発揮することを目的とする。2. Description of the Related Art There have been various attempts by horticulturists to grow lawns, but all of them have the following drawbacks. In order to grow turfgrass soundly, fungicides, insecticides, herbicides, fertilizers, etc. are sprayed as appropriate, as with other crops.
Pests and weeds must be managed. In this pesticide spraying operation, each chemical is diluted with water (1000 times).
２０００2000 times), it is necessary to work separately, so that the spraying work with a tank truck or the like using a large amount of water is not only troublesome, but also damages the lawn grass by the heavy tank truck (2t-4t). There were many. In addition, chemicals diluted and sprayed with water scatter into the air,
It has many drawbacks, such as transpiration, and has the disadvantage that it is not efficient for soil, which is the main site of disease and insect damage. In addition, in the conventional spraying of chemicals by dilution with water, the chemicals often become fine particles, which adversely affect the health of workers due to absorption, contact, etc., and also scatter or leak into the surrounding environment. Caused environmental pollution. There are pesticides such as granules that are not diluted with water, but these have large particles and must be sprinkled after being granulated, which is not suitable for applications such as sterilization. On the other hand, in the case of turfgrass, when grown, the roots grow densely and the air circulation deteriorates.
It is necessary to drill holes (coring, aeration), and spray fine sand called "mesh". I did a lot of work to do that. The present invention has been made in view of such conventional problems, and imparts medicinal components such as sterilization, weeding, and fertilizing effects to the soil itself, and effectively exerts these medicinal effects simultaneously with the application of the soil. The purpose is to do.

A large amount of water is not required for diluting the drug, and no tank truck is required for spraying it. The water is only watered by a sprinkler, which can save a great deal of water. Since the work can be performed at the same time as the sprinkling of the soil, significant labor savings are possible. In the case of dust application, since sand has a higher specific gravity than water, it hardly scatters or evaporates, so that the chemical works effectively and waste is reduced. In particular, the effect on soil, which is a source of pests and weeds, is very effective. The safety for sprayers is also increased. Secondary pollution to the surrounding environment is reduced.
