The purpose of this study was to determine the effects of coniferous essential oils (EOs) blended films on insect repellence and crop productivity. Low-density polyethylene (LDPE) film is widely used, especially in agriculture and for food packaging. Ethylene vinyl acetate was blended with LDPE to reduce volatilization of EOs. An EO from Japanese cypress (Chamaecyparis obtusa) was incorporated into the blend film to conduct field research on antimicrobial and insect repellent properties. Among the various concentrations of EO, the highest concentration (2.5%) showed the highest efficiency in terms of pesticidal activity. The ability to inhibit microbial growth can be explained by the lipophilic properties of the EO component, and many studies have already demonstrated this. Agricultural films containing all types of EO have been tested on various crops such as chili, cucumber, Korean melon and have been able to verify their effectiveness in avoiding pests and increasing yields. From these results, it was found that it is reasonable to use a modified film such as a composite film containing an EO for agriculture. Thus, the modified film containing EO has undoubtedly shown impressive potential for reducing the use of pesticides in a variety of ways, not only for agricultural mulching film but also for food and agricultural product packaging. This product is an environmentally friendly chemical and is safe for agricultural and industrial and food packaging applications, among others. In particular, the use of agricultural films significantly reduces the use of pesticides, suggesting that farmers can increase their incomes by reducing working hours and costs, and increasing production.

, 2002). That paper reviews various types of antimicrobial polymers developed for food contact, commercial applications, test methods, regulations, and future trends. Particular emphasis is placed on the disadvantages of each technology.
, 2006), EOs extracted from the leaves of Cryptomeria japonica were examined to test their properties as a silverfish repellent and insecticide. Their study demonstrates the toxic effects of the EO of C. japonica on silverfish. In the non-treated group (0.
Therefore, this study examined the pest killing effect of tree EO-impregnated films and the efficacy of agricultural products in the field.
This study examined the pest killing effect of tree EO-impregnated films and the efficacy of agricultural products in the field. An EO from Japanese cypress (Chamaecyparis obtusa) was incorporated into the blend film to conduct field research on antimicrobial and insect repellent properties.

In this study, six different concentrations (0, 0.1, 0.2, 0.3, 0.4, 0.5%) were tested in the experiment on the effect of vegetable coating on the mortality of nymph (Fig. 2). The second instagram (n = 5) was released from the glass cylinder and the cylinder was sealed with parafilm.
The EO components were identified using SPME (solid-phase microextraction) method with an Agilent 7890B GC & 5975C MSD equipped with a TC-5 capillary column (DB-WAX 60m × 0.25mm × 0.25um, Inlet temp 250 °C).
대상 데이터
Bioassay was performed in the entomology laboratory at Kyungpook National University. Experiments were done with pests such as whiteflies and bean bugs. The pest mortality experiments were carried out with films made by varying the concentration of tree EOs.
Since the amount of resin, the amount of pores, and the size of the film were found to be inversely proportional, 10% EVA resin was used here. The components of the control film and the EO-impregnated LDPE / EVA blend films were investigated.
The experiments in the field were carried out at the Gunwigun Agricultural Technology Center (36.181403, 128.592552) and the farmhouse (35.880297, 128.178027) of Habin-myeon, Dalseong-gun Gyeongbuk province. Cucumbers, chili, cabbages, and yellow melons were visually examined for pest infestation status and yield.
Twenty-five individuals were tested in a chamber at 20 °C in 65% relative humidity.
성능/효과
5% concentration or higher. After 4 days, 100% of all insects died. Unfortunately, there is no previous study on the effects of mulching films on pest control, so the results of this paper cannot be discussed in comparison with previous studies.
6-a). As a result of experiments varying the concentration of EO in the impregnated film, it was found that the insecticidal effect of bean bug appeared in more than 1.5%. As shown in Fig.
This product is an environmentally friendly chemical and is safe for agricultural, industrial, and food packaging applications, among others. In conclusion, the findings of this study suggested that the use of agricultural mulching films (Figs. 8 and 9) possibly can reduce the use of pesticide, suggesting that farmers can increase their incomes by reducing working hours and costs, and increasing production. Furthermore, consumers can also use safe produce.
