Botrytis cinerea spore balance of a greenhouse rose crop Inra
Boulard, T.; Chave, M.; Fatnassi, H.; Poncet, C.; Roy, J.C..
Fungal pathogens are among the most virulent bioagressors of protected crops. For sustainable plant production and to protect the crop against these airborne organisms one must determine their origin, i.e. whether they come from outside the greenhouse or are produced inside it.We considered Botrytis cinerea spore concentration as a particular physical species which is transported by air in the same way as heat, CO2, water vapour or any tracer gas. We constructed a mass balance of the viable Botrytis spores on the whole-greenhouse volume to assess the inside production of spores and their exchanges.The different elements in the spore balance are considered and are determined experimentally:• spore transfer into or out of the greenhouse is deduced from the...
