First, you need to make sure your sprayer is in top condition before spring, and then maintain your sprayer throughout the growing season. Sprayer maintenance includes checking fluid levels, lubricating necessary components, calibrating sprayer monitors, and more.
This sprayer maintenance checklist breaks down what you need to do before you start spraying, as well as daily, weekly and monthly maintenance during the season. At the end of the year, it's important to do a final round of maintenance to keep your sprayer through the winter. This will help protect your sprayer from frost damage and ensure it's ready to use next year.
Every time you spray, you can take multiple steps to optimize efficiency and minimize off-target drift. Reading labels, choosing the best nozzle, calibrating the sprayer and checking the wind speed is critical. You should also use the spray pattern check to make sure you have the correct nozzle spacing and boom height.
There is a small margin of error when spraying insecticides, whether to increase efficiency or to protect adjacent fields. For more effective and safe spraying, remember that small droplets take time to hit the target, droplet size is pressure dependent, small droplets dry fast, and nozzles produce a wide variety of droplet sizes.
