Abstract

The present invention relates to niclosamide colloidal suspension and its preparation process. The niclosamide colloidal suspension is ropy fluid comprising solid niclosamide, water and several assistants. It is used for killing rice field snail, Fushou snail and schistosome. It has high pesticidal effect and is superior to oil emulsion, wettable powder and other conventional forms.

Description

[0001] The technical field of the present invention [0002] The present invention relates to a novel composition of niclosamide for use as a molluscicide. More specifically, the present invention relates to a niclosamide suspension. The above-mentioned colloidal suspension has good environmental compatibility, is used in an appropriate amount, and has better drug efficacy than conventional pesticide formulations. Background technique [0003] The chemical name of niclosamide is 2',5-dichloro-4'-nitrosalicylic acid aniline (2',5-dichloro-4'-nitrosalicylanilide). Niclosamide can be used as a molluscicide in agriculture, by killing its parasitic molluscs, such as snails, and snails are also used as agents for the prevention and treatment of schistosomiasis. There are mainly two dosage forms in the prior art: emulsifiable concentrate and wettable powder. Because of the use of organic solvents in the processing of em...
