我国生物农药的推广应用现状及发展策略   总被引:3,自引:0,他引:3  
郭荣 《中国生物防治》2011,27(1):124-127
我国生物农药的应用具有良好的基础,在20世纪80年代至90年代曾得到迅速发展.21世纪以来,我国生物农药的应用发展缓慢甚至停滞不前.在我国农作物病虫害防治中,生物防治占防治总面积的8%左右,其中88%为生物农药,12%为人工释放天敌昆虫和昆虫信息素诱杀,而生物农药品种中,杀虫剂占1/3,杀菌剂占2/3.制约我国生物农药推广应用的主要因素,除生物农药自身覆盖的靶标对象少、防效受环境因子影响大等因素外,缺乏激励政策、药效评价标准单一、重基础研究轻应用开发也影响了我国生物农药的发展.近年来,"公共植保,绿色植保"理念的提出和实践,为生物农药的发展提供了平台和手段,通过政府制定鼓励政策、对农民应用生物农药给予补贴、设立生物农药及生物防治技术示范推广项目等途径,可以在政策和技术层面上切实促进生物农药的推广和应用;同时,需要加大农民技术培训力度,不仅为农民提供优质高效的生物农药品种,还要使农民掌握生物农药的应用技术.  相似文献

A range of biopesticides (including, as active substances, bacteria, viruses, fungi, nematodes, protozoa and beneficial insects) is now commercially available for control of insect pests, fungal and bacterial diseases and weeds. The term biopesticide can include pheromones, insect and plant growth regulators, plant extracts, transgenic plants and macroorganisms as well as microorganisms. However, world biopesticide sales in 1990 were estimated to be 120 million USD, representing less than 0.5% of the world's agrochemical market. Out of this, approximately 90% of the biopesticide sales are represented by the bacterium Bacillus thuringiensis for the control of insect pests. Nevertheless, biopesticide sales are estimated to be increasing at 10–25% per annum and sales by the year 2000 are estimated to reach 1000 million USD. This paper looks at the current commercial status and the constraints that are facing industry concerning changing registration, particularly in Europe, the absence of harmonized data requirements, and the increasing costs and delays in registrations that deter the development of new biopesticides.  相似文献

The five‐year value in the compound annual growth rate of the biopesticides sector is predicted to be 16% by 2017 and to produce a global market worth $US 10 billion. Despite this, several impediments occur within the EU that negatively affect biopesticide research and innovation. At present, there are fewer biopesticide‐active substances registered in the EU compared with the United States, India, Brazil and China. The relatively low level of biopesticide research in the EU (6880 ISI papers) versus the United States (18 839), India (9501) and China (7875) relates to the greater complexity of EU‐based biopesticide regulations compared with these other countries. In this light, it is worth noting that tensions may exist between regulators that emphasise the beneficial nature of biopesticides in environmentally friendly crop management and those that adopt a more technologically based approach dependent on a chemical‐pesticide‐driven model. Compared with the other aforementioned countries, far fewer biopesticide products are available in the EU market, mainly as a direct result of the severe regulatory factors present there. The extent to which this trend will continue depends largely on a range of interacting political and/or regulatory decisions that influence environmentally friendly agricultural industries. © 2017 Society of Chemical Industry  相似文献

All living organisms are subject to predation, parasitism or competition from other organisms. The study of these interactions has led to the identification of many potential opportunities for the use of living organisms as biopesticides to protect agricultural crops against insect pests, fungal, bacterial and viral diseases, weeds, nematodes and mollusc pests. A range of biopesticide products (including as active agents bacteria, fungi, nematodes, protozoa, viruses and beneficial insects) are now available commercially for control of insect pests, fungal and bacterial diseases and weeds. However, world biopesticide sales in 1990 were estimated to be $120 million, representing less than 0–5% of the world agrochemical market. Over 90% of biopesticide sales are represented by a single product type, containing Bacillus thuringiensis Berl., for control of insect pests. Nevertheless, biopesticide sales are estimated to be increasing at 10–25% per annum whilst the world agrochemical market is static or even shrinking. There has been a significant renewal of commercial interest in biopesticides as evidenced by the substantial number of alliances forged between major agrochemical companies and biotechnology companies which allow these major companies access to marketing rights to novel biopesticides. This paper reviews the current commercial status of biopesticides and discusses the technical and commercial constraints which have impeded development of biopesticides in the past. Novel developments in R&D, which may enable some of these constraints to be overcome, are examined by reference to a number of specific examples (some of which arise from the author's own experience in a biotechnology company). The future prospects for biopesticides are discussed in the light of technical advances and commercial and regulatory requirements.  相似文献

浅议生物农药取代化学农药   总被引:5,自引:1,他引:5  
近年来,“生物农药”已经有了发展,但也存在一些问题,把活性成分为化学物质的植物农药,抗生素农药等视为“生物农药”,从实用角度看,似为不妥;泛透“生物农药”安全,无公害的,科学依据不足;世界环发大会(1992)提出,到2000年,“生物农药”用量要占农药60%的口号已化为泡影,因为它的依据不足,仅为一个政治号召。  相似文献
