Diffusion form of quinoclamine (ACN) giant foaming tablet in paddy [Oryza sativa] field water

According to method of treat with paddy field's herbicide, many giant size formulations are under examination. That new type giant size formulations can throw in the paddies. A purpose of this investigation of giant size formulations is to improve farming difficulties such as the shortage of manpower, etc. Regardless of this, it will anticipate that the giant size formulation do not work properly if algae, duckweed (floating weeds), surface soil separations happen on the surface of rice paddies. In these studies, the most important problem was to improve the diffusion of Quinoclamine giant tablets that forming agent and 1 piece net 50g (9% a. i.) for 50m2. Therefore the field test of diffusion form was investigated in the paddy field division into 50m2. Result of the test was as follows; 1. Diffusion form of Quinoclamine in the water was very high within 24hr after treatment Quinoclamine giant foaming tablet in 50m2 paddy field (Fig. 1). 2. In the water, the rises and fall of Quinoclamine concentrations were rapidly than granule formulation (Fig. 5). 3. Disintegration formula of Quinoclamine giant foaming tablet was elucidate for functional formula. These functional formulae showed a change with passage time of Quinoclamine concentration in the water (Fig. 2, 3, 4). 4. Quinoclamine giant foaming tablets were also effective in protecting the environment by it's diffusion foam in the water.
