<![CDATA[ABSTRACT Plant pests and diseases threaten horticultural production in Kwau, where farmers often rely on synthetic pesticides without adequate understanding of safe use, human and environmental risks, or pesticide resistance. This community engagement introduced plant growth promoting rhizobacteria (PGPR) as a biological approach to plant pest organisms, using local materials to lower cost and reduce travel to Manokwari for chemical purchases. Sessions at the Kwau village hall and a demonstration in a farmer’s garden delivered plain-language guidance on PGPR concepts, simple production, and safe application. Farmers participated actively and responded enthusiastically, indicating greater awareness of biological control and a practical entry point for using PGPR. Lasting benefits will depend on structured follow-up with farmers and local institutions.
