Cultivation of edible mushrooms Agaricus Bisporus in Europe is an economically valuable Industry that employs 50,000 employees with a production 965,000 tonnes and 1,300M Euros sales. Pests and diseases in this industry causes loses of 60M Euros related to Pest control. The main pest insects causing crop losses in Europe are Sciarid flies, whereas the main diseases are the fungus Verticillium, Mycogone, Dactilium and Tricoderma. Many chemicals are no longer approved for use, and with an increased demand for reduced pesticide use. Mushroom growers have an increased pressure to implement these alternatives on the basis of Regulation (EC) No 1107/2009 and Directive 2009/128/EC. Quick actions and IPM solutions are therefore urgently needed for mushroom growers as reported by their national associations in order to adapt to a stringent legislation to reduce pesticide use.The main aim of BIOMUSH project is to help European mushroom growers to implement IPM as part of their growing activities both to comply with the upcoming legislation and to reduce crop losses and production costs by efficiently manage pests and diseases. The main objectives: -Develop a tool for early detection of mushroom fungal diseases in situ to facilitate the control of competitor fungi and fungal diseases increasing productivity by 4%; -Provide novel biopesticides for the treatment of pests and diseases in mushroom; -Develop crop specific guidelines for Integrated Pest Management in mushroom crops in Europe; -Training to professional users and distributors.By facilitating the implementation of IPM techniques in mushroom, growers will be able to comply with the upcoming regulation which encourages natural pest control mechanisms reducing pesticides use per farm by at least 70% (3,472 Tons in Europe after 5 years). The combined approach of early detection of fungal diseases and use of biopestices will provide a tool that will reduce yield losses caused by pests and diseases by around 48%.
