Core Viewpoint - The research conducted by scientists at the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences has successfully transformed waste fruits into a natural biopesticide, Ikuamycins, through fermentation, addressing both fruit waste and the need for green pesticide production [2][4]. Group 1: Research and Development - The discovery of Ikuamycins' significant inhibitory effect on various plant pathogenic fungi was made during research on the fungus D39, indicating its potential for industrialization [3]. - The research team shifted from solid fermentation to liquid fermentation to enhance production efficiency, utilizing waste fruits as a cost-effective carbon source for fermentation [4][6]. - The use of waste apple extract as a fermentation medium resulted in an Ikuamycins yield of 20.8 mg/L, achieving a 60% reduction in raw material costs compared to traditional methods [4]. Group 2: Environmental and Economic Impact - Ikuamycins is expected to provide both environmental and economic benefits, as it is produced through microbial fermentation without complex chemical synthesis, thus reducing costs and environmental impact [7]. - The biopesticide has shown effectiveness in controlling diseases in crops such as grapes, tobacco, and wheat, with field trials indicating a disease control efficacy of over 70%, comparable to chemical pesticides [7][8]. - The research promotes the recycling of food processing waste, significantly lowering production costs while enhancing resource utilization [7]. Group 3: Future Prospects - The potential for Ikuamycins to become a new target natural product pesticide is highlighted, as it offers a unique structure not found in current chemical pesticides, which may help reduce environmental pollution and pesticide residues [8]. - The research team is collaborating with pesticide companies to develop formulations of Ikuamycins, aiming to create a closed-loop industry chain that utilizes waste fruits for biopesticide production, potentially processing millions of tons of waste annually [9].
