摘要

In order to setting the control standard of Chinese cabbage pests using a drone, the downward wind speed, spraying width, and the number of falling particles and particle size were examined using a water sensitive paper with spray different heights (3,4,5 m) and flying speeds (3,4 m/sec). Fore kinds of pesticides for aviation control were used to test the perfect lethal concentration and dose for major pests of Chinese cabbage such as Plutella xylostella, Spodoptera exigua and Spodoptera litura. Thenumber of falling particles in spraying pesticides with drones was 80.5% on the upper side, 14.8% on the vertical side, and 4.7% on the back side. The number of falling particles as different spray heights were 3m = 53,4m = 40 and 5 m = 39 particles cm~(-2). The number of falling particles as different flying speeds were 3 m sec~(-1) = 62 and 4 m sec~(-1) =25 particles cm~(-2). In the laboratory test, the perfect lethal concentration and dose of Plutella xylostella was chlorfenapyr SC (20 times, 0.5 ul)andbistrifluron-chlorfenapyr SC (25 times, 0.5 ul). The perfect lethal concentration and dose of Spodoptera exigua was chlorfenapyr SC (20 times, 1 ul), bistrifluron chlorfenapyr SC (20 times, 1 ul), and chlorfenapyr SC (20 times, 1 ul) and bistrifluron-chlorfenapyr SC (20 times, 0.5 ul) for Spodoptera litura. Therefore, the main pest control method of Chinese cabbage using drones is 20 times diluted chlorphenapyr SC or bistrifluoruron-chlorphenapyr SC, sprayed at 3 m height by 3 m sec of going speed.This spraying method will be effective for control of Chinese cabbage pest.
