And the production comprises that: 1, preparing materials as soapberry, potato or soapberry; 2, preparing weak alkali solution; 3, extracting saponin; 4, preparing killer. The invention can prevent mollusk with low cost.

Description

technical field [0001] The invention relates to the technical field of medicaments for preventing and controlling harmful molluscs, in particular to a molluscicidal medicament for preventing and controlling harmful molluscs prepared by mixing plant extracts as raw materials and a preparation method thereof. Background technique [0002] At present, due to the adjustment of the rural industrial structure, the area of ​​barren grass continues to increase. Harmful molluscs such as snails, slugs, alien organisms, apple snails, oncomelanias, cone snails, and fine drill snails are harmful to crops, especially to green leafy crops such as vegetables. It is becoming more and more serious and brings immeasurable losses to agricultural production. For a long time, farmers have generally used chemical pesticides or pesticides harmful to natural enemies in the field, such as 6% metaldehyde granules (Mida) or mixed preparations of metaldehyde and carbaryl (Chuwojing No. 3), etc. to contr...
