Description

The present invention relates to a multifunctional control agent for agricultural products using charcoal and wood vinegar.

When storing agricultural products, care must be taken to prevent the invasion of pests and mice and measures against humidity. For example, measures such as the use of hawk's claws and storage in the refrigerator have been taken to preserve rice. However, in addition to concerns such as odor transfer to agricultural products and lack of storage space, there are few methods that combine multiple effects, so it has been considered to use several countermeasures together.

By the way, charcoal is known to be a porous substance having many fine pores. The adsorption action of substances produced by the micropores is effective not only for deodorizing effect but also for humidity control and adsorption of toxic substances, so that it is used not only as a fuel but also as a deodorant.

In addition, in the charcoal production process, the wood vinegar obtained when carbonizing wood is used as a repellent for pests and rats, a soil conditioner, etc., and if it is sprayed on the leaves, it will prevent the leaves from being damaged. Is also expected.

By using charcoal and wood vinegar in combination in this way, it is possible to obtain a multifunctional control agent for agricultural products having a plurality of effects such as measures against humidity in a storage place and invasion of pests and rats. However, it is necessary to prevent the deodorizing effect of charcoal from diminishing its effectiveness as a repellent for wood vinegar and preventing the odor of wood vinegar from being transferred to crops.

Therefore, in view of the above circumstances, it is an object of the present invention to provide a multifunctional control agent that does not transfer the odor of wood vinegar to agricultural products by utilizing the properties of both while using charcoal and wood vinegar.

A multifunctional control agent having charcoal enclosed in a breathable bag and an immersion body immersed in a diluted wood vinegar solution, and the accommodating portion accommodating the immersion body is placed in the bag so as to be separated from the charcoal. It is characterized in that the immersion body is separated from the charcoal by being provided.

The diluted wood vinegar is characterized in that the mixing ratio of water and wood vinegar is 100 to 120: 100 to 120.

According to the invention of claim 1, by combining charcoal having a deodorizing effect and a wood vinegar solution that emits an odor that pests and mice dislike, it is possible to provide an environment suitable for storing agricultural products. In addition, by separating the soaked body soaked with charcoal and wood vinegar, the charcoal and the soaked body do not come into contact with each other, and the odor of the wood vinegar soaked in the soaked body can be prevented from disappearing due to the deodorizing effect of the charcoal. it can.

According to the invention of claim 2, when the wood vinegar is diluted, the ratio of water: wood vinegar is 100 to 120: 100 to 120, so that the repellent against pests and rats is superior to the deodorizing effect of charcoal. The effect as can be maintained.

It is a perspective view which showed the whole of the multifunctional control agent which concerns on embodiment of this invention. It is sectional drawing when the multifunctional control agent which concerns on embodiment of this invention is laid down.

Hereinafter, embodiments of the present invention will be described in detail.
As shown in FIG. 1, the multifunctional control agent of the present invention includes an accommodating portion 4 for accommodating the immersion body 3 in a breathable bag 1 using a non-woven fabric or the like in which chip-shaped charcoal 2 is enclosed. When the opening is closed after the charcoal 2 is put into the bag 1, the accommodating portion 4 is configured to form a band-shaped space by suturing two upper and lower parts so as to cross the bag 1. The immersion body 3 housed in the storage section 4 has a paper stick shape, and after immersing the immersion body 3 in a wood vinegar solution diluted with water for 1 hour, the immersion body 3 is sandwiched between the doughs of the bag 1. If the upper and lower parts are sewn together, the charcoal 2 and the immersion body 3 inside the bag 1 can be stored in independent spaces as shown in FIG.

The wood vinegar solution used in the present invention is diluted with water, and the mixing ratio thereof may be in the range of 100 to 120: 100 to 120. Specifically, for the dilution of the wood vinegar solution in the present embodiment, 100 ml of water is mixed with 100 ml of the wood vinegar solution, and it is most desirable to use the mixture in this ratio.

By using the charcoal and the wood vinegar in combination in this way, it is possible to provide a multifunctional control agent for agricultural products that can repel pests and rats and can deodorize and adjust the humidity in the storage at the same time.
However, when charcoal, which has a deodorizing effect and an adsorption effect on toxic substances, and wood vinegar, which is used as a repellent for pests and mice, are used at the same time, the odor of wood vinegar may disappear due to the deodorizing effect of charcoal. Therefore, if the charcoal 2 and the immersion body 3 are physically separated by providing the accommodating portion 4 containing the immersion body 3 impregnated with the wood vinegar solution at the end of the bag 1 containing the charcoal 2, as shown in FIG. Even if the multifunctional control agent is placed sideways on the rice bag 100, the wood vinegar can be kept away from the effective deodorizing range of charcoal as much as possible, so that the wood vinegar whose deodorizing effect of charcoal has volatilized will be erased. The risk can be reduced.

When using the multifunctional control agent of the present invention, there is a concern that the odor peculiar to wood vinegar may be transferred to the surrounding crops. However, by mixing and diluting wood vinegar and water at the above ratios, pests and rats It is possible to prevent the odor from being transferred to the surrounding crops while maintaining its effectiveness as a repellent.

In addition, it is known that vegetables and fruits release ethylene gas that promotes their own ripening, and even after harvesting, they continue to release ethylene gas and proceed with their own ripening, which may cause damage quickly. It was. Therefore, by storing charcoal, which has the effect of adsorbing toxic substances, together with vegetables and fruits, ethylene gas is adsorbed on the charcoal, and aging by ethylene gas can be delayed.
Since the multifunctional control agent of the present invention combines the effects of charcoal and wood vinegar, it is possible to suppress the ripening of the stored crops and extend the storage period, and the crops that are about to be eaten are affected by pests and rats. It can be protected from feeding damage.

Since the multifunctional control agent of the present invention encloses the charcoal 2 and the immersion body 3 impregnated with the wood vinegar solution together in the bag 1, it does not take up any other space as long as there is space for the bag 1. Can be installed. In addition, when the deodorizing effect of the multifunctional pest control agent is weakened, the deodorizing effect is restored by drying the bag 1 containing the charcoal 2 in the sun to remove the odorous components adsorbed by the fine pores of the charcoal 2. Since it can be reused, it can be used repeatedly.

In the multifunctional control agent of the present invention, a paper stick is used as the immersion body 3 to be impregnated with the wood vinegar, but as long as the wood vinegar is impregnated, the material used may be cloth or the like. If the points do not come into contact with the charcoal 2, the number may be two or more. In addition, the shape of the immersion body 3 may be any shape as long as it does not come into contact with the charcoal 2 such as a stick shape or a sheet shape or a tablet shape as in the present embodiment.
Further, the charcoal 2 sealed in the bag 1 is in the form of chips in the present embodiment, but may be in the form of powder.
