-fan patterns do, which is why this use is described as not ideal for boom mounting. The other options describe patterns better suited to different conditions (flat-fan for even wide coverage, hollow-cone or full-cone for other canopy or drift considerations) and don’t emphasize penetration into dense foliage.
