Embodiment 1

[0024] Embodiment 1: Determination of different binders of 5% spiroxamine ethanolamine salt granules

[0025] The content of each component (by weight) is 5 parts of spiroxamine ethanolamine salt, 3 parts of dispersant polyvinylpyrrolidone, 0.3 part of wetting agent N-oleoyl-N-methyl taurate sodium, diluent white carbon 2 parts of black, after mixing, it is pulverized by a jet mill to obtain a wettable powder with high content and good dispersibility, and then combined with 2 parts of special composite binder (see Table 1 for the composition of the composite binder and corresponding products), the selected sand The base material Jiangsha (60-80 mesh fineness, make up 100 parts), mixed evenly in a wet mixer, and dried in a rotary tunnel kiln to obtain a finished granule. Samples 1-4 were respectively obtained according to the above method.

Abstract

The invention discloses a novel environment-friendly oncomelania killing granule capable of being sprayed and a preparation method thereof. The granule is composed of the following components in percentage by mass: 0.1%-30% of oncomelania killing effective components, 0.1%-3% of dispersant, 0.1%-2% of wetting agent, 0.1%-10% of compound bonding agent and the balance of carrier fine sand. According to the novel environment-friendly oncomelania killing granule capable of being sprayed, intrinsic substances in rivers are selected as base materials; a sand-based granule which has moderate mass, has less influences on production and application equipment and can be slowly released for a long time is provided, so that the problems in the aspects of a production formula and a processing process are successively solved; the invention provides an energy-saving, efficient and environment-friendly novel oncomelania killing product which is suitable for being used in all schistosome prevention regions, and has significant values in the aspects of society, environmental conservation and economy.

Description

technical field [0001] The invention relates to a novel environment-friendly snail-killing granule that can be used for spraying, a preparation method and application thereof, and belongs to the technical field of pesticides. Background technique [0002] Granules are one of the important dosage forms that are developing rapidly at present. It is processed by mixing the original pesticide, carrier and adjuvant. Among them, the carrier plays the role of attaching and diluting the original drug, and forms a particle base for the particles. Commonly used carriers include white carbon black, diatomaceous earth, kaolin, flour, corn starch, etc. The auxiliary agents used include binders (coating agents), adsorbents, wetting agents, coloring agents, etc. Its processing methods include kneading method, adsorption method and coating method. The common method of using granules is manual spreading or hole application. Generally, it is not suitable to use pesticide equipment to spray...
