What are plugged nozzles often caused by?

• A. Wrong screen mesh or dirty tank.
• B. Too-new screen mesh.
• C. Thermal expansion of chemicals.
• D. Excessively large spray nozzles.

Answer: (A)

Plugged nozzles happen when the spray solution carries particulates or residues that block the tiny passages in a nozzle. The filter or screen in front of the nozzle is supposed to catch debris, but if the screen mesh is the wrong size for the chemical or the tank is dirty, solids can get through or accumulate and cause clogs. A mesh that’s not appropriate can either let too much debris through or clog from trapped material, and a dirty tank leaves sediments or precipitates that are carried into the nozzle during spraying. Regularly using the correct mesh size, and keeping the tank and screens clean and rinsed between uses, helps prevent plugging. Other scenarios, like chemical expansion or using very large nozzles, don’t directly cause nozzle plugging because they don’t create the blocked passages that clogged nozzles require.
