    The construction of ecological agriculture in China has shifted from the stage of "seeking survival, hoping for food and clothing, and getting rich" to the stage of "seeking ecology, environmental protection, and beauty".
    Traditional pesticides can no longer meet the requirements of agricultural ecological civilization
    .
    It is understood that during the "13th Five-Year Plan" period, China's grain production has grown steadily, stabilizing at more than 1.
    3 trillion catties for five consecutive years.
    In 2020, the average yield per mu will reach 382.
    3 kg, and the contribution rate of agricultural science and technology will exceed 60%
    .
    The amount of pesticide application in China has achieved negative growth for many years, and the pesticide utilization rate of major crops such as rice, wheat, and corn has reached 40.
    6%
    .
    The use of pesticides in crops has dropped from 299.
    99 million tons (100%) to less than 260,000 tons.
    The total use of pesticides in crops across the country has achieved negative growth for four consecutive years, while exports have increased positively for four consecutive years
    .
    Will the reduction in pesticide use affect food production? In response, the reporter interviewed Song Baoan, president of Guizhou University and academician of the Chinese Academy of Engineering
    .
    In Song Baoan’s view, the reduction of pesticides is not at the expense of crop yields and pest control effects, but at the expense of eliminating low-efficiency, high-toxicity, and high-residue varieties, increasing the utilization of pesticides, and using ultra-efficient, environmentally-friendly green On the basis of replacing low-efficiency and old varieties with new varieties of pesticides and biological pesticides, conduct rational use and scientific prevention and control
    .
    "We must see that pesticides are the most effective'weapon' for the prevention and control of outbreaks and devastating pests, weeds, and rodents, and an important strategic material to ensure national food security, but we must not ignore the impact of existing pesticides on human health and environmental ecology To
    deal with the relationship between crop yield and quality, it is necessary to improve the level of scientific use of pesticides, promote the reduction of pesticide application and increase efficiency, develop high-efficiency, low-residue, eco-friendly green pesticides and biological pesticides, and pay more attention to the quality and safety of agricultural products.
    It is an inevitable choice for social development
    .
    " He said
    .
    Since the "Double Reduction Action", China's grain harvest has been harvested year after year, and grain production has steadily increased
    .
    While the output of agricultural products is guaranteed, the quality and safety level has also been significantly improved, and the qualified rate of pesticide residues in major agricultural products such as vegetables, fruits, and tea has stabilized at over 97%
    .
    Song Baoan believes that from the perspective of current agricultural development, there are still problems and contradictions that need to be resolved, and long-term success in green pesticide innovation and scientific use of medicines is needed, and continuous persistence
    .
    He said that four aspects of work should be emphasized
    .
    The first is to strengthen the innovation of pesticide science and technology, improve the quality and use technology of pesticides, and comprehensively popularize scientific and safe drug use technology
    .
    The second is to support the green development policy of pesticides, and further promote the reduction and efficiency enhancement of pesticides and the control of pesticide residues
    .
    Third, we must improve the pesticide use supervision system, clarify the responsibilities and obligations of pesticide users, and regulate pesticide use behavior
    .
    Fourth, we must strengthen the construction of grass-roots disease and pest control systems, continuously improve the ability to guide services in the scientific use of pesticides, strengthen technical training in safe drug use, promote new technologies for comprehensive prevention and control, and strive to achieve scientific selection, precise application, and safe use of drugs, and strive to solve farmers' prevention and control of diseases and insects.
    Difficult
    .
    "It is necessary for the whole society to care and support the development of the pesticide industry, strengthen the original innovation of high-efficiency, low-toxicity, and low-risk pesticides, aim at the development needs of green agriculture, and develop more environmentally friendly and harmless green pesticides
    .
    " He said
