This volume includes the contributions from two workshops: the 6th International Workshop on Pome fruit Diseases held in Lindau, Germany, 31 August – 5 September 2002, and the 7th International Workshop on Orchard Diseases, held in Piacenza, Italy, 31 August – 3 September 2005. The Bulletin contains 41 contributions: 16 from the Lindau meeting and 25 from Piacenza. They concern several aspects of the most important fruit crop diseases, including epidemiology, biological and integrated control. Also diseases of increasing importance in Europe, like brown spot and bark canker on pears, were deeply investigated by several contributions of participants and round tables. In aggregate, 78 scientists from 15 countries in Europe, United States and Canada attended the Workshops. The local organization of the Workshops was handled by Peter Triloff and myself in collaboration with competent co-workers, for Lindau and Piacenza, respectively. Both organizers took care of the scientific planning and also handled the organizing details to guarantee successful meetings. In both occasions excursions were planned to visit pear and apple orchards both conventional and organic, showing different cropping methods, pathological problems, and strategies of fungicide applications. The next Workshop of this subgroup will be organized in Denmark in 2008, probably in October, by Arne Stensvand and two colleagues from Denmark. I believe that this Bulletin will be an useful tool for scientists and technicians as an updating of the knowledge about epidemiology and optimal control strategies for both well known and emerging diseases.

  • Extension Plant Pathology Update July 2013
    Extension Plant Pathology Update July 2013 Volume 1, Number 6 Edited by Jean Williams-Woodward Plant Disease Clinic Report for June 2013 By Ansuya Jogi and Jean Williams-Woodward The following tables consist of the commercial and homeowner samples submitted to the UGA plant disease clinics in Athens and Tifton for June 2013 (Table 1) and for one year ago in July 2012 (Table 2). The wet weather has been great for plant growth, as well as plant diseases. Various root rots, leaf spots and rusts have been diagnosed on almost all crops. The incidence of bacterial diseases will increase through July, as will Sclerotium rolfsii and Rhizoctonia diseases. We also continue to confirm Rose Rosette-associated virus on Knock-Out rose samples. Also, Dr. Little has confirmed Cucurbit Yellow Vine Disease on squash, caused by the bacterium, Serratia marcescens. She has a graduate student working on this disease and wants to know if you are seeing it. See page 7 for her summary of cucurbit diseases, including cucurbit yellow vine disease. Looking ahead with the current weather pattern, we expect to see more leaf and root diseases on all crops. This isn’t a surprise. Warm days, cooler nights, high humidity, wet foliage and saturated soils are the recipe for plant disease development. Again, it is an exciting time to be a plant pathologist.

Invasive plants may benefit from reduced pathogen impact when competing with native plants, but suffer if mutualists are unavailable. Root samples of the invasive dune grass Ammophila arenaria and the native dune grass Leymus mollis were collected from a Californian foredune. We utilised the Illumina MiSeq platform to sequence the ITS and LSU gene regions, with the SSU region used to target arbuscular mycorrhizal fungi (AMF). The two plant species largely share a fungal community, which is dominated by widespread generalists.

  • Fungicide Sensitivity of Corynespora Cassiicola and Assessment Of
    FUNGICIDE SENSITIVITY OF CORYNESPORA CASSIICOLA AND ASSESSMENT OF MANAGEMENT OF TARGET SPOT OF COTTON IN GEORGIA by: MA. KATRINA SHIELA E. LAUREL (Under the Direction of Robert C. Kemerait, Jr.) ABSTRACT Target spot, caused by Corynespora cassiicola, is a serious foliar disease of cotton in the southeastern United States. Baseline (current) isolates of C. cassiicola were tested for sensitivity to metconazole (DMI), fluxapyroxad (SDHI) and pyraclostrobin (QoI). Further work compared fungicide sensitivity of C. cassiicola isolates from cotton to isolates from other hosts. Field experiments were conducted to establish a relationship between fungicide sensitivity in laboratory experiments and fungicide efficacy in managing target spot on cotton. Based on the sensitivity distribution, all isolates tested were considered sensitive to fungicides. However, these sensitivities varied among isolates offering an early indication that resistance can happen in the future. Additionally, all fungicides reduced disease severity and premature defoliation; however, Priaxor (pyraclostrobin + fluxapyroxad [QoI + SDHI]) proved to be most effective. Results from this study can help optimize fungicide sensitivity monitoring practices in an effort to improve fungicide use patterns for optimum disease management.

Crous, [email protected] Abstract: In 2007 a new Stemphylium leaf spot disease of Beta vulgaris (sugar beet) spread through the Netherlands. Attempts to identify this destructive Stemphylium sp. in sugar beet led to a phylogenetic revision of the genus. The name Stemphylium has been recommended for use over that of its sexual morph, Pleospora, which is polyphyletic. Stemphylium forms a well-defined monophyletic genus in the Pleosporaceae, Pleosporales (Dothideomycetes), but lacks an up-to-date phylogeny. To address this issue, the internal transcribed spacer 1 and 2 and intervening 5.8S nr DNA (ITS) of all available Stemphylium and Pleospora isolates from the CBS culture collection of the Westerdijk Institute (N = 418), and from 23 freshly collected isolates obtained from sugar beet and related hosts, were sequenced to construct an overview phylogeny (N = 350). Based on their phylogenetic informativeness, parts of the protein-coding genes calmodulin and glyceraldehyde-3-phosphate dehydro- genase were also sequenced for a subset of isolates (N = 149).
