3million acres of corn armyworm broke out, and hundreds of plant protection planes rushed to the northwest for disaster relief!
Recently, affected by the drought, there have been large outbreaks of corn armyworm in Shaanxi, Ningxia, Inner Mongolia and other places in China. Armyworms are migratory pests, which are sudden and gluttonous. Corn armyworm eats corn leaves as larvae, and in severe cases, the leaves are eaten up to form bare rods, resulting in serious yield reduction or even no harvest, affecting Foodsecurity.
Corn armyworm infested Shaanxi "Due to the bad weather in northern Shaanxi this year, drought and little rain, wind and sand, Yuyang District, Shenmu City, Dingbian County, and Jingbian County of Yulin City, the area of armyworm outbreak is about 1 million mu." Li Xijun, head of Shaanxi Yunjia Innovation, said.
Since receiving the corn armyworm control project, DJI's agricultural partner, Shaanxi Yunjia Innovative Agricultural Technology Service Co., Ltd., has accumulated an operating area of about 100,000 mu, and dispatched a total of 30 DJI plant protection aircraft and more than 50 pilots.
"After receiving a call from the Agricultural Bureau of Yuyang District, Yulin City, Shaanxi Province on July 1, we began to dispatch planes, and the No. 2 aircraft was in place, and the No. 3 officially entered the field. The T30 can hit about 200 acres per hour, which is very efficient. Li Xijun, head of Shaanxi Yunjia Innovation, said.
"Because the village can't wait, basically every day at 5 a.m., the pilots go to the field, and work until 9 p.m. But if you encounter a large base farm, sometimes you can even work overnight until dawn. We use systemic pesticides, which have a very good effect, and the insects hide in the hearts of corn during the day and come out to eat at night, so the systemic pesticides can effectively avoid the problem of poor operation during the day. ”
At present, the operation in Yuyang District of Shaanxi Province is nearing completion, and the unified defense of Jingbian County and Dingbian County has just begun. "Yesterday, the staff of the Agricultural Technology Center reported that the insect control rate of the plots we operated reached 97%." Li Xijun said.
Inner Mongolia
On the other hand, the Mengxi region of Inner Mongolia (Hohhot, Baotou, Ordos, Bayannaoer, etc.) was released according to the data of the Plant Protection Department of the Agricultural and Animal Husbandry Technology Extension Center of Inner Mongolia, corn armyworm has also broken out about 3.7 million mu, "more than 200 per 100 plants in serious places". Hao Yijun, head of Kaitu Technology, said. Since July 1, DJI's Inner Mongolia agricultural partner Kaitu Technology has gathered a total of 100 pilots and dispatched more than 100 unmanned plant protection aircraft, with a total operation of 690,000 mu.
After receiving the task, Hao Yijun quickly divided the pilots into 10 teams, each team was responsible for a flag (county-level administrative district), and selected a captain from them for unified docking. "This large-scale operation is the first time, and in general, there is no problem in scheduling, and the overall customer evaluation is very satisfactory, and the prevention and control efficiency can reach 85%."
In order to ensure the uninterrupted operation during the unified control of corn armyworm, the after-sales personnel of Kaitu Technology have also increased from the original 5 to 14, "to ensure that ordinary problems can be solved within 2-3 hours, and serious problems can be solved within 7-8 hours." ”Ningxia"I saw that the corn was about to be harvested, but now the corn leaves are almost all gnawed by insects." Villagers said that because of the continuous drought, the armyworms that eat grasses multiply rapidly, and if the corn is not medicated, the corn will soon be gnawed to the stalk.
According to the statistics of the Ningxia Department of Agriculture and Rural Affairs, the outbreak area of corn armyworm has reached more than 70%, about 3.5 million mu, of which 40 plants have reached 100 plants in Tongxin County, Wuzhong City, the hardest-hit area.
"Almost all five prefecture-level cities have erupted. This year, flight defense has played a big role, and we can operate 500-1000 acres a day with a T30. Because the work effect is better at night, the DJI T30's two searchlights allow us to work at night. The villagers are very anxious, and we also hope to complete the control work as soon as possible and efficiently to curb the spread of pests. Liu Xiaojun, head of the Yihe plant protection team, said.
A total of 30 DJI plant protection machines have been dispatched for this time, and the prevention has been started since late June, and a total of 300,000 mu has been operated so far. "The combination of flight defense + strong agents, the insect control rate can reach more than 85%, and we will go all out to win the battle of 'eliminating armyworms' and protect food for the people." Liu Xiaojun said.
