1. Select the right time

According to the temperature change to determine the time

Whether it is plants, pests or pathogens, they all have a suitable activity temperature, about 20-30 ℃, 25 ℃ is the best, then spraying pesticide, not only for the crop is safe, but will also have effect in the active period of diseases and pests.

Hot weather, it should be in the morning before 10 am, after 4 pm to spray pesticide;

Second, when spraying pesticide

1. Grasp the distance and speed

Different crops, plant protection UAV operating height and speed are not the same.

General standard field crops, recommended at 1-1.5 meter high, flying speed is 4 m / s

General fruit trees are recommended at 1.2-1.8 meter tall, flight speed is 2-4 meters / S, according to the flight speed of the day to adjust.
