Aerobiology of “closed” agricultural systems

In many, mostly temperate regions of the world, crops are cultivated in completely or partly closed environments. Problems concerning the dissemination of fungal spores or bacterial cells in these systems are comparable to those in open systems, but there are many supplementary problems, which have hardly been investigated up to now.Now the application of chemicals in agriculture is strongly discussed worldwide, it will be of the utmost importance to know more about the aerobiological principles of spore dissemination in closed, more or less conditioned environments, to be able to create better disease management programs for plant diseases on crops cultivated in those conditioned environments.In this paper problems concerning the dissemination phase of the fungal infection cycle developing in “closed” spaces will be discussed.
