Which type of nozzle is used in herbicide spray?

✅Explanation: Flat fan nozzles are the most commonly used nozzles for herbicide spraying. They produce a wide, flat spray pattern that ensures even coverage of the target area, making them suitable for most herbicide applications.

📌 Other Options Explanations:
-Solid cone and triple action nozzles are used for specific applications, such as fungicide or insecticide spraying.
-Impact nozzles are used for high-pressure applications and are not typically used for herbicides.
-Cone nozzles produce a circular spray pattern and are not as efficient as flat fan nozzles for herbicide application.

🔑Key Points:
-These are used largely for broadcast spraying, where foliar penetration and coverage are not essential.
-The best operating pressure for flat fan nozzles is 15 – 30 psi, which produce coarser droplets that are not susceptible to drift.
