The effect of fungicides on the mycoflora of leaves of Triticum aestivum L.

Janusz Błaszkowski

Abstract


The effect of three foliar fungicides on ihe mycoflora associated with leaves of Triticum aestivum cv. Kolibri cultivated in ihe field was investigated. The total number of fungi associated with leaves increased as the season progressed. The fungicide which reduced consideraMy the number of both fungal colonies and species was Funaben K. The decline in the total number of fungi species of T. aestivum leaves was largely due to the reduction in the number of Altenaria alternata species and non-sporulating fungi. None of the fungicides reduced the proportion of leaves with Cladosporium spp. At some stages, the increase in the occurrence of some fungi species was accompanied by a decrease in the number of other fungi.
