The Almond Board of Australia are pleased to present the presentations given to attendees of the workshops held in Virgina and Loxton in November of 2017. To view the information presented select the images below.
On the 1st and 2nd of November Florent Trouillias and Themis Michailides provided an overview of Canker Diseases and research that has been conducted by their team at UC Davis. The workshops were well attended with some good discussion and tips provided to minimise risks of infecting trees with canker diseases. An announcement made at the workshops was that Florent and Themis will both be working closely with Mark Snosnowski in his disease management project to help identify trunk diseases observed throughout the Australian Almond industry. Below is a biography of both of the presenters as well as a links to their presentations.
Florent Trouillas is an assistant specialist in Cooperative Extension at the Kearney Agricultural Research and Extension Center (UC’s largest off-campus agricultural research facility, located in Parlier, California). He is part of the UC Davis Department of Plant Pathology, and specializes in fruit and nut crop pathology. His current projects include:
- Investigating and diagnosing new and emerging diseases of pistachio, assessing the status of California pistachio tree health
- Investigating the etiology of limb dieback and trunk and scaffold canker diseases of almond, improving diagnosis and management strategies
- Etiology and management of sweet cherry canker diseases, investigating fungi associated with canker diseases in sweet cherry and chemical control methods against Calosphaeria canker, Eutypa dieback, and Leucostoma (Cytospora) canker
- Management of Phytophthora root and crown rot of almond, evaluating the effectiveness of several new fungicides against Phytophthora species
- Pistachio bushy top syndrome, influences of colonization and infection by Rhodococcus fascians on flowering and fruit set on Pistacia vera
Themis Michailides received his first M.S. degree in agriculture development and irrigation from the Agricultural University in Athens, Greece and he has M.S. and Ph.D. degrees in plant pathology from the University of California (UC), Davis. Themis was a post-doctoral research associate, first at Oregon State University at Hood River, and later at UC Davis. He served on the faculty in the Department of Plant Pathology, UC Berkeley, and was promoted to associate plant pathologist in 1992. He is currently a plant pathologist at the Kearney Research and Extension Center with research responsibilities in fruit and nut crop diseases.
His research work focuses on:
- Managing Alternaria late blight disease of pistachio by cultural and chemical control approaches
- The biology of Botryosphaeria dothidea which causes panicle and shoot blight of pistachio, band canker of almond, and a severe shoot blight in walnut
- The phylogenetic studies of Botryosphaeria spp. attacking nut crops as well as in using molecular and conventional techniques to detect and predict these diseases
- The detection of pathogens, such as Monilinia fructicola (stone fruit), Botrytis cinerea (grapes, kiwifruit, pome and stone fruit, figs, and pomegranates), Alternaria alternata and other Alternaria spp. (pistachio), B. dothidea and Fusicoccum sp. (pistachio, almond, walnut, and other tree hosts), Aspergillus niger and A. flavus (pistachio, figs, grapes, and raisins)
- The study of the survival of Monilinia fructicola, the pathogen causing brown rot, prediction of the disease risk, and management of the disease by cultural and biological methods
- The study and understanding of the life cycle and infection of nut crops and figs by the aflatoxigenic fungi Aspergillus flavus and/or A. parasiticus
