Seedling damping-off of carrot (
Daucus carota L.) was occurred in Ibaraki Prefecture, Japan from August to September, 2008. The causal agent was identified as
Rhizoctonia solani anastomosis group (AG) -4 homogeneous group (HG) -I. To the best of our knowledge, this is the first report of this subgroup of
R. solani AG-4 as the pathogen of seedling damping-off of carrot in Japan.

Southern blight of winged bean (
Psophocarpus tetragonolobus (L.) DC.) occurred on Chichijima in Ogasawara (Bonin) Islands in 2011. A pathogen isolated from the diseased plant was identified as
Sclerotium rolfsii Saccardo. An inoculation test confirmed that the fungus was the causal agent of the disease. This is the first report of the disease in Japan.

Anthracnose of Kobunagusa,
Arthraxon hispidus (Thunb.) Makino. and Lychee,
Litchi chinensis Sonn., were found on Hachijo Island of Tokyo Metropolis in 2011. The fungi isolated from the diseased Kobunagusa and Lychee were identified as
Colletotrichum destructivum O’Gara and
C.gloeosporioides (Penzig) Penzig & Saccardo, respectively. Inoculation tests with the isolates to each host plant showed that the fungi were pathogens of the diseases. These new diseases were named as anthracnose, “tanso-byo” in Japanese.

Powdery mildew of dandelion (
Taraxacum officinale) occurred in Ibaraki Prefecture in June 2010. The powdery mildew already had been known as a disease of the plant. However, this disease had not been reported formally. Hence, we analyzed pathogenicity, morphological characteristics and rDNA-ITS region of the causal agent of the disease, and identified the causal agent as
Oidium subgenus
Fibroidium. We formally named the disease ‘powdery mildew of dandelion’ as a new disease of the plant in Japan.

Phytophthora blight of southern star (
Tweedia caerulea) occurred in Kanagawa Prefecture in September 2008. The causal agent was identified as
Phytophthora citrophthora.
Phytophthora blight of southern star caused by
P. palmivora already had been known. However, symptoms caused by these two pathogens were not distinguishable from each other. Therefore,
P. citrophthora should be added as another causal agent of the disease in Japan.

Bacterial leaf spot by
Acidovorax valerianellae is a serious disease for potted hydrangea production in Gunma Prefecture. The effect of temperature and period of high relative humidity on appearance of bacterial leaf spot of hydrangea was investigated. The disease incidence of hydropore at 20℃ and 25℃ were 27.2% and 31.2%, respectively. These incidences were significantly higher than those of 10℃ and 15℃. At 20℃ and 25℃, the disease incidence increased under high relative humidity condition for more than 2 days.

The degree of efficacy and duration period of sterol demethylation inhibiter (DMI) fungicides among many kinds of fungicides against the Japanese pear scab,
Venturia nashicola, were investigated through artificial inoculation to Japanese pear (
Pyruspyrifolia var.
culta) cultivar Kosui grafted seedlings of conidial suspension. Each of the four kinds of DMI fungicides performed with high efficacy, with protective values of 86.7 to 100. A long efficacy duration period was also confirmed, based on the result that there was very little if any occurrence of scab disease as long as 20 days after fungicide application.
