Dongguan: The application area of plant protection drones has increased by over 10 times in 3 years

Recently, serious corn pests were found in the Yifangtian Agricultural Park in Nancheng Street, Dongguan. After investigation and analysis by personnel from the Dongguan Agricultural Technology Office, it was determined that the pest was caused by the grassland noctuid moth. The “light cavalry” of Dongguan agricultural technology put forward the prevention and control policy of “curing early and curing small”, and invited the UAV for plant protection to carry out unified spraying and control, so as to timely and effectively kill pests for the agricultural garden. It is understood that in recent years, Dongguan has vigorously promoted the application of plant protection UAVs in crop pest control, and the application area of plant protection UAVs has increased more than 10 times in three years.

In the Fangtian Agricultural Park of Nancheng Street, dozens of acres of corn land are lush and vibrant. However, previously, the corn in the agricultural park was severely damaged by pests. The agricultural park then turned to the agricultural technology department for help, and the municipal agricultural technology office “light cavalry” responded quickly to carry out pest investigation and control technology guidance at the scene.

After being determined by agricultural technicians to be a pest caused by the noctuid moth on the grassland, “said Qi Runquan, an administrator of Yifangtian Agricultural Park. The agricultural technicians proposed a prevention and control policy of” treating early and treating small insects “, and developed scientific medication to control eggs and young larvae, Biological pesticides (Bacillus thuringiensis, cabbage armyworm nuclear polyhedrosis virus) and chemical pesticides (tetrachlorobenzamide, chlorpyrifos benzoamide, methylaminoavermectin benzoate, ethyl polysulfide, indefencarb) can be selected to seize the optimal control period for young larvae and implement integrated prevention and control. It is recommended to use plant protection drones for flight prevention operations to ensure the timeliness of prevention and control. The next day, Yifangtian Agricultural Park invited a professional unified prevention and control organization to use plant protection drones to uniformly spray pesticide on 50 acres of corn, completing the workload that usually takes 3 days in just 3 hours.

It is reported that since 2020, Dongguan Agricultural Technology Office has vigorously promoted the application of plant protection UAVs in pest control such as rice and litchi, supported professional organizations for unified prevention and control, and promoted the social service level of unified prevention and control through demonstration. According to statistics, the application area of plant protection drones in the city has increased year by year from 4600 acres in 2019 to 54200 acres in 2022, an increase of over 10 times in three years.

The relevant person in charge of Dongguan Agricultural Technology Office stated that drone unified defense and control is an important direction for improving the quality and production of modern agriculture. Currently, this technology has become a strong support for high-quality agricultural development. In 2023, Dongguan will continue to promote the application of plant protection drones, achieve mechanized and labor-saving unified prevention and control, improve prevention and control efficiency, effectiveness and effectiveness, and firmly promote the implementation of the strategy of storing grain in the ground and storing grain in technology.
