How will the bio-stimulant and bio-control industry develop in the future? Experts' forward-looking sharing on the CAC Forum
The World Agricultural Network reported that bio-stimulants have developed rapidly at home and abroad. It is reported that the global bio-stimulating hormone production value has reached 2.1 billion US dollars, and is expected to reach about 3.3 billion US dollars by 2021. The development of the industry requires the guidance of laws and regulations, but the current regulations on bio-stimulants are still not perfect. The China Bio-Stimulator Development and Standards Forum was held again during the Shanghai CAC in 2019. This year's forum invited representative experts from home and abroad and industry giants to gather together to discuss the current status and recommendations of industrial development.
Current status and recommendations of the development of biostimulants in China
(International Organization for Standardization ISO TC134 WG1 Convener, Stanley Vice President Liu Gang's share
In terms of registration, according to the strict definition of the law, bio-stimulants have no clear registration status in China. Most of these products are registered in the name of new fertilizers; most microbiological products are registered in the form of microbial agents and microbial fertilizers; individual products, such as amino oligosaccharides and proteins (polypeptides), are registered in the name of pesticides.
China's bio-stimulants are mainly registered as microbial agents and organic water-soluble fertilizers; fertilizers containing bio-stimulants are compounded with microbial fertilizers, humic acid-soluble fertilizers, amino acid-soluble fertilizers, soil conditioners, and medium-weight fertilizers. Registration. The number of registration certificates for biostimulants in 2018 has increased nearly three-fold compared to 2012, of which 92% are biobacteria. Among the bio-stimulant fertilizers in 2018, 38% are amino acid water-soluble fertilizers, 35% are humic acid water-soluble fertilizers, 15% are bio-organic fertilizers, and 12% are compound micro-fertilizers. The number of registration certificates has increased by 1.8 compared with 2012. Times.
The proportion of registration certificates in 2018
There are four problems in the industry: 1) The concept of bio-stimulants is introduced to China later, and it is still in the stage of emerging development; 2) Bio-stimulants are mostly sold with new fertilizers, and users are generally not well aware of them. Further promotion is needed. 3) Bio-stimulants have experienced more than 20 years of development, and have been widely promoted and applied in the planting industry, but lack of leading enterprises, industrial concentration is not high; 4) many of the bio-stimulant products in China The standard is not behind, but there are no classification and safety standards for biostimulants.
In response to these problems, Liu Gang put forward several suggestions for the development of the future bio-stimulant industry: 1) Defining the definition, type and function of bio-stimulants; definitions can be formulated by the Bio-stimulant Alliance or the China Fertilizer Standards Committee; 2) Improve and improve the regulatory system, laws, regulations and testing standards for bio-stimulants; 3) Establish a unified fertilizer and related product regulatory information platform to simplify its circulation and use in the market; 4) The understanding of bio-stimulants is not comprehensive The problem should be to further study the mechanism of action of biostimulants from cognitive materials, understanding active ingredients, genomics, phenotypics, and proteomics.
Drawing on EU regulations and cooperating with peers
Bio-stimulants were first developed and applied in European countries such as France, Italy, and Spain. As the region with the longest development history, the formulation of EU regulations is worth learning. At the forum, Benoit Planques, Chairman of the European Plant Biostimulator Standardization Committee TC455, also shared the EU regulations and recommendations for global industry development. Benoit said that the EU has classified biostimulants as fertilizers for management, and the EU only focuses on its role in fertilizers. In this regard, Liu Gang also proposed that the domestic positioning of biostimulants can be included in the management of fertilizers, rather than as pesticides. In terms of drawing on foreign concepts, Wang Hong, director of the National Fertilizer Quality Supervision and Inspection Center (Beijing) Soil and Fertilizer Testing Center, stressed that domestic thinking should be seriously considered, and there should be no phenomenon of arbitrarily speculating in the market today.
The European Plant Biostimulator Standardization Committee has also established cooperation with Chinese experts to share the experience of standard setting. Benoit also pointed out that many countries use different vocabulary and definitions for bio-stimulants, and product introductions may be ambiguous in other countries, so names and definitions need to be unified everywhere.
Biological control technology
Like biostimulants, as the biological control technology in the emerging field of green agriculture development, experts at the 8th China International Biotechnology Development Forum held during CAC shared their application status with the audience. Introduced new technologies.
Qiu Dewen, a researcher at the Institute of Plant Protection, Chinese Academy of Agricultural Sciences, introduced the current state of application of biological control technologies at home and abroad. He pointed out that fruits and vegetables are the most widely used areas for biopesticide use in the United States. For field crops, seed treatment is an area where significant progress has been made in the use of biological products. Sales of seed treatments are expected to triple by 2020. Due to the strict legal restrictions on chemical pesticides in Europe and the strong demand for sustainable agriculture, the coverage of bio-control technology applications in some areas has reached more than 50%, and greenhouse applications have exceeded 80%, such as the proportion of biological control applications in greenhouses in Denmark. It has reached 98%, mainly using biological agents such as Bacillus thuringiensis, viruses, predatory mites, parasitic wasps and beneficial insects.
According to Qiu Dewen, the most widely used microbial pesticide is Bacillus thuringiensis (Bt), which has found more than 140 crystal toxins. Bt global market annual sales of 4.8 billion US dollars; insect natural enemies (the most successful application is Trichogramma) and Botanical pesticides are also commonly used in biological control products; in addition, new four major bio-pesticide technologies have emerged in recent years: RNA interference technology, soil health repair technology, insect pheromones and plant immune inducers. He also stressed that chemical pesticides are mainly treated, while bio-pesticide is based on prevention. The two types of products can not be compared with the efficacy alone. Qiu Dewen also suggested that according to the advantages and characteristics of these technologies, comprehensive technical integration, based on the characteristics of the occurrence and development of pests and diseases, carry out comprehensive management research, select a comprehensive solution for pest and disease prevention and control suitable for agricultural production in China, so as to serve the country effectively and environmentally. Agricultural Production.
This year's Central No. 1 document proposed to vigorously develop the production of green high-quality agrochemical products, and focus on agricultural fertilizer-saving and medicine-saving actions. Two forums on bio-stimulants and bio-control technologies have built a platform for knowledge sharing, exchange of experiences, and promotion of new technologies to promote the more efficient development of green agriculture in China.
