である。2. Description of the Related Art Conventionally, golf course turf has been protected from pests and insects,
Large amounts of insecticides, herbicides, and fungicides and fertilizers are used to grow. Prefectural governments provide guidance on the proper use of pesticides and the total amount of pesticides to prevent environmental pollution from pesticides. On the other hand, private companies sell a variety of pesticide products and removal systems. Among them, few of the countermeasure products can remove many kinds of pesticides immediately and can maintain the removal effect for many years. Recently, a pesticide adsorbing and decomposing agent in which an adsorbing substance such as activated carbon is blended into a porous sintered body obtained by firing a metal oxide composed of silicon dioxide, calcium oxide, aluminum oxide, iron oxide, manganese oxide, magnesium oxide, and potassium oxide (Japanese Patent Laid-Open No. 4-10035)
However, it is unlikely that many kinds of pesticides can be expected to have long-term removal effects. At the present time, there is no countermeasure product for simultaneous removal of pesticides and nutrients. Furthermore, with regard to the removal system, the introduction of the system and the maintenance and management thereof have a large economic load at present.

た。Experimental Example 4: Pesticide removal ability (field experiment) A water pipe is provided at the bottom of an experimental field having a width of 2 m and a depth of 2 m, a remover having a thickness of 5 cm is laid, and the upper part thereof is widely used in golf courses in the Chubu region. After mixing a mixture of mackerel soil and Kiso sand, the grass was spread 30 cm and vegetated, and an experiment on removing pesticides was performed.

Spray at a rate of 1 liter per hour.
Water equivalent to 0 mm was evenly sprayed on the experimental field, and the water discharged from the water distribution pipe was analyzed. Using the porous ceramic-based remover of Example 3 of the present invention and a commercially available pesticide adsorbent as the remover, the concentration of the pesticide in the effluent was measured, and the results are shown in Table 4.
