Evaluation of indigenous molluscicides in water against schistosomiasis vectors
Seven varieties of indigenous Phytolacca dodecwulra L'Herrit (Phytolaccaceae) were field-tried for molluscicidal potency.Varieties (U96) and (U95) collected from Kabarole and Kabale respectively were the most potent with LD90 equal to 2.54 and 6.46 mg.t-· respectively. Water bodies ranging between 4,770 and 347,510 Iitres in Kibimba rice fields were treated with up to 50mg.t-· Snails kills were monitored every three months and 92 - 100% mortality rates were realized.HPLC fingerprints revealed the two P. dodecandra varieties to contain highest concentration of the active principle,oleanoglycotoxin- A or lemmatoxin - A.
