Following fall herbicide applications, it’s important to clean your sprayer before storage. Proper winter storage can lead to more effective herbicide applications in spring.
Consider these tips before storing your sprayer for winter:
Clean the tank. Make sure there is nothing left over in the sprayer from this season that could harm your crops in spring. Read labels carefully to learn how to clean your tank correctly. Pay close attention to areas where contamination occurs first, including filters, nozzles, tips and joints.
Clean the lines. To prevent stretching hoses and broken or leaking lines, thoroughly drain all lines and hoses. Water remaining in stored sprayers can potentially freeze and burst lines on the sprayer, especially in geographies with extreme cold temperatures if it is not stored in a heated area. Run antifreeze through the system instead of water after the rest of the sprayer is cleaned to help prevent lines from freezing. In spring, run water through the system to flush out the antifreeze.
Check nozzles. Winter is a good time to check nozzles on your sprayer to make sure everything is working correctly for the following season. This also provides the chance to change nozzles if they did not perform as expected during the season or if the use from the season has worn the nozzles to a point where they should be replaced.
