Abstract
A Petri plate test is described which can be used to screen for pathogenicity of fungi from diseased seedlings, plant roots, seeds or soil. Seedlings grown axenically on water agar are inoculated with test fungi and infection observed directly. The test method is also valuable for fungal identification because it often promotes formation of fruiting structures which are not normally produced on conventional media. Sealed plates can be used for long-term storage of fungal cultures.
