Definitions
- the present invention relates to an aqueous suspension pesticide composition.
- the aqueous suspension pesticide formulation is also called a flowable formulation, and is a dosage form in which particles of a solid pesticide active ingredient (active ingredient) are suspended in water.
- the pesticide active ingredient is finely pulverized, The diameter is generally not more than 15 ⁇ m.
- Aqueous suspension pesticide formulations use water, so they are highly safe, have no concerns about flammability and odor, are easy to store, and have a safe working environment (Agrochemical Formulation Guide, Nippon Pesticide) Society of Agricultural Chemical Formulation and Application Methods, edited by the Society for Plant Protection (1997), p. 35 (Non-Patent Document 1).
- emulsions the basic composition of which is a pesticide active ingredient, an organic solvent, and an emulsifier.
- emulsions can be prepared at low cost because they can be prepared only by mixing and dissolving the pesticidal active ingredient and other raw materials, but in recent years, social demands such as tightening regulations on safety for humans, livestock and the environment have increased. And there is a tendency to shift from emulsions containing organic solvents to aqueous suspension formulations.
- the aqueous suspension pesticide formulation contains the pesticidal active ingredient as particles as described above, the particles grow and grow during storage or storage, and physical stability and medicinal effects deteriorate. There is a risk.
