General NoteBaybay, Leyte: Philippine Root Crop Research and Training Center, 1989. 53 p. -(PRCRTC Proj. 141)
Summary, Etc.Cassava and yam seed pieces were evaluated in this project. In study 1, the crude extracts from several plant species previously reported as having pesticidal activities were used in the preplanting treatment of cassava cuttings to substitute commercial pesticides used against the white peach scale insect, Pseudaulacaspis pentagona (Targioni-Tozzetti). Of the substances evaluated and bioassayed, extract from Asiatic bitter yam Dioscorea hispida Dennst was most effective at a concentration of 5.0%
