The invention discloses a molluscicide composition containing metaldehyde and emamectin benzoate, and belongs to the field of chemical prevention and treatment. The molluscicide composition comprises the following effective components: the metaldehyde, the emamectin benzoate and an assistant. The molluscicide composition has very good synergistic effects on prevention and treatment of worms of paddy fields, especially ampullaria gigas; the synergistic ratio of indoor bioassay of the molluscicide composition to chilo suppressalis is (10 to 1) to (1 to 80); a field experiment shows that different dosage forms of two medicine compositions have the very good control efficiency on the chilo suppressalis; the control efficiency of the molluscicide composition on the chilo suppressalis after seven days is over 89%; and the control efficiency of the molluscicide composition on the chilo suppressalis after 14 days is over 87%, and is obviously higher than that of a common agent metaldehyde. The molluscicide composition disclosed by the invention has the characteristics of significant synergistic effects, good control efficiency, low amount and the like, is safe to environment and target organisms, is multi-purpose, is capable of treating other insects (such as chilo suppressalis and tryporyza incertulas) on rice, and has a very good effect on delaying the drug resistance of the ampullaria gigas on the metaldehyde.

The invention discloses a composition containing niclosamide and metaldehyde and a compound suspension thereof. The niclosamide and the metaldehyde are used as active ingredients of the composition, and the mass ratio of the niclosamide to the metaldehyde is (1-50):(1-10). The composition can be applied to preparation of medicaments for preventing and treating trematodiasis. The aqueous suspension containing the niclosamide and the metaldehyde comprises 1-50 percent of niclosamide, 1-10 percent of metaldehyde, 1-5 percent of wetting agent, 1-20 percent of dispersant, 1-10 percent of anti-freezing agent, 0.1-1 percent of preservative, 0.1-1 percent of pH regulator, 0.1-1 percent of defoaming agent, 0.1-2 percent of thickening agent and the balance of deionized water which complements the volume to 100 percent. The aqueous suspension has the advantages of large prevention and treatment spectrum, good oncomelania killing effect, nonuse of an organic solvent, low volatility, low toxicity,safety to people, animals and environments, low granularity, high suspension rate, convenience in use and obvious comprehensive and economic benefits.

The invention discloses a luokuwei-containing compound gastropod-killing composition, the luokuwei-containing compound gastropod-killing composition comprises an active component A and an active component B, the active component A is selected from luokuwei, the active component B is selected from any one of the following compounds: metaldehyde, niclosamide and niclosamide ethanolamine, and the weight ratio of the active component A to the active component B is 1: 60-80:1. The luokuwei-containing compound gastropod-killing composition has a synergistic effect on a plurality of harmful gastropod damaging agricultural production, can reduce the pesticide use amount, reduce pesticide residues on crops, and reduce environmental pollution, is safe to human and livestock, and has good environment compatibility, and diseases have low tendency to produce resistance to the composition.
