Core Viewpoint - The innovative "three-dimensional immunity" control technology for wheat stem rot, developed by the Vegetable Disease Control Innovation Team of the Chinese Academy of Agricultural Sciences and East China University of Science and Technology, has shown effectiveness in the Huang-Huai-Hai wheat region, achieving a control efficacy of 68.18% without the use of chemical fungicides [1][2]. Group 1: Technology Development - The "three-dimensional immunity" technology combines seed coating with immune activators and foliar spraying during the regreening period, enhancing the plant's resistance to pathogens [1][2]. - The immune activators developed have a primary function of boosting crop immunity rather than exhibiting strong bactericidal or fungicidal activity, thus preventing the development of pathogen resistance over time [2]. Group 2: Field Application and Results - Demonstration applications of the technology began in October 2024 across major wheat-producing areas in Shandong and Henan, targeting regions with high incidence of stem rot [2]. - In high-density trials, the white ear rate for conventional treatments using only fungicides was 5.3%, while the rate for immune activator-treated plots was significantly lower at 0.6% [2]. - The results from various regions, including Henan and Shandong, confirmed the cross-regional applicability of the immune activators and the "three-dimensional immunity" technology [2]. Group 3: Future Research and Funding - Future research will focus on optimizing the application techniques of immune activators to further enhance field control effectiveness and expand demonstrations in the Huang-Huai-Hai wheat region [2]. - The technology has received funding from the National Key Research and Development Program for the "Creation and Industrialization of New Immune Activators" [2].
