    Another growing season is coming soon, and farmers who want to make efficient application of pesticides should pay close attention to sprayer maintenance, said Mr. Zhong, Eagle Brother’s drone spraying expert with 10 years experiences in the sector. He also recommends following 5 common tips that will help farmers improve spraying efficiency.

    1. Calibrate. Applying chemicals with a sprayer drone that is not calibrated and operated accurately could cause insufficient weed, insect or disease control, which can lead to reduced yields, said Mr. Zhong. Check the gallon-per-acre application rate of the sprayer. This can only be determined by a thorough calibration. Use clean water while calibrating to reduce the risk of contact with chemicals.
     
    2. Mind the nozzle. How the chemical is deposited on the target is as important as the amount applied. Know what kind of nozzles are on your sprayer and whether or not their patterns need to be overlapped for complete coverage. Make sure the nozzles are not partially clogged. Clogging will not only change the flow rate; it will also change the spray pattern. Never use a pin, knife or any other metal object to unclog nozzles.
     
    3. Pay attention to spray pressure. Variations in pressure will cause changes in application rate, droplet size and spray pattern. At very low pressures, the spray angle will be noticeably narrowed, causing insufficient overlap between nozzle patterns and streaks of untreated areas. High pressure will increase the number of drift-prone droplets.
     
    4. Avoid the dreadful drift. Spray drift wastes more chemicals than anything else. Don’t spray when the wind speed is likely to cause drift. Keep the spray pressure low if it is practical to do so, or replace conventional nozzles with low-drift nozzles. Use other drift-reduction strategies: keep the boom close to the target, use drift-retardant adjuvants, and spray in early morning and late afternoon when drift potential is less.
     
    5. Follow chemical and equipment instructions to keep safe. Wear protective clothing, rubber gloves and respirators when calibrating the sprayer, doing the actual spraying, and cleaning the equipment.
