From the President I’m very pleased to announce that we have forged a new collaboration with market leading magazine Mushroom Business, the latest copy of which you are now holding in your hands. As you know, the ISMS informed its members in the past through our Mushrooms International Newsletter in print, and from 2006 – 2008 as an e-newsletter. For several reasons, this publication has been discontinued. In recent years, ISMS has worked with the publisher of Mushroom Business (Global Roel Media) to our mutual benefit. This is not surprising, as both parties further the growth of the international mushroom industry through independent dissemination of information on a global scale. Through its vast readership base and firm network within the worldwide industry, we believe that Mushroom Business constitutes a stable, readable and informing plat- form for the ISMS messages and news, besides or other publications in print and online. So from now on, you will find ISMS contributions on this page, informing you on everything we are up to. If you have any news you want to share, please mail to the editor:
roel@mushroombusiness.com
Cheers, Greg Seymour, ISMS President.

CULTIVATION TIP ADVISIE
AA fast, accurate, and inexpensive mushroom disease diagnostic sys- tem that facilitates routine disease surveillance on farm has been the Holy Grail for scientists and industry over the past decade. Lots of indi- vidual scientists from all over the world have been making contributi- ons to the knowledge bank but an integrated system that supported a “commercial service” to mushroom growers has eluded the industry. But that may be all about to change. In the mid 2000s, ISMS facilitated a global collaborative project between scientists in South Africa, New Zealand, The Netherlands, Ireland, USA and Australia to develop a disease surveillance capability for growers around the world. Results were encouraging, but funding ran out before all the objectives could be achieved. Since then, scientists in several countries have continued building on the ISMS project. Just last week I heard an exciting story about some further develop- ments in SA. A grower was singing the praises of a disease monitoring service that he had recently used on his farm to tackle a persistent disease problem. A technician from the University of Pretoria (one of the collaborators in the ISMS project) had “swabbed” his farm and subsequently tested for a range of typical mushroom pathogens using molecular biology techniques back in the laboratory. The results identified which diseases were present, where the infection source(s) were, and what management procedures needed to be implemented to bring the diseases under control. The grower followed the recom- mendations and noticed a significant decrease in disease symptoms. But that’s not where the story ends. Disease had been a constant companion on the farm over an extended period, so even though the disease symptoms seemed to be under control, the grower arranged for the farm to be re-swabbed. He wanted greater confidence that his disease management had been effective in minimizing the risk of the disease(s) returning. The results were encou- raging. Good disease control had been achieved in the locations where pathogen loads had been identified in the initial testing. The results

Mushroom Disease Surveillance Capability – the Holy Grail
reassured the grower that his control strategy was appropriate and his staff where implementing it effectively. However, there were a few surprises that highlighted the benefit of routine testing. The re-swabbing identified some new disease hot spots not previously known. If these had not been picked up in the second survey and treated promptly, they would have become a future source of reinfection. Action was taken immediately and the persistent disease remains under control. Theory and practice converged and routine surveillance is now part of the farm’s disease management program. The search for the Holy Grail has also re-emerged in Australia. Work has restarted at the Marsh Lawson Mushroom Research Institute and Sydney University. The project is also building on the outputs from the ISMS pro- ject including the use of material from the ISMS International Mushroom Pathogen Collection located in Pretoria and Wageningen. The aim of the initiative is to have a pilot service operating in the industry before the end of the decade. I’m hearing other bits and pieces from other research projects around the world too. With a bit of luck, hard work, financial support, and continuing scientific collaboration, the world may yet see a commercial mushroom disease surveillance service available to growers sooner than predicted when the ISMS project stalled.
developments and the science of mushrooms and to stimulate exchange of new ideas between growers and scientists around the world. ISMS sponsors a major international congress on mushrooms, which is held every 3-5 years. Other events are endorsed and supported by ISMS working with national committees. The Society is governed by a council which includes a member appointed by each Corporate Member and six members elected by ballot of the individual members. The Council elects the President, Vice-President, Secretary, Treasurer, as well as the past president to be the Executive Com- mittee.
ISMS Congress 2012 Things are coming together nicely for the 18th ISMSC in fascinating Beijing, China on August 26-30, 2012. This event will be the highlight for the mushroom indus- try internationally next year. The main purpose of this Congress is to promote the development of mushroom industry as well as to present the latest developments. In addition to the scientific communication, new varieties, new products, new technolo- gies and latest publications will be showcased. The theme of the Congress is Mushroom and Health, which will focus on (I) The development and prospect of industrial situation; (II) Production and technology; (III) Nutrition and health. The Congress will consist of keynote lectures, plenary sessions, oral and poster presentations. Key note speakers will include Dr. Anton Sonnenberg (Breeding for the Future), Dr. Shiuan Chen (Protective effects of Agaricus bisporus), Prof. Yu Li (Chinese mushroom industry) and Dr. Ian R. Hall (Mycorrhizal mushrooms). Farm visits are planned to the Tongzhou District on August 29. The 18th Congress will be held at Beijing International Convention Center (BICC), which is located close to the main venue of the 2008 Olympic Games and touristic highlights. This is an event not to be missed, so get it in your diary and make sure you’ll be part of it!

Most varieties of brown mushrooms have a greater tendency to form clusters than white strains. You often see more clustering with pre-pinners and when pinheads tend to ap- pear between lumps of casing soil rather than on top. A few clusters are not a problem, but too many will have a negative effect on the picking performance, and cause the picking costs to rise. As well as differences between varieties, there are also differences in one and the same variety. A certain batch number is sometimes more susceptible than another. Growers can limit the number of clusters. Lay the casing soil slightly more densely, and not too coarse in structure. This will encourage the mycelium to grow better towards the surface of the casing soil. With regard to clusters, beds with a more visibly white appea- rance are preferable to beds with a dark casing soil surface. The mycelium should also be allowed some vegetative growth during recovery and at the start of cool down. On relatively white beds, brown mushrooms normally form enough pinheads that deve- lop well. We recommend reducing the RH considerably five to six days after cool down has started to promote further development of the pinheads. If pinhead development stagnates at this stage, more clusters will be formed.
