Repeated exposure to crop losses and heavy reliance on synthetic agrochemicals led Ugandan agricultural engineer Diana Annet Nanono to look for alternative approaches to crop protection. Her participation in the Knowledge Hub for Organic Agriculture and Agroecology in Eastern Africa (KHEA) Multiplier Training in 2022 introduced her to practical agroecological methods, including biochar, composting, vermiculture, botanical pesticides and biological crop protection.

Building on this training, Nanono worked with a multidisciplinary team to develop a plant-based organic fungicide using extracts including neem, ginger and lemongrass. Through Raj Garden Fresh, which she co-founded and now directs, the team has combined laboratory experimentation, field testing and farmer feedback to refine the formulation. Field trials have produced encouraging results, while further farmer validation, certification and compliance with national quality standards remain important steps before wider adoption.

Her experience also illustrates the connection between agroecology capacity development and local entrepreneurship. Farmers have been involved in testing and improving the product, helping ensure that development responds to practical crop protection needs. The story highlights how training, knowledge co-creation and research partnerships can support locally developed agricultural innovations while creating opportunities for young agricultural entrepreneurs.
