Pesticides that come naturally. Validated RNRRS Output.


This is one of 280 summaries describing key outputs from the projects run by DFID's 10-year Renewable Natural Resources Research Strategy (RNRRS) programmes.

Summary for Project titles: R7373: Understanding the mechanisms of bio-activity in botanically derived materials used to protect stored grain in farm-level storage systems and R6501: The use of plant materials for protecting farm-stored grain against insect infestation.

Plants with pesticide properties are helping farmers to improve their earnings by reducing the impact of insect pests in storage. Previously, farmers were forced to minimise their losses by selling grain soon after harvest, when market prices are low. Natural pesticides are cheaper than commercial chemicals. They are also readily available, and safer and easier to use. Traditional methods of using these pesticide plants are, however, highly variable. Farmers need reliable information to support their decision making. Participatory trials in Ghana have yielded new knowledge that can revive and modernise farmer practice by optimising the use of botanical pesticides. With this knowledge, farmers can make informed decisions on application concentrations and methods, preparation of the botanicals and the duration of control.
