Evaluation of material from plants of medicinal importance in Malawi as protectants of stored grain against insects
1996
Chimbe, C.M. | Galley, D.J.
Dried and powdered tissue from 12 Central African plants, some of medicinal use in Malawi, were evaluated for their potential in restricting infestation of wheat grain by Sitophilus oryzae and of shelled maize by Prostephanus truncatus. Four of the powders were found to be effective and petroleum extracts from these were tested further. Significant activity against adults and progeny development was exhibited by two of the extracts, that from Dicoma sessiliflora being slightly more effective than that from Neorautanenia mitis.
