Sudha is an organic herbicide used to control weeds that typically grow in the soil within 7 to 10 days after rice saplings are planted. It is made from natural ingredients and is designed to eliminate weeds in an environmentally friendly way.

Farmers across different regions of Bangladesh prepare this type of organic herbicide using their own knowledge, experience, and locally available materials.

One such example is Sudha, an organic herbicide developed by Jitendra Nath Sutradhar, a farmer from Gokul Mathura village in the Rajshahi region. His innovation reflects the practical wisdom and creativity of local farmers in developing sustainable farming solutions.
