Achieving Zero growth of pesticides requires Youth spokesmen

Original title: looking for an image spokesman for the zero growth action of pesticides

"Zero growth in Action" Popularization of Pesticide knowledge held at East China University of Science and Technology.

In February last year, the Ministry of Agriculture issued an action plan for zero growth in chemical fertilizer and pesticide use by 2020. Among a series of specific measures, it is particularly required to strengthen the publicity and training of the zero growth action of pesticides. To this end, the "Zero growth in Action" series of pesticide knowledge popularization public welfare activities initiated by the Zero growth Application and Research Group of the Ministry of Agriculture launched the first stop in East China University of Science and Technology a few days ago. Through a series of activities, such as the on-site demonstration of plant protection drones, the symposium on innovative and integrated development of zero growth in pesticide use, and the launching ceremony of the cartoon image collection activity of "zero growth in action", the concept of zero growth action was sent to university campuses. guide a generation of students to become the "spokesman" of China's modern agriculture.

How will "zero growth" be realized?

Is pesticide good or bad? Most people think it is the latter. But the whole activity tells us that this understanding is biased. Pesticides play an important role in preventing and controlling crop diseases, insects, grasses, rodents and regulating plant growth. The pesticide industry recovers about 200 billion jin of grain loss every year, accounting for more than 15% of the total output, which is equivalent to an increase of more than 100 million mu of arable land to produce grain. With the climate change and the change of farming system, crop diseases and insect pests occur frequently, frequently and repeatedly, agriculture is more and more dependent on pesticides, and the ecological pressure caused by pesticides is also increasing.

The essence of zero growth in pesticide use is to improve the level of agricultural modernization. China, as a major country in the production and use of pesticides in the world, the high consumption and low utilization rate of pesticides are prominent problems in the prevention and control of agricultural diseases and insect pests. "Zero growth" is to achieve "control and improvement" by reducing the number of times of application, reducing the dosage, reducing the loss of pesticides and improving the effect of prevention and control.

"controlling quantity and improving efficiency" is a big topic, which needs to be promoted by innovation. Shan Weili, director of the Drug Administration Department of the Pesticide Control Institute of the Ministry of Agriculture, said: how to use Internet thinking to optimize the supervision mode of the traditional pesticide industry? How to change the current situation of low utilization rate of pesticides? Only innovation.

Can China's pesticide enterprises work?

Will the zero growth of pesticide use affect the sales volume of pesticide enterprises? Will it be snubbed by pesticide and pharmaceutical enterprises? Shan Weili said at the launching ceremony of the cartoon image collection activity of "Zero growth in Action" that the project has been actively participated by a number of enterprises, such as middle farmers Lihua, Yongnong biology, Shangge Road, Binnong Science and Technology, Yanhua Yongle, Sichuan Guoguang, and so on. The "Farm Flyer", Dragonfly Farm Service and Jingbo Nonghua, which participated in the on-site demonstration of plant protection drones, not only demonstrated the performance of plant protection drones, but also demonstrated the innovation of pesticide service mode.

"Agricultural Flying passenger" is a professional plant protection company relying on Anyang Quanfeng Aviation Plant Protection Technology Co., Ltd. Anyang Quanfeng is the first agricultural aviation integrated service provider in China, has developed a number of drones, has a number of patents, and has established a networked management system. Their slogan is: "you farm, I will administer medicine!" To undertake flight prevention operations of more than 2000 mu. " In the next three to five years, Quanfeng Aviation Plant Protection will establish a highly integrated and information-based trans-regional plant protection flight control operation alliance in the country. Yu Lecheng, manager of Anhui Flying Defense Department, told reporters that our "Flying Peasant" just wants to make better medicine and equipment. The future flight defense is to fly towards the drug-saving rate put forward by the user.

Xin Chengyou, manager of the new agrochemical business development department of Jingbo, told the reporter: "the most important thing for pesticide reduction is to study the substitution of compounds and develop pesticides with high efficiency and low toxicity. The common method of using carbendazim is 50 grams per mu, and what we are developing now is 8 grams per mu. Jingbo cooperated with Wuxi Hanhe Company to develop flight prevention drugs three years ago. The previous pesticide preparations were used in sprayers, and the water exchange rate for 1 kg of medicine was 45-50 kg. At present, the water exchange rate is 0.5 kilogram for flying defense. The potion can't be changed. What should I do? We have developed flight defense preparations to solve the problem of drug and mechanical integration. "

What can we students do?

At the demonstration site of the unmanned plant protection machine, Li Yulin, a sophomore majoring in pharmaceutical science in East China University of Science, has been watching. He comes from Xiao County, Anhui Province. His family has 10 mu of arable land and grows wheat and corn. He said he liked his major very much, and using drones to apply pesticides made him feel promising. Yuan Pengtao and Zhu Ling, PhDs majoring in agropharmacy, participated in the organization of the event. They said that such an activity is a big paper.

Xin Zhong, vice president of East China University of Science and Technology, said at the launching ceremony that the social evaluation of pesticides is not too high, but it is definitely not good to eat without pesticides. Our school participates in the zero growth action of pesticides in the hope that through such a national action, the broad masses of students can actively participate in the dissemination, let the whole social science understand pesticides and scientifically understand the safety of agricultural products, so as to promote the process of agricultural modernization in China.

Professor Qian Xuhong, academician of the Chinese Academy of Engineering and expert of the Zero growth of Pesticide use Application and Research Project, gave a popular science speech at the launching ceremony: "Ultimate concern: the Spring of Natural Ecology." His views enlightened the students: first, human sustainable development and the concept of sustainable development began with pesticides. Second, human survival is more and more inseparable from pesticides. Third, the realization of natural ecology is the ultimate concern. He asked: is organic food safe? Related tests showed that the concentration of patulin in organic apples was 4 times higher than that in ordinary apples. Patulin can cause kidney failure. The way out is to develop green pesticides. Is it safe without pesticides? The amount of pesticides used in Japan is larger than ours, but the amount of single pesticide used in Japan is less, so the way out is to use drugs scientifically.

It's time for the students to take action. The task is to produce an endorsement image and get it to correct the name of pesticides. Let it become the commentator of pesticide science, the young gentleman of farmers, the manager of pharmaceutical enterprises, and the supervisor of public opinion. Zhu Hui, chairman of Beijing Huaxia Agriculture and Enterprise Cultural Exchange Center, announced the rules of the event at the launching ceremony. The solicitation includes the names of "Zero growth in Action" cartoon endorsements, supporting roles and equipment of Zero growth families, and Zero growth stories. Supporting roles include images, videos, emojis and other forms. Story scripts can also be displayed in the form of text, animation, PPT and so on. The finalists will have the opportunity to become official promotion ambassadors and contributing writers of Zero growth in Action. The event will last until June 30.
