Description

Phytoncide composition and fruit bag using same {A PHYTONCIDE COMPOSITION AND A FRUITING BAG COATED USING THE SAME}

The present invention provides phytoncide as a natural plant extract extracted from at least two species having bactericidal power and insect repellent effect to replace pesticides such as fungicides, which are chemicals used in fruit trees, and eco-friendly fruit bags using the phytoncide. It is about.

In general, fruit farms use fruit bags, that is, fruit bags, to protect fruit from scratches, sunlight and pests during the growing period of the fruit, and to improve the beauty and sweetness by controlling the coloring.

Protection of growing fruit by fruit bags prevents damage from pathogens or pests caused by drugs treated on the fruit bags, and the effect of blocking the pests by covering the fruit bags, which is a phenomenon in which the skin is burned by sunlight. It can prevent the phenomenon and improve the fruit's color development. In this way, the fruit bag may inhibit the color development of the fruit prior to harvesting and then peel off the bag just before harvesting to give daylight to induce even coloration of the whole fruit.

In addition, by appropriately controlling the temperature and humidity in the fruit bag to promote the growth of the fruit or to bring the growth control function to inhibit the growth, it may also lead to an increase in farm household income through the control of the time.

In addition to the above-mentioned action, the fruit bag plays an important role in producing a higher quality fruit by increasing the sweetness of the fruit and preventing bursting of the rind.

In addition, as our standard of living improves, consumers' demand for fruits is gradually advanced and advanced, and the fruit residues of pesticides are strictly managed. Therefore, in fruit cultivation, encapsulation of fruits to prevent pesticides from fruits is becoming more emphasized and generalized.

On the other hand, the core of the fruit cultivation technology is to use a lot of chemical disinfectant during the fruit growing period, so that the war against pests. Pesticides that are in direct contact with the fruit can be prevented by using the fruit bag, but in order to protect the fruit from pests, a high residual drug such as a fungicide, which is a chemical agent in the fruit bag manufacture, is mounted on the bag.

Fungicides treated in fruit bags protect the fruit bags themselves from mold and, in particular, prevent the spread of pests to the fruit inside the fruit bags.

In addition, it is a pesticide used to protect fruit from pathogens, and specifically, antibacterial and antiseptic functions are expected.

Mounting the pesticide in the fruit bag in this way causes a problem that the pesticide loaded on the fruit bag can remain in the skin of the fruit.

In order to fundamentally solve this problem, it is urgently required to search for eco-friendly natural pesticide substitutes that can replace the efficacy of pesticides such as chemical fungicides in fruit bag production.

The present invention has been made to solve the problems caused by the conventional fruit cultivation, in particular the use of fruit bags according to the need for use of the fruit bag to solve the problem of mounting pesticides in the fruit bag for pest control, to be used in fruit bags It is an object of the present invention to provide a phytoncide composition as a plant extract extracted from at least two species which are expected to have a high content of secondary metabolites having high physiological activity such as antibacterial activity.

Further, according to the present invention, 50 to 90% by weight of phytoncide (A) extracted from willow leaves, 5 to 30% by weight of phytoncide (B) extracted from birch bark, and 5 to 20% by weight of phytoncide (C) extracted from ginkgo biloba Provided is a fruit bag using a phytoncide composition coated with a phytoncide composition in which a mixed phytoncide mixture is added to a fruit bag with a phytoncide composition added by adding 2 to 30% by weight to any one selected from paraffin wax, fats and oils, wax emulsions, and fats and oils emulsions.

When the phytoncide composition and the phytoncide composition of paraffin wax, fats and oils, wax emulsions and oils and fats are coated on a fruit bag, the phytoncide mixture is preferably coated in an amount of 0.1 to 10 g per basis weight (g / m ² ).

Fruit bag using the phytoncide composition according to the present invention has a similar physical properties compared to the fruit bag treated with a conventional disinfectant and excellent flexibility of the paper can improve the work efficiency, antibacterial compared to fruit bags treated with no treatment or fungicide This is excellent and has the effect of lowering the incidence of the disease occurring in the fruit, the fruit grown by the fruit bag coated with phytoncide according to the invention has the advantage that there is no problem with residual pesticides.

Hereinafter, the present invention will be described in more detail with reference to examples of the present invention.

Willow extracts, ie phytoncide, contain large amounts of (+)-catechin, naringenin, aromadendrin, eriodictyol, sakuranetin and its glycosides, thaxiporin (taxifolin), neosaturanin, p-coumaric acid, aesculin, (+)-gallocatechin and p-coumaric acid It is known that some of them have the effect of antipyretic analgesic. At the same time, it shows strong bactericidal activity against some pathogenic bacteria and fungi and also insect repellent effect against some pests.

