Field evaluation of anagallis arvensis [SSP latifolia] [saboon el gheit] [primulaceae] as a molluscacidal plant in snail control

ABSTRACT

A field trial in Egypt of the plant molluscicide Anagallis arvensis is described. The application of 132 and 100 mg/Litre powdered whole plant material was made to drain water in October and November 1989. The treatment effect took 24 hours to become fully established. The reduction in the number of alive Biomphalaria alexandria, Bulinus truncates and Lymnaea natalensis was generally more than 90% at a concentration of 100 mg/Liter dry powdered plant material. Lymnaea natalensis snails showed the highest susceptibility to the action of both sooked and dry powder at the different concentrations used. The easy availability of the plant in the rural areas, the high molluscicidal activity of the dry powder of whole plant material and the simple technique of its application recommend the field application of Anagallis arvensis for snail control
