Recently, Chongqing continued to explore the "grain" policy, and for the first time implemented the demonstration of using drones to control pests: using the Eagle brothers plant protection drones to drop the eggs of Trichogramma, the natural enemy of rice borers.

A few days ago, Chongqing seed station carried out green prevention and control and unified control of rice diseases and pests in Yongchuan District.

At the observation site in Pu'an village, Linjiang Town, a modified Eagle brothers plant protection UAV, carrying and dropping a product on site - Trichogramma egg ball, can effectively control rice borer diseases. This technology became a highlight of the day's observation activities.

Under the "flying hand" operation, the plant protection UAV evenly drops one Trichogramma egg ball. A small egg ball can hatch 1500-2000 Trichogramma in two days. On average, it only takes 2-4 balls per mu of rice field to achieve the control effect.

According to the person in charge, Trichogramma can parasitize the eggs of the Chilo suppressalis, inhibit the incubation of the eggs of the Chilo suppressalis, so as to reduce the outbreak of the pest of the Chilo suppressalis. It can not only effectively reduce the use of chemical pesticides, but also greatly reduce the labor cost of artificial spraying pesticides. At the same time, it can greatly improve the quality of rice, so as to achieve the green and high yield of rice and increase the income of farmers.

"Pesticide reduction needs this technology to support." Huangzebing, a major grain grower in Pu'an village, decided to use this technology to control more than 500 mu of paddy fields, which not only saved labor costs, but also saved a considerable amount of drug costs.

At present, the rice planting area in Yongchuan District has reached more than 600000 mu. It is understood that June to July is an important period for the formation of rice yield and the prevention and control of major diseases and pests such as rice stem borer, rice planthopper and sheath blight.

"This is the first time in Chongqing." Niuxiaohui, a technician of Chongqing plant protection station, introduced that Trichogramma control of rice borers is a very mature technology, which is the first demonstration of Trichogramma control of rice borers in Yongchuan. Next, the implementation effect of the project will be monitored, and the promotion of green control technology and new and efficient plant protection machinery will be strengthened throughout the city to develop green ecological agriculture for food quality and safety Provide effective technical support for high-quality agricultural development.
