MODELLING BOTRYTIS CINEREA SPORE EXCHANGES AND PRODUCTION IN UNHEATED GREENHOUSES

摘要: SUMMARY In order to devise optimal and sustainable strategies protect greenhouse grown crops against Botrytis cinerea, production of spores inside the greenhouses exchanges with outside need be monitored. Such knowledge could used for adequate timing measures aimed at limiting entry exogenous inoculum others multiplication endogenous inoculum. an earlier study, a model based on spore mass balance was developed estimate B. cinerea number entering leaving greenhouse. This successfully in heated glasshouse. As much tomato also occurs more open less controlled conditions, present study testing non plastic (tunnels) where environmental parameters known influence differ from glasshouse setting. When diseased plants were tunnel, over 24 h estimated by equivalent 5 10% maximum potential amount plants, which coherent likely released action wind sporulating lesions. Exchange toward outside. tunnel empty or contained disease-free fewer exchanged movement globally tunnel.
