- the dissolution rate in water was lower than that in Comparative Example 13 in the test from 1 day to 35 days after the treatment, indicating that the drug was controlled to be released gradually.
- Example 8 has a lower concentration in water than the former, and the elution of the pesticidal active ingredient is only a small portion at the initial stage and does not continue. Many of the pesticidal active ingredients in the uniform diffusible granular pesticide formulation remain unused! /, Clearly inferior.
- Example 5 and Comparative Example 3 when Example 5 and Comparative Example 3 are compared, the latter has a higher water concentration than the former, and the sustained release of the pesticide active ingredient is reduced due to the absence of a basic substance. You can see.
- Example 5 From the two windward sides of a paddy field having a short side of 20 m, a long side of 50 m, and a water depth of 5 cm shown in FIG. 1, the uniformly diffusible granular pesticide preparation of Example 5 was sprayed by hand. Forty-eight hours after spraying, water is collected from point (A-L) shown in Fig. 1 and analyzed. Was calculated, and the standard deviation of the concentration in water at each point was divided by the average to calculate the fluctuation rate. The results are shown in Table 2.
- the homogeneously diffusible granular pesticidal preparation of the present invention can be prepared by a simple method, and moderately releases the dissolution of the pesticidal active ingredient, whereby the efficacy of the pesticidal active ingredient can be maintained for a long period of time.
- Spray a granular pesticide formulation that can exert its effect and reduce the environmental burden by reducing the release of pesticide active ingredients into the environment, and reduce or prevent harm caused by the pesticide active ingredients, for example, harm to target crops.
- the method enables uniform diffusion throughout the paddy field, and has a remarkable effect of contributing to labor saving in agricultural work.
