Which material is standard for screens used in most herbicide applications?

• A. 50-mesh monel or stainless steel.
• B. Copper.
• C. Plastic.
• D. Wood fiber.

Answer: (A)

Screens used for herbicide applications must withstand chemical exposure and high-pressure flow without degrading. The standard choice is a corrosion-resistant metal screen, typically Monel or stainless steel, with a fine mesh (about fifty openings per inch). This combination provides durable filtration that resists the chemical environment of sprayer mixes and prevents nozzle clogging while preserving adequate flow. Alternatives fall short for different reasons: copper tends to corrode in many herbicide solutions; plastic screens can degrade, warp, or lose strength under chemical exposure and pressure; wood fiber lacks chemical resistance and durability. So the best match is a fine metal screen made of Monel or stainless steel.
