EVALUATION ON MOLLUSCICIDAL EFFECTIVENESS OF MAGNESIUM BORATE ORE POWDER WITH DIFFERENT EXPERIMENTAL METHODS / 中国血吸虫病防治杂志

ABSTRACT

Objective To validate the molluscicidal effect of magnesium borate ore powder (MBOP), and explore the mechanism for providing the scientific basis for the field use. Methods The experiments were performed by the Copper Coin method, Volatilization method and Immersion and Sprinkle methods recommended by WHO. Results The MBOP can't kill the snail by the volatilization. The molluscicidal effect was well by the Immersion and Sprinkle methods. The acted effect was quick by using the Immersion method while the effect was more stable by using the Sprinkle method.LD_(50) of the Sprinkle method (27℃,4 days) was 4.07 g/m2. Conclusion MBOP's molluscicidal effectiveness is well, the action appears gradually and the effect is stable. The possible mechanism of MBOP might act through some dissolved components.
