A kind of molluscicide suspending agent and preparation method thereof

Abstract

The invention belongs to the technical field of snail control and particularly discloses an efficient snail controlling suspending agent and a preparation method thereof. The suspending agent takes metaldehyde and / or niclosamide ethanolamine as active ingredients and a natural surfactant as an emulsifying agent, and has an efficient snail controlling effect. According to the invention, the pesticide effect of the snail controlling chemical can be enhanced and the snail controlling agent can keep a high pesticide effect in a wide environment range.

Description

technical field [0001] The invention relates to the technical field of molluscicide, more specifically, to a molluscicide suspension and a preparation method thereof. Background technique [0002] For a long time, people have used metaldehyde and spiroxamine ethanolamine salt to kill harmful molluscs such as apple snails, slugs and snails in mudflats or water bodies in paddy fields. These two drugs are insoluble in water, and metaldehyde It is usually made into granules, which cannot be used in places where spraying operations are required; spiroxamin ethanolamine salts are usually made into wettable powders, which have poor solubility and dispersibility, resulting in difficulty in spraying and uneven concentration of the drug solution, which affects sterility. Spiral effect. In recent years, these two drugs have also been made into suspensions, such as: 40% metaldehyde suspension, 25% spiroxamine ethanolamine salt suspension, etc., but in some environments, the efficacy of...

Problems solved by technology

[0002] For a long time, people have used metaldehyde and spiroxamine ethanolamine salt to kill harmful molluscs such as apple snails, slugs and snails in mudflats or water bodies in paddy fields. These two drugs are insoluble in water, and metaldehyde It is usually made into granules, which cannot be used in places where spraying operations are required; spiroxamin ethanolamine salts are usually made into wettable powders, which have poor solubility and dispersibility, resulting in difficulty in spraying and uneven concentration of the drug solution, which affects sterility. screw effect

In recent years, these two drugs have also been made into suspensions, such as: 40% metaldehyde suspension, 25% spiroxamine ethanolamine salt suspension, etc., but in some environments, the efficacy of these agents is relatively large. inhibition

For example, the efficacy of traditional metaldehyde suspension concentrates is obviously affected by soil moisture. When the dosage is the same, the mollusc killing effect increases with the decrease of soil humidity. The snail effect is very good, but the mollusc control effect is poor in wet areas (field boards, ditches, canals, etc.)

Or the efficacy of the traditional spiroxamine ethanolamine salt suspension is inhibited by the phosphorus-rich environment, especially by phosphate fertilizers

When the phosphorus content in the water body of ditches, canals, paddy fields and other places is high, the efficacy of spiroxamine ethanolamine salt will be greatly inhibited, and the molluscicide effect will be greatly reduced.
