Description

Eco-friendly composition for preventing freezing damage on trees}

The present invention relates to an eco-friendly composition for preventing the East Sea of trees, harmless to the environment, has an excellent effect of preventing East Sea, and is easy to use, and thus relates to an agricultural composition widely applicable to trees such as fruit trees, landscape trees, and garden trees. .

The East Sea is observed in the base part of the main stem and the flower eye, especially if the base part receives the East Sea, it must be fatal to the tree. Due to the east sea of the main stem, the bark of the base ruptures or the formation layer becomes brown, and if severe, the main stem of the tree dies. When receiving the East Sea, pathogens such as apple rot disease are easy to invade through the East Sea area, and the movement of nutrients and moisture is not smoothly performed.

The East Sea of the tree bark occurs frequently after February in which the wood structure is not sufficiently hardened and early winter and dormant breakdown occurs, that is, when the strength to withstand the East Sea is weak.

The incidence of the East Sea may vary depending on the degree of hardening of the tree, the nutritional status of the tree, the damage of the pest, the duration of low temperatures, and the topography. In the hilly areas where the cold air is stagnant, the East Sea is large, and if the cryogenic temperature lasts for more than 8 hours, it suffers very serious damage.

The Rural Development Administration recommends applying a medicine such as befuran coating to areas affected by the East Sea to minimize pest damage, or to prevent infection of stem blight by applying paint or lime sulfur mixture for exterior walls. Rather, it would be better to prevent the East Sea.

Table 1 below shows the limit temperature of the East Sea according to the type of family initiated by the Rural Development Administration. If the East Sea temperature lasts 6 hours, the damage rate of the East Sea is about 20%.

And species Donghae temperature (℃) And species Donghae temperature (℃) And species Donghae temperature (℃) Apple -30~-35 grape -20~-25 Citron -9 ship -25~-30 Sweet persimmon -14 Tangerines -7 peach -20~-25 Feeling -17 Orange -4

So far, as a way to prevent fruit trees in the East Sea, there is a method of wrapping a tree bark with insulating materials such as straw, cloth, and newspaper, or painting it with water-based paint. In addition, grapes in areas that are at risk for the East Sea are also buried in the ground to overwinter.

In addition, the sprinkling method, the installation of a fireproof fan, and the combustion method are also used. The sprinkling method must have measures for securing groundwater and blackouts, and the fireproof fan must also have measures for blackouts, and the combustion method has high installation cost and operating cost. , It is not easy to apply in small orchard farms due to problems such as pollution caused by incomplete combustion and fear of forest fire.

In addition, it is also possible to prevent the East Sea by winding an electric heating wire on a tree. When a power failure occurs, the East Sea can be increased, and damage due to excessively high temperature may occur.

Among the easy-to-use methods in fruit farms, the method of wrapping a tree bark using thermal insulation materials is that the pests overwinter in the thermal insulation materials, so the pests and pathogens must be removed and treated safely before the insects are active. Can be prevented. Therefore, if the removal or removal is not too late, the incidence of diseases and pests increases, and if it is removed too early, it is difficult to properly adjust the removal timing of the coated insulating material because it may receive the East Sea when the temperature drops.

When water-based paint is applied to fruit trees for the prevention of the East Sea, the paint contains a wide variety of volatile organic compounds, so these volatile substances can cause air pollution and harm worker health. In addition, since consumers who prefer eco-friendly agricultural products may have anxiety about fruits produced from painted wood, it is necessary to develop eco-friendly products for preventing East Sea even to relieve consumers' anxiety.

On the other hand, as a composition for preventing the defrosting of fruit trees, a composition composed of microcrystalline wax, paraffin wax, surfactant, etc. has been disclosed.However, when the composition is applied to trees by using a sprayer, the composition is somewhat complicated. There is the inconvenience of having to go through the process of boiling with hot water before spraying because the sprayer can clog in the spraying process and clogged (Domestic Publication No. 2016-0118554).

The object of the present invention is to meet the needs of consumers for environment-friendly agricultural products that value the environment, while the manufacturing process of the composition is simpler than in the prior art, the work efficiency is high with a simple method of use compared to the prior art, and the Donghae tree has an excellent anti-freezing effect. It is to develop an inhibitor.

The present invention is a result of continuous research and development for the above purpose,

1 to 20% by weight of zinc sulfate hexahydrate,

10-50% by weight of calcium hydroxide,

1 to 10% by weight of anti-settling agents, and

An environment-friendly composition for preventing defrosting of trees containing 20 to 88% by weight of water was invented.

Organic Bordeaux mixture and lime sulfur are widely used as protective fungicides for fruit trees and flower crops, respectively, a mixture of copper sulfate and lime, and a mixture of sulfur and lime. Another protective fungicide, zinc bordeaux, is a mixture of zinc and lime, and is known to have less damage than lime bordeaux. However, it has not been known that the above-mentioned products have the effect of preventing defrosting of trees. The present invention was completed using zinc sulfate heptahydrate and calcium hydroxide as active ingredients for preventing East Sea.

