Over the rice field, the drone flew low over the rice field, flying prevention operations are underway. This year, Haidian district adopted four latest national green prevention and control technologies, all of which were used for the first time in Beijing, in its drone operations against rice and corn.
There are more than 1400 mu of rice planting area in west Beijing. It is now a good time for the prevention of rice blast, rice borer, rice leaf roller and other major diseases and insect pests.
Three national green control technologies were used in the flight control of rice pests and diseases. In view of the moth moth pests using biological feed for lures turning technology, through the extraction of various plants of the monosaccharides, polysaccharides and plant acid, mixed into has to attract and promote adult feeding material, and wrapped it in polymer slow-release carrier, can continue to high concentration in the field of release entice material, can be centralized traps in adult. The other two green control technologies for rice diseases and insect pests are pheromone and pesticide synergism technology and mixed release technology of Trichogramma.
This year, Haidian also adopted a state-level green prevention and control technology — new sustained-release granules developed by the Institute of Plant Protection, Chinese Academy of Agricultural Sciences. Mei Xiangdong, an associate researcher at the institute, said the biopesticide granules can be dropped into the corn horn by drones, which can greatly increase the duration of maize retention and protect maize from migratory pests during this period. At least 36% more effective than conventional chemical pesticide sprays.
