    A lot of spraying teams tend to complain about lower efficiency of weed controlling when using agriculture drones. Actually it's their ways of improper spraying that caused the ineffectiveness. Here we’d like to share some suggestions from Eagle Brother's experienced spraying team.
     
    1. Spraying at the appropriate growth period of weed
    Usually, it’s the best to spray herbicides in between the two leaves to four leaves period of the weeds. Spraying earlier means few and small leaves, hence much less herbicides is sprayed on weeds; spraying later means larger weed with stronger herbicide-resistance.
     
    2. Weed density must be considered for spraying efficiency
    Spraying at a low density of weeds wastes most herbicides on soil and makes unnecessary re-spraying must be done when fresh weeds come out.
     
    3. Humidity also affects herbicides absorptions
    When the soil is too dry, weeds tends to close their pores on the leaves to prevent moisture from evaporation. Closed pores also prevent herbicides absorptions. Hence spraying at dry conditions is not a good choice. If spraying must be done, it’s better to increase the irrigation for the field or combine larger proportion of water when mixing herbicides before spraying.
     
    4. Water is the natural enemy of weeds
    It's better to keep the field with adequate water. Experienced farmers often keep water cover rice roots to a certain height to prevent weed growing. Thus it’s important to control water depth in the fields after spraying herbicides.

    Other factors should be considered
     
    1. Use clean water when mixing herbicides; it’s better add waters twice to ensure completely and evenly dissolved herbicides
     
    2. Use appropriate nozzles for agriculture drone to produce suitable size of droplet with better adhesion to weed leaves. Too large droplets tend to fall down and too small ones evaporate easily.
     
    3. Avoid spraying at dew conditions or before raining
     
    4. Avoid spraying at hot weather conditions
     
    5. Use specified herbicide additives and safeners when spraying with an agriculture drone
