Shandong Pengbo Biotechnology Co.,Ltd. is a high-tech enterprise jointly established by overseas returnees in 2014. Some key research and development plans undertaken by Pengbo are listed into the national 13th Five-Year Plan. ZNC, Pengbo¡¯s new R&D product, is an ultra-active plant immune inducer ( extract from endophytic fungus of wild plants) derived from the natural eco-system. The main functions of ZNC are: 1. promoting plant growth; 2. resisting diseases; 3. resisting stress; 4. promoting plant reproduction and development; 5. improving fertilizers¡¯ effect and activating mineral elements in the soil.
¡¡¡¡The crude extract of ZNC is already highly active at the concentration of 1-10 ng/ml. Being the most active compound known at present, the activity of ZNC is 10 times that of brassinolide, 10,000 times that of gibberellin, and 100,000 times to 1 million times that of humic acid, fulvic acid, and alginate. ZNC excels among plant conditioners and fertilizer synergists for its low cost, stable physical and chemical properties, adaptable formulation and processing, and safe utilization.  
¡¡¡¡Pengbo cooperates with more than 10 scientific research teams including Shandong University, China Agricultural University and Shandong Agricultural University for the research, development and application of ZNC and has made certain progress in the following aspects: 1. We have completed main components analysis, developed detection methods, and completed physical and chemical properties analysis of ZNC; 2. We have accomplished research on the efficacy of ZNC when mixed with various fertilizers and applied to different crops in various regions; 3. We have accomplished research on the mechanism of how ZNC improves fertilizers¡¯ function; 4. We have developed enzyme-linked immunosorbent assay for trace and accurate detection of ZNC in fertilizers and pesticides, which is simple and easy to apply.
¡¡¡¡Pengbo has launched the application process for registration of ZNC as a new category of fertilizer synergist, and is dedicating to the development of new type of fertilizers based on ZNC: ZNC urea, ZNC diamine, ZNC potassium sulfate (potassium chloride), ZNC slow controlled-release fertilizers, and ZNC water soluble fertilizers. 
As an immune inducer, ZNC has broken scientists¡¯ knowledge of ultra-high activity and comprehensive performance of such functional substances. Several papers are published at international top journals thanks to its originality, and Pengbo acquires a series of patents centering on ZNC. On May 18, 2019, Shandong Pengbo Biotechnology Co., Ltd. and Shandong Agricultural University jointly had the research paper Paecilomyces Variotii Extract (ZNC) Enhance Plant Immunity and Promote Plant Growth published at the international top journal Plant and Soil. The publication of the paper indicates Pengbo¡¯s internationally leading role on the research of bio-stimulation substances and ZNC as an international vocabulary.
¡¡¡¡Pengbo has been adhering to its core business of ¡°research & innovation, and scientific services¡±. We provide quality raw materials at low cost, and services for the development of new products for worldwide producers of special fertilizers. We cooperate with strategic partners to set standards for new fertilizer categories.
