ISMSNEWS Mushroom Week update T


he biggest week on the 2016 mushroom industry calendar will be Mushroom Week in Holland. The 19th ISMS Congress will combine with the 34th Mushroom Days from 29 May to 3 June. The Organizing Committee is well advanced in its planning to provide everyone in the industry with a smorgasbord of oppor- tunities for the mushroom experience of a lifetime. Check out what’s in store on both websites: www.isms2016.com and www.champignondagen.nl/en. From the scientific and marketing programs at the Congress to the technical and commer- cial innovation at the Mushroom Days, from the excitement and beauty of Amsterdam to the history and hospitality of Den Bosch,


Mushroom Week brings it all together into one global networking event that no one in the mushroom industry should miss! With only 7 months to go, everyone should start registering for the Congress, making accommodation arrangements, and plan- ning their travel. The closing date for abstracts for the 19th ISMS Congress is 1 December 2015. That’s not very far away. Everyone planning to present a paper or poster are urged to submit their abstract as soon as possible and certainly before the closing date. Following the success and popularity of pilot marketing sessions at earlier ISMS Congresses, organisers of the 2016 Congress are currently developing an expanded marketing program (global


marketing efforts, success stories, consumer research) that will run concurrently with the scientific sessions.


Other events


The ISMS International Flammulina velutipes (Enoki) Working Group is holding its first symposium on 12 and 13 November 2015 in Fuzhou, China. Dr Arend van Peer is the working group convener and organizer of the symposium. The Working Group, only recently established, has allready 30 researchers from 10 different countries as active members. Interested in joining? Con- tact Arend by email: 2756095644@qq.com, and stay tuned for the announcement of further working groups in 2016.


Wanda Realm Hotel, Zhangzhou, China is once again the venue for Chinese Mushroom Days (15-17 November), the last big event on the 2015 global mushroom calendar. This world-class event provides international and local delegates with a platform for technical information, commercial opportunities, and a wonderful environment for networking. It has become the must-go meeting place of the mushroom industry in Asia and an experience you should not miss.

CULTIVATIONTIPS ADVISIE Preventing blotches

Mushrooms presenting yellow/brown patches are often seen on the beds. The fi rst blotches are usually seen where the mushrooms touch. Bacterial infection and the resulting discolouration degrade the mushrooms from quality I to quality III or even make them unsalable. After having noticed the fi rst blotches, growers often increase evaporation at the start of the fi rst fl ush to prevent the problem spreading. This is generally not a bad idea, but it does not solve the problem. The true culprit behind these blotches is too much condensation on the casing soil during pinheading/pin development. Very wet casing soil combined with pins forming deep in the casing also leads to problems. Most condensation is formed when moisture in the air falls onto the cold casing soil. Condensation occurs if the casing soil temperature falls below the dew point of the room air (wet bulb temperature). If condensation accumulates for too long in places where pinhead are formed (see lower half of photo collage), problems with yellow/brown blotches will occur in the fi rst fl ush. It is important to prevent conden- sation or ensure that any condensation formed is evaporated by lowering the RH and possibly increasing the circulation.
