What is the purpose of drop nozzles in agricultural spraying?

The purpose of drop nozzles in agricultural spraying is to apply chemicals directly under the crop canopy. This design allows for more effective targeting of the plants that are being treated, minimizing the loss of spray off the leaves and ensuring that herbicides, pesticides, or nutrients are delivered where they are needed most. By delivering the spray directly to the area that requires treatment, drop nozzles help improve the efficiency of chemical usage, reduce drift, and lower the potential for environmental contamination.

Using drop nozzles can also enhance the penetration of the spray into dense foliage, ensuring better coverage and absorption of the products being applied. This targeted application is particularly beneficial in crops with a tall or dense canopy, where traditional nozzles might miss lower leaves or critical areas.
