Since the late 2000s, a serious Entomosporium leaf spot disease, caused by Entomosporium mespili, has been found frequently on leaves of Eriobotrya japonica and Photinia glabra at a nursery station in Goheung and Jeju, respectively. Studies were conducted to select fungicides that would effectively control Entomosporium leaf spot. Among the three fungicides tested, weekly foliar applications of propiconazole and chlorothalonil effectively reduced disease severity on E. japonica and P. glabra showing control value of 64.1% and 87.6%, respectively. Weekly treatments of thiopanate methyl were less effective. Propiconazole controlled the disease, but, it was phytotoxic to P. glabra.

Securing sufficient planting strip for street shrubs has a limitation. So many different shrubs which have been planted in the streets looks consider its visual aspect rather than growth characteristics. In this study, we compared with the growth condition of planted shrubs and construction condition of its planting strip. $Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$, $Nandina$ $domestica$, $Abelia$ $grandiflora$ were selected in the Busan City, Korea. The planting strips width were 0.5~0.9m which is not relatively different by each species. Species which have narrow growth character of root hair in the natural bed ($Nandina$ $domestica$, $Abelia$ $grandiflora$) have a good growth condition in the street planting strip, oppositely shrubs which have wide growth character of root hair ($Photinia$ $glabra$, $Euonymus$ $japonicus$, $Camelia$ $sasanqua$) have a relatively bad growth condition. Hereupon, there have a necessity which should be select the different shrub species for the planting strip of the street.

Sinomegoura citricola (van der Goot, 1917) is recognized on Citrus unshiu Markovich (Rutaceae), Photinia glabra (Thunb.) Maxim (Rosaceae), and Cinnamomum lourelirii Nees (Lauraceae) from Jeju-do, Korea. Apterous viviparous female, alate viviparous female, and an intermediate morph between the apterous female and alate female are described. This is the first record of the genus Sinomegoura in Korea.

The purpose of this study is to examine noise attenuation according to hedge species and thickness of their leaves. The order of their decrease effects was as follows from the highest to the lowest: Osmanthus asiaticus, Camellia japonica, Pyacantha angustifolia, Photinia glabra, Pittosporum tobira, Nandina domestica, Euonymus japonica, Chaenomeles lagenaria, Aucuba japonica for. Variegatar. The result of the experiment for noise atteunation has shown that woody plant with thicker leaves were better than those with thinner leaves. Multiple Regression Analysis showed Y = 7.653 + 26.530 X ($R^2$= 0.385). The order for the subjects according to their effects on noise attenuation is as follows from the highest to the lowest: Camellia japonica, Nandina domestica, Pittosporum tobira, Taxus cuspidata, Chaenomeles lagenaria. The noise attenuation level of Camellia japonica was the highest (14.70[dB]), while that of Chaenomeles lagenaria was the lowest (6.80[dB]), and its difference between them was 7.9[dB].

In 2019, the ash whitefly, Siphoninus phillyreae (Haliday, 1835), was firstly found on a pear tree in Jinju-si, Gyeongsangnam-do. From occurrence survey, we confirmed that S. phillyreae was occurred in seven cities, Busan, Changwon, Jinju, Gwangyang, Suncheon, Goheung, and Goseong. In addition, seven plants, such as Punica granatum, Pyrus pyrifolia, Cydonia oblonga, Prunus mume, Crataegus pinnatifida, Eriobotrya japonica, Photinia glabra, Pyracantha angustifolia, Lagerstroemia indica, and Malus prunifolia, were detected as hostplants. In this study, we present the first report of this species in Korea and describe the damage caused by S. phillyrease and its taxonomic information.
