Reporters on August 16 in Shenyang to participate in the China Pesticide Industry Association hosted the first national pesticide industry innovation exchange and pesticide enterprises CTO Forum learned that pesticide creation to find a new compound is not difficult, difficult to create the compound after the crossing The more stringent environmental protection and safety.

         Guizhou University Vice President, Chinese Academy of Engineering Song Baoan said that the traditional pesticide research and development is very important effect, and green ecological pesticide research and development more emphasis on efficacy and its impact on human and ecological environment of unity. To control the virus disease, for example, the current variety of viral diseases in China, and the existing commercialization of the pharmaceutical species less, a single mechanism of action, many agents only 30% to 50% control, non-target safety is not ideal.

           In the prevention and treatment of viral diseases, small molecule pesticides will play an increasingly important role. The molecular weight of small molecule pesticides is generally less than 500, with ultra high performance characteristics, use per acre less than 5 grams of crops, livestock, and bees, birds, fish, and other beneficial biological safety of silkworm. Understanding the molecular mechanisms of small interfering viral pathogenesis and host resistance to control major, find new molecular targets will be the development of the key. “Song Baoan said looking.

          Data show that China’s pesticide use per unit area is 2.3 times the US, pesticides is the United States 14.7 times. In 2013 the total amount of pesticides in China reached 1.83 million tons, the urgency of the use of pesticide reduction has been the government departments attach great importance. To this end, the Chinese Academy of Agricultural Sciences Institute of Plant Protection, deputy director of Zheng Yongquan for the delegates in detail the application of pesticide reduction technology, said: “through the implementation of pesticide reduction projects, the use of physical, natural enemies, biological control can be reduced by about 20% Of chemical pesticides, the use of aviation plant protection, high pole spray technology can also be reduced by about 17% of the use of pesticides.University research institutes, enterprises and other units in the creation of research and development should pay close attention to these developments.

         “The urgency of today’s agricultural development and environmental protection has put forward new demands and challenges. For the development of new pesticides,  it is not the most difficult to find a new compound in the process of creating new pesticides.” Turning to the difficulties in pesticide innovation and development “Scientists have found that certain compounds have a high level of activity and are tested for toxicity in future R & D, and as the country’s environmental and safety requirements continue to increase, many new compounds are due to the fact that,The toxicity problem had to be eliminated, and it was not enough to keep it.” said Liu Changling, chief scientist at the International Innovation Center.
