Qianjiang, Chongqing: Drone air defense helps mulberry garden winter management

At present, more than 90,000 acres of mulberry gardens in Qianjiang District, Chongqing are entering a critical period for pest and disease prevention and control. In Baishi Town, the local government started winter management of mulberry orchards in advance, using drones to spray pesticides to accurately control mulberry borer moths, mulberry loopers and other harmful organisms to ensure the healthy growth of mulberry trees.

In Baishi Town, multiple plant protection drones took off and sprayed highly efficient and low-toxic agents on contiguous mulberry orchards. In less than two hours, the aerial control operation of more than 100 acres of mulberry orchards was successfully completed. Winter management of mulberry orchards is the key to sericulture production in a year. This year, due to climate reasons, the time is slightly advanced.

Zhou Guangfu, technician at the Silkworm Cocoon Station in Baishi Town, Qianjiang District: Winter is about to begin, and we apply sealing chemicals to the mulberry orchards, mainly to kill various insect eggs, reduce the impact of diseases and insect pests, and avoid affecting the development of mulberry trees in the coming year. For example, the 400-acre mulberry garden in our village used to be sprayed manually, which took nearly a month. Now, drone spraying can be completed in about two days, which is very efficient.

There are more than 6,000 acres of mulberry orchards in Baishi Town, which are mainly distributed in mountains and hills. Compared with traditional manual spraying, the use of drones for flying defense is not restricted by terrain. The spraying of pesticides is more uniform and can avoid mulberry trees to the greatest extent. It is more advantageous in terms of control effect and efficiency when attacked by pests and diseases.

Hua Xueyu, Deputy Secretary of the Party Committee of Baishi Town, Qianjiang District: This year we started the winter management of mulberry fields in advance, mobilized three large drones, and carried out aerial control of diseases and insect pests in the mulberry fields in the town in sections to ensure that no dead ends were left. Each drone can carry 20 to 30 liters of liquid medicine, and the flying defense area of one sortie is about 10 acres. With the help of technology, mulberry orchard management is made more convenient and efficient, contributing wisdom and strength to rural revitalization.
