供するものである。When applied to paddy fields, the conventional effervescent pesticide preparations described above cannot exhibit the inherent effects of the active ingredients due to insufficient diffusibility of the pesticide active ingredients in water. However, it has some drawbacks such as damage to rice, so it has not been put to practical use. In addition, the recently proposed method of throwing large-sized granules or tablets into a paddy field by hand has not reached the same uniform and rapid diffusion as the conventional foaming agents. Therefore, the development of new effervescent pesticides to replace this is desired. Accordingly, the present invention provides a novel effervescent pesticide formulation for water surface application, which is uniform and has sufficient diffusibility.

水中に拡散し、均一な処理層をつくるため、慣行の製剤
などと比べて高い防除効果を発現し、薬害も軽減され
る。The following effects are brought about by the implementation of the present invention. First of all, when the effervescent pesticide formulation for surface application of the present invention is applied to paddy fields, the pesticidal active ingredient can be rapidly and uniformly diffused into the paddy field water. This does not change when the pesticide formulation of the present invention is used as it is or when it is added to a paddy field with a water-soluble polymer film.
Secondly, the pesticide formulation of the present invention, which is packaged with a water-soluble polymer film, requires only about 5 to 20 per 10 ares to be thrown into the paddy field by hand. It is unnecessary and economical. Thirdly, since the pesticide formulation of the present invention thrown into a paddy field diffuses the pesticide active ingredient in the paddy water as described above to form a uniform treatment layer, it exhibits a higher control effect than conventional formulations. , Phytotoxicity is also reduced.
