    Abstract:
    OBJECTIVE: To evaluate the molluscicidal effect of the META-Li (40% META liquid formulation) against Oncomelania snails in laboratory and field. METHODS: The experiment of META-Li against the snails by spraying, immersion and climbing-inhibition test was carried out in laboratory. Spray method was performed in the field to compare with the wettable powder of 50% niclosamide ethanolamine salt. RESULTS: In laboratory, the LC50 of META-Li by spraying for 1, 2, 3 days was 0.78, 0.44 and 0.46 g/m2 respectively; by immersion method for 1, 2, 3 days, it was 44.4, 27.4 and 24.8 mg/L respectively. When sprayed with active ingredient 2 g/mW of META-Li in the field, the snail death rate was above 90% after 7 days, similar to that of niclosamide. CONCLUSION: META-Li shows high molluscicidal and climbing-inhibition effect on Oncomelania snails.