The content of zinc sulfate hexahydrate is 1 to 20% by weight, preferably 10 to 20% by weight, most preferably 12 to 18% by weight, based on the total composition. If the content of zinc sulfate is too small, the effect of preventing defrosting is deteriorated, and if it is too large, precipitation is undesirable.

The content of the calcium hydroxide is 2 to 50% by weight, preferably 10 to 50% by weight, more preferably 10 to 30% by weight, most preferably 15 to 25% by weight relative to the total composition. If the content of calcium hydroxide is too small, the effect of preventing defrosting is poor, and if it is too large, it is not preferable because of its poor physical properties such as precipitation and hardening.

The anti-settling agent is added to prevent sedimentation to improve physical properties, and may be contained in an amount of 1 to 10% by weight based on the total composition of the present invention.

The composition may further include 1 to 10% by weight of the adhesive relative to the total composition. Any adhesive can be used as long as it is an industrial adhesive. In particular, urea-aldehyde resin and acrylic-styrene copolymer are preferred.

The composition may further comprise 1 to 60% by weight of sulfur, preferably 5 to 20% by weight, relative to the total composition. The purpose of adding sulfur is to prevent the damage of wintering pests due to the sterilization action.

The composition may further include 0.1 to 10% by weight of the thickener based on the total composition.

The composition may further include 1 to 30% by weight of paraffin oil or pine oil based on the total composition. Adding paraffin oil or pine oil has the effect of preventing pests from entering the trees. When the content of these oils exceeds 30% by weight, layer separation occurs and the effect of preventing defrosting is poor, which is not preferable.

The composition may further include boron and molybdenum in an amount of 0.01 to 5% by weight, respectively, to prevent physiological disorders of fruit trees.

The composition may be used by diluting it in water with a stock solution or 2 to 200 times in order to be sprayed or applied to a tree bark.

The composition may be used as an environmentally friendly agricultural material, an organic agricultural material, a fourth type fertilizer, or a microelement fertilizer.

The invention is depicted in more detail by the description of the following examples and figures.

The composition of the present invention can obtain an excellent anti-freeze effect only by spraying once on the sap of fruit tree before wintering, and can be sprayed by diluting it in water without a separate process such as bathing, which is used in most farms. Since it can be treated with a dispensing sprayer, the work efficiency is excellent.

In addition, the composition of the present invention prevents the East Sea of trees, not only extends the life of fruit trees and garden trees, but also enhances their functions, and in particular, in the case of fruit trees, it is possible to stably produce fruit with excellent quality while being safe. Contribute to the increase.

In addition, since the composition of the present invention contains an insecticidal component, it is effective in terms of management of pests.

Test example One: Apple tree East Sea Prevention Effects and Weakness test

The compositions of Examples 1 to 3 prepared above were diluted in water twice. In December, at the apple farm in Bonghwa, Gyeongsangbuk-do, the diluent was sprayed or applied once, from the branch of the apple tree to a height of 1 m above the ground, and the incidence rate and the East Sea Index were examined during the flowering period after 5 months. The number of trees treated was 36 per treatment. Spray treatment was performed using a general distributing power sprayer (EP-925R, manufactured by ASABA), and coating treatment was performed with a brush.

In the case where the composition of the present invention was not treated, Comparative Example 1 was used, and instead of the composition of the present invention, a water-based paint (for pure & suplus interior, no-rupe product) was applied in the same manner as the above, and Comparative Example 2.

Table 3 below summarizes the East Sea incidence and East Sea index.

(No treatment) - 30.6 - 18.6 Comparative Example 2
(Water-based paint) - 13.9 - 5.6 Example 1 16.7 16.7 7.2 6.9 Example 2 13.9 13.9 5.8 5.3 Example 3 13.9 13.9 5.6 5.3 ¹⁾ East Sea incidence rate (%) = (damage/irradiation) × 100
²⁾ East Sea Index = ∑nX/10n×100, where n is the number of irradiations and X is the East Sea degree.
(East Sea level: 0-10 steps, 0 is no damage, 10 is East Sea, 1-9 is daytime
Compared to the degree of damage to the surface area)

Referring to Table 3, as a result of treating the composition of Examples 1 to 3 in the apple tree weekly, the incidence of East Sea decreased by 13.3 to 16.7% compared to the untreated, and the East Sea Index indicating the degree of East Sea decreased by 62.9 to 71.5%. Can be. In addition, the compositions of Examples 1 to 3 obtained anti-freezing effects similar to those of aqueous paint.

In the case of coating treatment, it takes about 2 minutes per tree, whereas in the case of spray treatment, about 1 minute per tree is possible. Therefore, the spraying efficiency is superior to that of the coating treatment by 50 to 100%. When the results of the spray treatment and the coating treatment were compared in Table 3, the spray treatment had a much better work efficiency than the coating treatment, but obtained an equal or higher anti-freezing effect.

After 3 days, 7 days after treatment, and in the new shoot generator where new branches appear, the degree of weakness of the fruit surface, branches, and leaves of the apple tree was investigated, and the results are shown in Table 4 below. In the table below, the ration means twice the reference amount.
