The cashew sector is heavily reliant on chemical inputs. Despite increasing awareness of the harmful effects of chemical-intensive farming on producer health, consumer safety, and the environment, the adoption of agroecological practices remains limited. This study shows that agroecological pest control techniques work and have a positive effect on farmers’ net income.
Main message of the chart
The chart shows the increase of yield, expanse, total income, and net income in cashew plots treated with an agroecological pest control method in comparison with non-treated plots. The method used is called Bodoux Mix 10% and 50% and is based on a mix of water, copper sulfate and white lime. It works as a contact and protectant agent, forming a barrier on the plant surface to prevent fungal spore germination and bacterial growth. The method is considered organic due to its mineral basis. However, long-term heavy use should be avoided to prevent copper accumulation in soils.
Implications of the findings
This method is affordable, easy to make and to apply, and has a positive effect on farmer income. Success depends on regular and timely application. It helps to reduce reliance on costly chemical inputs. To promote the method, one should built potential for embedded services and farmer-led distribution.
Data sources
The data are based on comparative field trials conducted in four villages across two Cambodian provinces: Tipo and Salavisai in Kompong Thom, and Rohas and Reak Smei in Preah Vihear. The study was conducted under the coordination of Sthya Sann, and Tolla Chan, HEKS Cambodia.