In addition, birch extract, that is, phytoncide, contains betulin, tannin, betulapolyentriol, betulapolyentetraol and higher fatty acids, which are effective in combating insects. It is known to have bactericidal activity against some pathogens, and phytoncide as a ginkgo biloba extract has a high content of flavonoids and ginko-glycosides, which have high antibacterial and pest control effects.

Phytoncide extracted from the above trees was conceived to act as a natural bactericidal and insect repellent, confirming the synergy effect when mixing a certain ratio of the phytoncide of the tree according to the present invention plant extracts, so-called It provides phytoncide as a composition in which phytoncide is mixed in an optimum ratio.

In addition, the phytoncide composition according to the present invention is mixed with any one selected from paraffin wax, fats and oils, wax emulsions, oils and fats emulsions used in the manufacture of ordinary fruit bags, and replaced with a fungicide as a chemical agent and coated on the base of the fruit bags.

In Table 1, the fruit bags coated with the phytoncide composition according to the present invention mixed with waxes and fats and oils (Examples 1 and 2) are mixed with conventional fungicides (Comparative Example 3) or fats and oils (Comparative Example 4). Compared with the coated fruit bags, the tensile strength, tear strength, and water repellency were almost similar to each other, and compared with the untreated fruit bags (Comparative Examples 1 and 2), the results were much better.

On the other hand, the flexibility of the paper, that is, the stiffness (stiffness) to measure the degree of stiffness (stiffness) compared to the fruit bag coated with a conventional fungicide, the strength of the phytoncide coated fruit bag of the present invention was shown to be low, this is a conventional fungicide wax B means that the phytoncide coated fruit bag is more flexible than the oil-coated fruit bag. If the fruit bag is flexible, the operation of covering the bag is easier, and thus the work efficiency is increased.

In addition, Example 3, which has a different mixing ratio of phytoncide, has a lower tensile strength, tear strength, and stiffness than that of Example 2, but maintains much higher properties than that of untreated bag (Comparative Example 2). Appeared to be.

In experiments with different amounts of paraffin wax and phytoncide compositions, fruit bags containing 0.5% by weight of phytoncide (Example 4) showed slightly higher strength than untreated fruit bags and had a very low water repellency but 2% by weight of phytoncide. In the fruit bag mixed with (Example 5) showed a higher strength and water repellency than 0.5% by weight.

In addition, the fruit bag (Example 6) mixed with 40% by weight of phytoncide showed high physical properties and water repellency, but after manufacturing, a large amount of paraffin wax remained on the surface of the paper as in Example 7 It was found that the breathability is poor and sticky and the strength is too high, the workability is poor, which will be described later with reference to Table 2.

Therefore, according to the present invention, the fruit bag coated with phytoncide with wax or fat or oil shows similar durability as that of the fruit bag containing the conventional fungicide, but it can be seen that it is more flexible and has excellent workability.

As can be seen in Table 2 above, fruit bags containing 40% by weight of phytoncide (Examples 6 and 7) have a large amount of paraffin wax remaining on the surface of the paper, resulting in poor air permeability, stickiness, and high strength. Due to the poor castle, many problems are expected to occur when apple bags are put on fruit farms.

Therefore, the apple bag of the fruit bag (Example 1) mixed with 20 wt% phytoncide, which exhibited the same paraffin wax adhesion amount as 5.6 g / m ² as Example 1, was found to be suitable and exhibited excellent physical properties and water repellency. Judging.

As can be seen in Table 3, the incidence of layered rot disease of the apple covered with the phytoncide coated apple bag (Example 1) of the present invention showed a low incidence compared with the conventional wax coated apple bag (Comparative Example 3). On the other hand, Example 4 containing 0.5% by weight of phytoncide in fruit bags with different mixing amount showed higher incidence than that of Comparative Example 3, but in Example 5 containing 2% by weight of phytoncide than Comparative Example Low incidence was shown. In the case of the apple bag (Example 6) containing 40% by weight of phytoncide, the incidence of the layered rot disease was very low, but as described in Table 2 above, there was a problem of increase in workability and manufacturing cost.

Therefore, it can be seen that the phytoncide content should be at least 2% by weight to ensure antimicrobial activity as a fruit bag.

As can be seen in Table 4 above, 121 pears covered with phytoncide-coated bag (Example 2) of the present invention were observed. In boats covered with bactericide-treated bags (Comparative Example 4), 7 out of 196 affected measles, resulting in a relatively high incidence of 3.6%. Therefore, the use of the phytoncide composition treated bag of the present invention has been shown to have an effect of reducing incidence close to about 1%.

The present invention is applied as a natural plant extract without the use of pesticides in fruit bags used to protect fruit from scratches, sunlight and pests during the growing period and further enhance the beauty and sweetness by controlling color development during fruit cultivation Phytoncide can be used in fruit bags to control pests.
