Huayin encounters the danger of armyworms and is actively controlling the drones.

[China Agricultural Machinery Industry News] In recent years, China, Xinjiang, Shandong, Guangxi and other places have carried out the practice of drone "flying defense" crop pests and diseases, in order to explore new ways to use drones to control crop pests and diseases, Relevant enterprises and plant protection departments have also carried out experimental demonstrations of this technology in Kunming, Qujing and Zhaotong, Yunnan Province.
Huayin encounters the danger of armyworms and is actively controlling the drones.

At present, more than 300,000 mu of corn in the 6 counties of Huayin, Shaoguan and Fuping in southern Anhui are suffering from armyworm pests, of which the area of ​​prevention and control indicators is 44,000 mu. In the Huayin and Shaoguan areas where the pests are heavier, helicopters and drones are being used to spray pesticides on heavily pest-borne fields for active prevention and control. As of today (August 3rd) at 3 pm, the city's anti-mite is a serious corn field of more than 20,000 acres, more than half of the round of prevention and control indicators.
At 2 o'clock on the afternoon of August 3, more than 20 staff members from the agricultural and technical departments of Weinan and Huayin used a drone in Xinglefang Village, Luofu Town, Huayin City to spray hundreds of acres of corn. pesticide. Pan Yongli, the villager responsible for contacting the defense business, was too busy to have lunch.
Pan Yongli, a villager from Xinglefang Village, Luofu Town, Huayin City: “Today is the first to carry out the hardest hit areas. Now there is a 300-mu land for prevention and control; some insects are not too serious for human prevention and control. Starting this morning, there may be two more in the afternoon."
The reporter noticed in the field that the corn here is in the pollination period, but many leaves have residual food gaps. There are three or four armyworms on each corn, 6 cm long, and some are still eating corn. blade.
Since mid-July, due to the impact of thunderstorms over the years, corn armyworms are currently occurring lightly in southern Anhui, but they occur in some townships. The city has an area of ​​312,000 mu, accounting for 7.6% of the total planting area of ​​corn. Among them, the area of ​​prevention and control indicators reached 44,000 mu. Serious land occurrences are mainly concentrated in 12 villages in 5 townships such as Qindong, Taiyao, Anle and Huayin City in Shaoguan County. In a particularly serious field, a corn has an average of 8-10 insects. The size of the insect is very large, and the length of the insect is 6 cm. If it is not controlled in time, the corn can be eaten into a polished rod in four or five days, resulting in severe production loss or Never received. At present, the task of protecting the grain and preventing insects is arduous and urgent. The Agriculture Bureau of Weinan City has issued the "Emergency Notice on Effectively Preventing and Controlling Corn Stainworms" to the whole city, requiring the combination of air defense and civil air defense, and promptly suppressing the outbreak hazards, and strive to capture the harvest of autumn grain.
Liu Bo, director of the Agricultural Technology Promotion Center of Weinan City: "Although this armyworm is sudden and explosive, it is still within the controllable range. At present, in addition to the mass defense and mass management of the masses, the unified defense helicopters are used. There are more than 30 drones. There are two main difficulties. First, the insects of the armyworms are 4 to 5 years old, and the resistance is relatively strong. The second is that the height of the corn has reached a high level. To reach the position. The next step is to conduct a detailed investigation based on the effect of prevention and control, in order to decide whether to spray the second medicine. At present, the anti-insecticide rate can reach 80%."
