Composition of niclosamide/niclosamide ethanol amine salt effervescent tablet as well as method and application thereof

Abstract

To solve the technical problems, the invention adopts the technical scheme that a composition of a niclosamide / niclosamide ethanol amine salt effervescent tablet comprises the following components in percentage by mass: 1-30% of niclosamide / niclosamide ethanol amine salt, 15-20% of acid source, 15-25% of carbon dioxide source, 5-10% of dispersing agent, 5-20% of water level diffusion spreader and 1-59% of packing. The composition is an effervescent tablet which is convenient to use, and can be directly thrown into rice lands without water for spraying, so that the phenomenon that an ordinary niclosamide / niclosamide ethanol amine salt granular preparation is non-uniform in throwing is prevented, and the effects in preventing and controlling mollusks such as pomacea canaliculata are improved.

Description

technical field [0001] The invention relates to a composition, in particular to a composition, a method and an application of a effervescent tablet of spiroxamine\spiroxamine ethanolamine salt. Background technique [0002] Apple snails are molluscs with large individuals, wide feeding habits, strong adaptability, fast growth and reproduction, and high yield. They are cultivated in various parts of China and can be eaten. However, due to excessive breeding, poor taste and poor market, they were abandoned or escaped in large numbers, and quickly spread to farmland, especially paddy fields. Apple snails eat a lot, and can eat very rough plants, and can also scrape algae, and their excrement can pollute water bodies. Its loss to rice production obviously greatly exceeds its value as a delicacy. The occurrence density of apple snails in rice fields is as high as 16.95 per square meter, and the rice plant damage rate is generally 7% to 15%, up to 64%. A large number of apple sn...

Problems solved by technology

[0007] Spirulina and spirulina ethanolammonium salt are the only molluscicides recommended by the World Health Organization for on-site use in my country. Now the spirulina or spirulina ethanolammonium salt preparations used in my country are mainly 50% and 70% Visibility powder, 25% water suspension agent, is mixed with water and sprayed when used to control apple snails in paddy fields, but due to the large amount of water in paddy fields, it is relatively muddy, which brings difficulties to manual or machine spraying
