2. Description of the Related Art Conventionally, agricultural chemicals such as various fungicides and insecticides have been used to keep plants healthy. However, although these pesticides have a certain effect of controlling pathogens and pests and keeping plants healthy, especially when used in crops, the pesticides applied to these crops may adversely affect the health of people. It was More recently, it has been a problem that excessively applied agricultural chemicals contaminate water systems and the like, which is one of the major causes of environmental damage.

Further, various fertilizers, nutrients for plants, etc. are used as growth agents for enlarging leaves and fruits. Among these various fertilizers, there are various fertilizers such as chemical fertilizers, natural fertilizers such as compost, fertilizers in which microorganisms useful for porous bodies such as pulverized coal and zeolite are propagated (Japanese Patent Laid-Open No. 1-22).
No. 64986, JP-A-2-108609), or nutrients containing growth hormone and the like can be exemplified, but these were all growth agents which were sprayed on soil to absorb nutrients from soil. These growth agents are not absorbed from the roots because the applied nutrients are completely absorbed in the soil, or even if they are absorbed, they are a part of the amount applied.
Further, when the plant is unhealthy, it has a drawback that it is not absorbed from the roots. Therefore, these growth agents have not been efficient growth agents that reliably grow leaves, fruits and the like. In addition, the manufacturing process is complicated, especially for natural products such as compost.
Fertilizer also has the disadvantage that it takes time to manufacture.

The content of this water is preferably 5 to 40% by weight, more preferably about 20% by weight.

As the dispersant used in the present invention, bentonite, chito acid, starch, sodium alginate,
Alternatively, surfactants such as polyoxin alkylenes, alkyl sulfates, and lignin sulfonates are preferable because they also function as spreading agents. In addition, this plant growth agent for foliar spray contains various spreading agents for enhancing the spreading property on the leaf surface,
Fertilizers, other growth agents such as nutrients for plants, bactericides, insecticides, etc. may be appropriately added as necessary.

The method of using the foliar spraying plant growth agent will be described below. The above-mentioned plant growth agent for foliar application can be suitably used by diluting it with water about 1000 to 3000 times. At this time, if necessary, a spreading agent, another growth agent, a bactericide, an insecticide, or the like may be appropriately blended as necessary. The diluted plant growth agent for foliar application is applied to the foliage using a sprayer or the like. The number of times of spraying may be set depending on the time, the time of day, the crop, etc., and although it cannot be clearly defined, it is usually about 6 to 8 times before the crop is harvested.

The effects of the present invention will be clarified by showing Examples, Test Examples and Comparative Examples of the plant foliar spraying agent according to the present invention. In the examples, 80% by weight of 100 micron pulverized coal (cedar) was added with 20% by weight of purified water,
