1. First report of rust on Alnus in New Zealand is Melampsoridium betulinum, not M. hiratsukanum
Authors: McKenzie EHC, Padamsee M, Dick M

A rust disease was first observed in New Zealand on leaves of alder (Alnus viridis) in North Canterbury in 1980, then on Alnus spp. in Nelson in the 1990s and Auckland in 2012. The causal agent was determined by molecular techniques to be Melampsoridium betulinum and not M. hiratsukanum, a species that is currently spreading throughout the northern hemisphere. A rust on Betula nigra and B. populifolia, and earlier specimens from B. pendula, were also confirmed as M. betulinum.

The diversity of cercosporoid fungi in northern Thailand is very high. Eighty-five cercosporoid species were found in northern Thailand including (i) 84 species of true cercosporoid fungi: Cercospora (34), Passalora (7), Pseudocercospora (42), Zasmidium (1); (ii) One morphological similar fungus. Three new species were established, namely Pseudocercospora christellae, P. cratevae and P. radermachericola, while 23 cercosporoid species represent new records for Thailand. In this study, 50 species are described in full descriptions and illustrations, and another 35 species are only listed additionally because they have been described in ―Monograph of Cercosporid from Laos‖ or have previously been recorded from Thailand. The data show that the diversity of cercosporoid fungi in northern Thailand is very high; Meeboon (2009) recorded 166 cercosporoid species from this region.

Phoma selaginellicola was detected on wild invasive plants of Selaginella kraussiana (African club moss). Identification was made based on colony characteristics, pycnidial and conidial morphology and comparison of ITS DNA sequences. This is the first record of the species for New Zealand and a new host species.

Conidial states of Guignardia are in the genus Phyllosticta. In accordance to nomenclatural decisions of IBC Melbourne 2011, this paper validates species that were in Guignardia but are now accepted in Phyllosticta. The conclusions are arrived based on molecular analyses and morphological examination of holotypes of those species previously described in the genus Guignardia. Thirty-four species of Phyllosticta, viz. P. ampelicida (Engelm.) Aa, P. aristolochiicola R.G. Shivas, Y.P. Tan & Grice, P. bifrenariae O.L. Pereira, Glienke & Crous, P. braziliniae O.L.

Wong & Crous, P. citriasiana Wulandari, Gruyter & Crous, P. citribraziliensis C. Glienke & Crous, P. citricarpa (McAlpine) Aa, P. citrichinaensis X.H. Wang, K.D. Hyde & H.Y. Li, P. clematidis (Hsieh, Chen & Sivan.) Wulandari, comb. nov., P. cruenta (Fr.) J. Kickx f., P. cussoniae Cejp, P. ericarum Crous, P. garciniae (Hino & Katumoto) Motohashi, Tak. Kobay. & Yas. Ono., P. gaultheriae Aa, P. hostae Y.Y. Su & L. Cai, P. hubeiensis K. Zhang, Y.Y. Su & L. Cai, P. hymenocallidicola Crous, Summerell & Romberg, P. hypoglossi (Mont.) Allesch., Rabenh., P. ilicis-aquifolii Y.Y. Su & L. Cai, P. korthalsellae A. Sultan, P.R. Johnst, D.C. Park & A.W. Robertson, P. maculata Wong & Crous, P. morindae (Petr. & Syd.) Aa, P. musarum (Cooke) Aa, P. muscadinii (Luttr.) Wulandari, comb. nov., P. owaniana G. Winter, P. partenocissi K. Zhang, N. Zhang & L. Cai, P. philoprina (Berk. & M.A. Curtis) Aa, P. schimae Y.Y. Su & L. Cai, P. spinarum (Died.) Nag Raj & M. Morelet, P. styracicola Zhang, Y.Y. Su & L. Cai, and P. vaccinii Earle are accepted in this study based on examination of type material of “Guignardia” species, including three new combinations. It is anticipated that other species of Phyllosticta will be accepted, following future molecular studies.

Lemon grass, thyme and rose essential oils have been found to have inhibitory effects against the mycelial growth of Aspergillus niger under in vitro conditions. Results indicated that all essential oils treatments significantly reduced the linear growth of A. niger. Complete reduction was obtained with thyme and lemongrass at concentration of 0.5%.Moreover, essential oils used to coat seeds and sown in soil drenched with B. subtilis resulted in a significant reduction of crown rot incidence of peanut, at both pre- and post-emergence stages under field conditions. Rose, thyme and lemongrass in descending order could reduce the incidence of crown rot at both pre-and post-emergence stages at the two successive growing seasons 2011 and 2012. Higher protective effect against crown rot incidence at both pre- and post-emergence growth stages was observed when essential oils integrated with B. subtilis as an applied soil treatment than that of individual applied treatment. Also Rhizolex-T as seed treatment could significantly reduce disease incidence over the control treatment. As for the harvested yield, all treatments were significantly higher than that in the control treatment. The treatments of essential oils as seed dressing plus the bio-agent B. subtilis showed higher yield production than those treatments using an essential oil or B. subtilis alone. The present results show that application of essential oils in integration with the bio-agent B. subtilis may be considered as an applicable, safe and cost-effective method for controlling such soil-borne diseases.
