Farmers often prefer to use botanicals as opposed to commercial synthetics for a number of reasons. Botanicals do not need to be purchased and are, therefore, low-cost (requiring labour inputs but no direct financial outlay). Many farmers also believe that botanicals are safer to use and are more flexible in their usage than commercial synthetics. Botanicals are also often much more available than commercial products as they grow in the local environment. This research has been able to show through farmer participatory trials that some of the plants traditionally used by farmers for stored product protection offer comparable protection to commercial synthetics. Farmers were able to make selections on which plants worked best due to their own comparative analysis and base further decision making on storage options with this new knowledge.
