Description

A kit of fruit bag which chlorine dioxide gas can be released for a long time to prevent damage of blight and harmful insects}

This is a chlorine dioxide sustained-release kit for fruit tree bags that can slowly release chlorine dioxide, which has excellent agility, from the inside of the fruit tree bag to protect the fruit from pests during the fruit cultivation process and to make the fruit look beautiful. It is about the technology.

Due to the recent global warming, the density of diseases and pests is high, so it is urgent to prepare thorough countermeasures by farmers who grow fruit trees.

The increased number of rainy days also contributes to the outbreak of diseases and pests. For example, the peach moth is more common than usual during the rainy season, causing a lot of damage in fruit farms.

In the case of peach moth, it is one of the representative pests of fruit trees that inflict fruit such as pears, peaches, apples, and plums in the early growth and harvest period. This moth is controlled after spawning and larvae invade the fruit. It is difficult and has the property of breaking through and harming the bag even if it is opened.

In particular, the heart-sik moth was designated as a pest for quarantine such as peaches and apples exported to Taiwan in 2008. As a pest that requires special attention to control, stone fruits such as peaches and plums neglected in areas where frequent invasion occurs, and apple trees that are neglected to manage. It is a source of occurrence.

Fruits damaged by heartworm moths are mainly apples, pears, peaches, and plums. The young insects that awaken from the eggs make small holes that look like needles and enter into the fruit, where the juice comes out and forms like dew drops and then dries over time. Although it looks like powdery powder, the larvae that are eaten by digging into the pulp will go to the core and eat the seeds, so that the fruit that has been damaged cannot be eaten at all, and the imago of this moth occurs from early June to late August until early August. The occurrence of moths has accelerated, and the density of the number of adult insects lost in the sex pheromone trap is increasing.

In general, bags for fruit cultivation are used in orchard farms by covering the fruits of fruit trees such as apples, pears, peaches, and grapes to improve the coloring of the skin during the growing period and to prevent damage from pesticides and pests that adversely affect the fruit. As a kind of cover, the fruit cultivation bag, which is used by covering the fruit, is covered before the fruit becomes a fruit, so that the skin of the fruit is not directly exposed to the outside, preventing discoloration of the fruit due to ultraviolet rays, and natural phenomena such as rain and wind. Fruits can be prevented from birds such as magpies, but in the case of pests, they are so small that they cannot be identified with the naked eye, so the fruit tree bag itself has many limitations in being protected from pests by the conditions of the surrounding environment.

Chlorine dioxide (ClO2) to be used in fruit bags was first discovered by Humphrey Davy in 1814, and after being proposed as a disinfectant for water treatment by Berge in 1900, sterilization, odor removal, and bleaching of drinking water in the United States and Europe. It has been widely used for such purposes. In particular, since 1972, it has been discovered that unlike chlorine, chlorine dioxide does not react with organic pollutants in water to produce trihalomethane, a carcinogen, but in Korea, aqueous solutions are treated in parallel with chlorine. The use of iron (Fe), manganese (Mn) and other heavy metals is limited to the extent that it is used.

In addition, one of the advantages of the method of disinfecting chlorine dioxide with excellent agicidal power is that it can be applied at any time before or after harvesting the fruit to reduce the cause of pests at the source, and recently, the ability to control insects has been reported. There is a growing interest in research on the prevention of control.

As described above, chlorine dioxide can kill bacteria or viruses in fruits without being very harmful to the overall environmental field, and it can remove insects and moths that are damaging to fruits. It is expected to have the advantage of being able to grow fruit trees that are beneficial to health.

As the chlorine dioxide provided by the present technology has excellent oxidizing power, it destroys and destroys the tissues of viruses and bacteria, and can eradicate even adult insects and moths that are harmful to fruits, as well as having the ability to remove pesticides. Not only can it provide a great effect in producing high-quality fruits, but it can also greatly reduce the problem of pesticide residues remaining on the skin of the fruit, and development of fruit tree bags for cultivation of high-quality fruit trees that are harmless to the environment is not yet in existence or insufficient. can do.
