In fact, antagonistic organisms usually do not act suddenly and drastically on their prey or target organism because they need some time to develop an

Friedemann Buddensiek,Christof Rapp are many examples in the litterature illustrating the potential of these organisms as biocontrol agents under controlled or laboratory-scale environments. However, isolates effective under controlled conditions did not always work in the field. The ability of potential antagonists to survive, grow

This is especially true with soilborne pathogens which are deeply embedded in the soil and are strongly affected by antagonists. An alternative means of control would be to use sublethal dosages which weaken the pathogen and enab

There is still much that is not known about TAD, so the extent to which current BCAs simulate the mechanisms of TAD is debatable; but if they do, the findings reported here have implications for a) interpretation of work based on seedling-

This hypothesis was proposed as the result of studies of suppressive soils. In order to explain the suppressiveness of the soil from Chateaurenard, Rouxel et al. (1979) first suggested the existan

Christoph Ferber,Annegret Middekease relies on the integration of different control measures such as soil disinfestation, use of partially resistant cultivars, raised bench cultivation, and fungicide application. A new, innovative control measure, widely investigated over the past 10 years, is represented by the use of antagonistic
