The hottest green plant protection technology help

Green plant protection technology helps the development of green agriculture in China

human agriculture has a long history, and the use of pesticides is inevitable for historical development and progress. The earliest way of agricultural management was "slash and burn" in the Neolithic age. In order to resist "hunger", human beings have been trying to find various ways to effectively control pests, weeds, rats and other pests

as early as 1200 BC, the ancients used salt and ash to weed, opening the era of natural pesticides

in the 19th century, mankind entered the era of inorganic pesticides dominated by stone sulfur mixture and Bordeaux liquid. Due to the large amount of consumption, together with indiscriminate manufacture and abuse, it urges countries to strengthen legislation and management

France first enacted the pesticide management law in 1905, and the United States enacted the pesticide management law in 1910

in 1944, Bayer company of Germany produced the first organophosphorus pesticide? Parathion marks the entry of human civilization into the era of organic synthetic pesticides based on fossil energy. Its efficiency, economy, simplicity and other advantages have been recognized by everyone

Swiss chemist Paul Hermann m ü ller won the Nobel Prize in 1948 for his invention of DDT

organophosphorus, organochlorine, carbamate and other major categories of pesticides have been developed at a high speed with the advantages of high efficiency, economy and broad spectrum, and have been widely used in the prevention and control of crop diseases and pests all over the world. The practice of using chemical pesticides shows that the use of pesticides can recover% of the total output of crops in the world. Nobel Prize winner noman K. BORLANG said that "without pesticides, human beings will face the risk of hunger"

however, the extensive use of pesticides, especially organochlorine pesticides that are not easy to degrade, has caused environmental pollution and ecological damage. In 1963, Ms. Rachel Carson attacked the problem of chemical pollution in her book silent spring, which awakened mankind's new understanding of chemical pesticides, which further strengthened the management of pesticides. Later, the United States and other countries gradually reviewed the registered pesticide varieties, and took a series of measures such as banning and restricting the use of those found to be potentially dangerous. In the following decades, pyrethroid insecticides, neonicotine insecticides, sulfonylurea herbicides, diamide insecticides and other chemical pesticides with high efficiency and low toxicity appeared successively

the era of "slash and burn" has gone, and the use of chemical pesticides has brought "happiness and harm". However, we are convinced that the development process of pesticides is a process from low efficiency to high efficiency, from high toxicity to green, and from high risk to ecological security. At present, we are in such a critical period of how chemical pesticides can leap from high efficiency to green ecology. The green pesticides with high efficiency, low toxicity, low residue and high selection, represented by chiral pesticides and heterocyclic pesticides, have become the main means or important means to deal with diseases, pests and weeds in the world. The research and development of more efficient, environmental friendly and safer green pesticides has become the focus and hotspot in the field of pesticide research and development in the world in recent years

after more than 30 years of rapid development, China's pesticide industry has leapt from a small country in pesticide production and use to the largest country in the world in pesticide production and use. The supply and settlement market of pesticide products is extremely rich, which has made a positive contribution to agricultural production and farmers' income. However, compared with developed countries, China still lags far behind the international advanced level in the research of new structures, new varieties and environmentally friendly new formulations of green pesticides. In the context of supply side structural reform, the Ministry of agriculture launched the action of zero growth in the use of chemical fertilizers and pesticides in 2015. Based on crop layout, pest occurrence, regional distribution and other aspects, the Ministry vigorously promoted the application of new efficient and safe pesticide products, formulated pesticide application limit standards, developed green prevention and control technology, created new low-risk pesticides, and promoted modern and efficient intelligent precision machinery for plant protection, It has also strengthened technology integration, innovation, transformation and application, organized and implemented the national key research and development plan "comprehensive technology research and development of chemical fertilizer and pesticide reduction and efficiency", and actively promoted pesticide reduction and harm control, promoted pesticide reduction and efficiency increase, and achieved remarkable results by adopting the technology of combining physical prevention and control, ecological regulation, biological prevention and control and precise pesticide application

according to scientific calculation, the pesticide utilization rate of China's three major grain crops of rice, corn and wheat was 38.8% in 2017, which was 2.2 percentage points higher than that in 2015. Huaibei focused on building a 100 billion ceramic aluminum peak. Achieve the goal of zero growth in pesticide use by 2020 three years in advance. Although there is still a certain gap between this level and developed countries, we have seen hope and strengthened our confidence. As long as we persevere, we will be able to achieve better results and win the initiative of green agricultural development

"healthy cultivation of crops" is an important part of implementing the concept of green development and implementing pesticide reduction and efficiency increase. In the future, we should vigorously promote the revitalization of agriculture by quality and green, and continue to promote the innovation and green decomposition of ecological pesticides characterized by the promotion of pesticide reduction and crop health-oriented "whole process immunization" regulation: the application of 1/10000 whole process plant protection technology will be based on "crop health", take "regional governance" as the regulation strategy, accurately implement the "four reduction" measures proposed by the Ministry of agriculture, and provide a whole process solution for the prevention and control of major diseases and pests. With the help of green plant protection technology, China's green farmers can achieve the development of the industry with an excitation frequency of up to 2500Hz driven by the 2D excitation valve, and blaze a path of sustainable agricultural development in line with China's national conditions, so as to make agriculture greener, rural areas more beautiful and farmers richer
