With regard to the control method, the substrate was covered with a black and white film, and a part in which a seedling would be planted was cut out. And if a customized yellow sticky trap was inserted so that the substrate in the cut-out part was not exposed after planting the seedling, the invasion of an adult could be prevented, and no larva appeared in the substrate for the whole growing period. It took 8 hours per 10a to cover the substrate and to install the yellow stick trap. On the other hand, in case of not being covered, it took 88 hours to make an effort at chemical control for the growing period. In case of being covered with black and white film, the number of fruits per plant was larger by 7 in comparison with not being covered. The temperature inside rhizosphere was lower by approximately 1 (cid:59282) , and diurnal variation was small. Thus, the temperature was stable. It was possible to apply this method if mulching was performed at the same time in growing in soil as well as hydroponic crops such as paprika, cucumber, and strawberry.","PeriodicalId":14931,"journal":{"name":"Journal of Agricultural Science and Technology","volume":"55 1","pages":"39-44"},"PeriodicalIF":1.2,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89350827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major insect pests included Tea red spider mite (Tetranychus kanzawai Kishida), Garden thrips (Frankliniella intonsa), and Melon aphid (Aphis gossypii glover). And among them, insect pests requiring being controlled were T. kanzawai, and F. intonsa. With regard to seasonal occurrence, T. kanzawai occurred in mid-March, and showed the peak period of occurrence in early June, and then showed that it tended to rapidly decrease. F. intonsa started to occur from early April, and its peak period of occurrence was late-June. With regard to the selection of pesticide, in case of T. kanzawai, 4 types such as abamectin emulsifiable concentrate showed a high control value of 93% or above, and in case of F. intonsa, 2 types such as acetamiprid wettable powder too. No pesticides with which hydrangea was treated had phytotoxicity. On the other hand, with regard to the sticky trap's level of attracting F. intonsa according to color, blue has well attracted F. intonsa until late July, while yellow has attracted a lot from August. Accordingly, only if color was made to be different according to the period, forecast and trap effect were high.

Safety management to prevent the unintentional gene flow by seeds and pollen disperse were well performed. However, as some drainage was blocked or running towards the outside of the confined field, precaution to prevent the unintentional gene flow by the soil runoff needs to be reinforced.
