Multiple Choice

Cone nozzles are used to apply insecticides or fungicides in situations where what is required?

Explanation:
Cone nozzles are chosen when the spray goal is to coat the entire surface of the leaves. Their full-cone pattern produces a dense, circular spray that blankets the leaf blades, depositing droplets evenly across the foliage. For insecticides and fungicides that must contact pests on or within leaf tissue, complete leaf surface coverage ensures maximum contact and effective control. If the target were stems, the ground, or the soil, this type of nozzle would be less suitable, since those areas don’t require thorough foliar deposition.
