Resultantly, many farmers have to rely on traditi onal methods of pest control. Among these is the use of pesti cidal plant extracts and this paper reports on the fi ndings of a study that undertook to compile an inventory of plants that are used in pest control in one part of the developing world, namely, Masaka District of Uganda. The paper reports that the study found that thirty-six (36) plant species are used. Thirty-fi ve (3 ) of these were found to belong to twenty-one (21) families. The paper adds that, of these, the Asteraceae family is the most commonly used followed by the Solanaceae family. It was noted that although some of the plants are scienti fi cally well established (e.g. Azadirachta indica, Melia azedarach, and Tagetes minuta), a few are not well known (e.g. Euphorbia ti rucalli, Bidens pilosa, Vernonia amygdalina), hence the need for research on them. Finally, it was established that some of the plants are increasingly rare, which highlights need for their conservati on.enAttribution-NonCommercial-NoDerivs 3.0 United Stateshttp://creativecommons.org/licenses/by-nc-nd/3.0/us/Pest controlPesticidal plantsIndigenous knowledgeArticle
