(57) [Summary] [Problem] For example, even when algae and the like are blown away and the water surface of a paddy field or the like is covered, the diffusibility of the pesticidal active ingredient is good, and the desired local pesticide treatment effect can be obtained. To establish a uniform diffusible granular pesticide formulation and a method of spraying the formulation on the premise of typical spraying. SOLUTION: A homogeneously diffusible granular pesticide preparation containing a pesticide active ingredient, having a particle size distribution of 80% of particles having a particle size of 3 mm or more and having the property of floating on the water surface, and disintegrating on the water surface within 30 minutes and The preparation was applied from the levee of a paddy field under flooding. A method of spraying a uniform diffusible granular pesticide formulation, which is spread over a distance of 5% to 50% of the total paddy area over a distance of at least m. |
