Drones’ Prevention and Control of Diseases and Pests to Protect Rice Production

At present, it is a good time for rice growth, and it is also a period of easy occurrence of rice diseases and pests such as rice planthopper, rice leaf roller, Sheath blight of rice, etc. In order to scientifically and effectively prevent and control the occurrence of diseases and pests, Honghuagang District of Zunyi City has been using drones to carry out rice Pest control work for several days, providing guarantee for grain production and harvest this year.

Recently, in Gongmiba District, Hailong Town, Honghuagang District, clusters of green rice seedlings swayed in the wind and grew happily. The flight prevention personnel poured the prepared pesticide into the water tank of the UAV, and then under their professional operation, three plant protection UAVs turned their rotors and flew over the paddy field, shuttling back and forth to carry out flight prevention operations. “Drug mist” fell from the sky and was evenly sprayed on the seedling leaves, sending a “timely rain” for rice Pest control in the hot summer.

Compared to manual operations, drone spraying has the advantages of reducing prevention and control costs and high work efficiency. It can be completed in just a few hours after a few days of work, and the prevention and control effect is also relatively good, which is well received by the public. “Xie Fuyong, the person in charge of Guizhou Pomegranate Agricultural Development Co., Ltd., introduced that in just five or six minutes, drones can complete the spraying work on about 12 acres of land, and three drones can spray nearly 1000 acres of rice fields in a day.

It is understood that this year, the rice planting area in Honghuagang District reached 15000 mu. The District Agriculture and Rural Affairs Bureau, through purchasing third-party services, carried out drone prevention and control work for more than 5000 mu of rice planting demonstration areas, effectively improving spraying efficiency and Pest control effect, and ensuring high grain yield and income.

“This year, rice leaf roller, rice planthopper and other diseases and insect pests in the whole region are more serious than those in previous years. Our bureau purchased 100000 yuan of Biopesticide such as kalamycin and Beauveria bassiana, and then through the precise application of UAV flight control for plant protection, earnestly do a good job in green prevention and control of rice diseases and insect pests and the rule of unified prevention to ensure the safety of food production.” Yi Jinquan, senior agronomist of the District Agricultural and Rural Bureau, said, They also actively promote the “three new” (new technology, new products, and new machinery) technology of reducing fertilizer dosage and increasing efficiency, using drones to synchronously carry out rice fertilization operations, improving the level of specialization, intelligence, and green fertilization, and adding guarantees for increasing grain production and income.

At the same time, the Honghuagang District Bureau of Agriculture and Rural Affairs also organized agricultural technicians to go deep into the field to carry out a survey of rice diseases and insect pests, carefully check the rice growth and infection of diseases and insect pests, explain the symptoms of rice diseases and insect pests and pesticide control methods, and guide farmers to seize the key nodes to strengthen field monitoring, apply drugs scientifically, and strive to achieve early treatment, small treatment, treatment, and minimize disaster losses.

“In order to effectively do a good job in rice Pest control, we use plant protection UAVs to fly and prevent rice planting demonstration areas, and use pesticides and guide drug use in other areas. We organize farmers to use drugs in a centralized time and work at the same time, so as to effectively minimize the loss of pests and diseases.” The relevant person in charge of the District Agriculture and Rural Affairs Bureau said, next, They will adhere to the mechanism of “unified prevention and control, joint prevention and control, and mass prevention and control”, continue to strengthen the tracking investigation in the field, earnestly do a good job of grain crop Pest control, fertilizer use and other related planting technical guidance, take multiple measures to increase publicity, achieve accurate prevention and control, advocate green prevention and control, ensure that “insects seize grain” achieve actual results, and firmly hold the people’s “grain bag”.

In recent years, Honghuagang District has actively implemented the strategy of “storing grain on the ground and storing grain in technology”, promoted the construction of high standard farmland with high quality, vigorously promoted modern agricultural planting such as mechanical transplanting, drone Pest control and mechanized harvesting, effectively promoted the mechanized and intelligent development of agricultural production, improved the level and efficiency of agricultural production, and guaranteed the safe production of food in the whole district.
