Shandong Pengbo Biotechnology Co., Ltd. is a high-tech enterprise jointly established by oversea returnees in 2014， and is the undertaker of the national 13th Five-Year Plan. ZNC, Pengbo’s new R&D product, is an ultra-active plant immune inducer (extracts from endophytic fungi of wild plants) derived from the natural ecosystem. The main functions of ZNC are: 1. promoting plant growth; 2. diseases resistance; 3. stress resistance; 4. promoting plant reproduction and development; 5. improving fertilizers’ efficiency 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 so far, 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 cooperated 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. Completed main components analysis, developed detection methods, and completed physical and chemical properties analysis of ZNC; 2. Accomplished research on the efficacy of ZNC when mixed with various fertilizers and applied to different crops in various regions; 3. Studied the mechanism of how ZNC improves fertilizers’ efficiency; 4. 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 registering ZNC as a new category of fertilizer synergist, and is dedicating to the development of new types 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 subverted scientists’ cognition of ultra-high activity and the comprehensive performance of such functional substances. Several papers were published at international top journals thanks to its originality, and Pengbo acquired 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 this paper indicates Pengbo’s internationally leading role on the research of biostimulant， and ZNC became the international common name.
Pengbo has been adhering to its core value of “research & innovation, and scientific services”. We provide high quality raw materials at low cost, offer services for the development of new products for worldwide producers of special fertilizers, and cooperate with strategic partners to set standards for new fertilizer categories.
