The use of composted woodchip as a substrate for growing varieties of edible mushrooms Organic Eprints
Frost, D; Clarke, A.
The world market for edible mycorrhizal mushrooms has experienced considerable growth over the past two decades with annual production estimated to exceed 14 billion USD. The market continues to grow due to interest in the nutritional and health benefits of edible mushrooms. The size of the market for speciality mushrooms has also increased and the overall market trend has been towards fresh rather than canned product. There are a number of different cultural methods in commercial use, with a wide variety of species produced on different substrates. The aim of this project was to evaluate woodchip compost as a substrate to produce edible mushrooms. Woodchip compost appears to have potential as a growing medium but more development is necessary to make this...

Wireworm Control using Fodder Rape and Mustard – evaluating the use of brassica green manures for the control of wireworm (Agriotes spp.) in organic crops Organic Eprints
Frost, D; Clarke, A; McLean, B M L.
In a field experiment at ADAS Pwllpeiran in 2001, brassica green manures were grown for 6 weeks and dug in before planting King Edward potatoes, to see if they suppressed wireworm in the crop. There was a trend for potatoes grown after mustard to suffer less damage from both wireworms and slugs than potatoes grown after fodder rape or no green manure, but the differences were not significant. Further trials, with longer green manuring periods, are needed to establish if there is a benefit, and whether the breakdown products of brassica green manures are toxic to wireworms.
